The flaw detector is characterized by the fact that it includes an elastic cuff, the specified control sensors are installed on the periphery of the cuff adjacent to the inner surface of the pipeline. The main disadvantage of such a flaw detector is that the passage of pipeline sections with significant geometry defects in its cross section is accompanied by the removal of sensors from the undeformed portion of the pipeline near the geometry defect, as well as the collapse of the cuffs with sensors. When monitoring a pipeline consisting of pipes with significantly different pipe wall thicknesses, for example, in the presence of previously repaired sections of the pipeline, in areas with increased wall thickness, and also if there is an extraneous fixed object on the inner surface of the pipeline, the passage of the sensor carrier may be accompanied by a collapse of the cuff with loss of orientation of part of the sensors.

The flaw detector is characterized in that the runners are pivotally connected to the flaw detector body and pressed against the inner surface of the pipeline c. using elastic supports (elastic or metal) mounted on the flaw detector body, which allows the runners to bend around minor geometry defects in the pipeline section (dents), underlay rings and similar inhomogeneities.

The specified limitation in use arises due to the limited extraction of the runners in the direction of the pipeline axis, due to the construction of the mount runners. In addition, the fastening of the runners takes place (the length of the fastening along the axis of the pipeline is greater than the length of the runner with control sensors along the axis of the pipeline) in conditions of limited space for the placement of control sensors and their fastening inside the pipeline. Therefore . . if it is necessary to overlap the scanning zone on the surface of the pipeline wall with several sensors in order to obtain a high linear resolution in measurements, it becomes necessary to fasten several belts of runners on the flaw detector body, the length of each of which significantly exceeds the length of the sensors and runners along the pipeline axis, and the total length of belts in this case, it develops depending on the number of skid belts used (sensor holders), which It increases the flaw detector's cross-country ability at bends and increases the length of the flaw detector when placing snake belts on different sections of the flaw detector, which complicates the possibility of its storage in the launch tube of in-tube shells.

The prototype for all variants of the claimed group of utility models is an in-line flaw detector (RF patent RU2133032 dated 10.07.99, IPC G01 N27 / 83 (Engineering Center VNIIST-SEARCH CJSC); and GB2097537 dated 03.11.82, IPC G01 N27 / 83 (British Gas Corporation)), which is passed inside the pipeline under examination, comprising a housing, control sensors installed on the housing that are sensitive to at least one parameter that reflects the state of the pipeline wall, as well as measuring instruments and processing of measurement data, with sensors installed around the perimeter of the wok y axis of symmetry flaw in h W v runners made able to abut an inner surface of the pipeline, each skid is mounted at least one sensor. The flaw detector is characterized by the fact that on its body there are many runners around the perimeter around the axis of symmetry of the flaw detector, each of which is fixed to the flaw detector body using an elastic link (lever) that can slide along the inner surface of the pipeline. The design of the flaw detector provides the flaw detector through the cross section of the pipeline with minor geometry defects (dents, underlay rings and similar inhomogeneities). The main disadvantage of such a flaw detector is that, in order for 4.J to have a flaw detector of this design with high passability (the ability to pass through significant narrowing in the cross section), the lever must have a considerable length. At the same time, to maintain the relative orientation between the levers for uniform coverage of the perimeter control sensors in the pipeline section, the stiffness of the levers should be significant. However, a significant stiffness of the levers during the passage of the obstacle detector in the form of underlay rings, gate valve elements and similar obstacles leads to shock loads on skids with control sensors and. damage to runners and / or control sensors or to loss of orientation of control sensors. The claimed group of utility models solves the problem of increasing the efficiency of monitoring the walls of the pipeline when examining pipelines with long narrowings, variable diameter and other significant defects in the geometry of the profile of the pipeline. W / v ,, The main technical result (common for all variants of the group) obtained as a result of implementing any of the variants of the utility model group described below is a decrease in the relative amount of data by which defects cannot be identified due to unacceptable changes in the orientation and indentation of the control sensors from the inner surface of the pipeline or damage to the control sensors. The mechanism for achieving the indicated technical result consists in the fact that the mounting of control sensors on the flaw detector body, the location and mounting of the means of influencing the pipe wall according to the options allows us to separate the task of enveloping minor geometric defects in the pipe cross section while maintaining the sensitivity of the control sensors to pipe wall defects and the significant envelope problem defects in the pipeline section (dents) due to the removal of control sensors from the pipeline wall in the presence of significant defects, while maintaining the compactness of the placement of the arrays of sensors, which allows you to keep the control sensors and their mount in good condition and continue to carry out measurements with high resolution after passing through the flaw section of a narrowing or obstacle.

The indicated preferred embodiment enhances the main technical result: the indicated sensor mounting design avoids the removal of sensors from the inner surface of the pipeline due to the rebound of the sensor holders from the washers welded to the inner surface of the pipeline and similar geometry defects in the cavity of the pipeline and preserves the orientation of the sensors relative to the axis of the pipeline (within the bend of the sensor holders) when passing sections of the pipeline with geometry defects in its section, ecause the presence of polymer units based on an inner surface of a pipeline, leads to the pressing force of the polymeric element to the pipe wall, at 3-7 times the allowable pressing force sensor itself (sensor holder) to the wall of the pipeline. Moreover, erasing the material of polymer elements does not damage the sensors themselves. An additional technical result obtained as a result of the implementation of the invention is that the fastening of the sensor holders of the claimed design allows compact placement of the sensors and

, h the distance between the attachment point of the elastic link on the flaw detector body and the surface of the cylinder into which the flaw detector fits; the runner includes one or more plates, elastically mounted on the bracket so that the plates are able to adhere to the inner surface of the pipeline when the flaw detector is moving inside the latter, while part of the surface of the plate forms a contact pad with the inner surface of the pipeline, on the portion of the plate forming the specified contact pad , from the side opposite the indicated contact pad, these sensors are fixed, while on each plate several of these sensors are installed, holding spruce sensor also comprises a resilient metal or polymeric backup, which abuts the side of symmetry axis flaw sensors and provides an elastic biasing effect in the direction of the axis of symmetry flaw; the skids are mounted on the flaw detector housing in the form of at least two pairs of belts around the symmetry axis of the flaw detector at a predetermined distance along the symmetry axis of the flaw detector between the belts in each pair, which is no more than 0.2 distances along the symmetry axis of the flaw detector between adjacent pairs of belts and not more than 0.5 diameter of the cylinder into which the flaw detector fits; each holder is fastened with a rigid element with at least one holder from the adjacent snake belt; while the runners in a pair of belts are set alternating in a checkerboard pattern; the distance between the centers of the sensors in each run along the perimeter in a section perpendicular to the axis of symmetry of the flaw detector is not more than 9 mm; the belt installed around the symmetry axis of the flaw detector of snakes forms sectors of several snakes, alternating with sectors formed by .73 / ЗЗ with Р

In addition, the mounting of sensor skids in the flaw detector of the claimed design takes up an insignificant space (the mounting length along the axis of the pipeline is much less than the length of the skid with control sensors along the pipeline axis) in conditions of limited space for placing the control sensors and their mounting inside the pipeline, and mounting several sensor holder belts for overlapping the scanning zone on the surface of the pipeline wall with several control sensors with Strongly obtaining high linear

resolution in measurements leads to an insignificant total length of the belts.

The claimed flaw detector is a device for non-destructive testing of materials and products (scanning materials and products and processing measurement data, subsequent identification of data) to detect defects in the structure of the material, determine the geometry of the products (geometric parameters of the products: pipe profile, wall thickness and others), including including defining product geometry defects. Sensors that are sensitive to diagnostic parameters that reflect the state of the wall of the pipeline (control sensors) are sensors for non-destructive monitoring of the state of the wall of the pipeline: ultrasonic, magnetic, electromagnetic, magneto-optical, optical, electromagnetoacoustic, profile sensors of the cross section of the pipeline and other control sensors that are sensitive to any parameter reflecting the state of the pipeline.

When solving the problem of ultrasonic thickness gauging, ultrasonic sensors are used, ultrasonic pulses are emitted perpendicular to the inner surface of the pipeline. After emitting ultrasonic pulses, the ultrasonic sensors switch to receive reflected pulses and receive pulses reflected from the inner wall, pulses reflected from the outer wall of the pipe, or pulses reflected from the wall defect area, measure the time that elapses from the moment of receiving the pulse reflected from the inner surface of the pipeline cavity, until the moment of receiving a pulse reflected from the outer surface of the pipeline wall, which characterizes the thickness of the pipeline wall, while on the wall

pipe, which is measured using ultrasonic sensors, is a parameter that reflects the state of the pipe wall.

In order to detect cracks in the pipeline wall by ultrasonic methods, ultrasonic pulses are emitted at an angle near IT - IQ to the normal to the inner surface of the pipeline. These pulses are partially reflected from the inner surface of the pipeline wall, from the outer surface of the pipeline wall, or from a crack-like defect. Partially ultrasonic pulses pass through the boundaries of the media or are reflected, weakening the useful reflected pulse. After the emission of ultrasonic pulses, the ultrasonic sensors switch to the reception mode of the reflected pulses and receive pulses reflected from the crack-like defect.

The obtained data on the time intervals corresponding to the travel time of the ultrasonic pulses and the pulse amplitudes are converted and recorded in a data storage device. In this case, the value of the number of pulses reflected from crack-like defects is a parameter reflecting the state of the pipeline. Another parameter reflecting the state of the pipeline is the amplitude of the pulse reflected from the crack-like defect and characterizing the depth of the defect in the pipe wall.

When magnetic control of the pipeline wall is used, magnetic sensors (magnetic leakage sensors) are magnetized, a certain region of the pipeline wall is magnetized (to a saturation state), and magnetic field components are measured using magnetic field sensors near the magnetized region of the pipeline wall. The measurement of the magnetic field is carried out by periodically referring to the magnetic field sensors (by interrogating the sensors). The presence of cracks or defects associated with the loss of metal (corrosion, scoring) leads to a change in the magnitude and nature of the distribution of magnetic induction.

Moreover, the measured magnitude of the leakage of magnetic flux is a parameter that reflects the state of the pipeline.

Similarly, in-pipe inspection is carried out by periodically starting and / or interrogating sensors of a different type (magneto-optical, optical, electromagnetic-acoustic, sensors of the cross-sectional profile of the pipeline).

Figure 1 shows an in-line flaw detector for in-line inspection of pipelines with a nominal diameter of 56 (1400 mm). The flaw detector housing includes a sealed enclosure in which the measuring instruments and processing of measurement data are installed: electronic modules for

performing measurements, processing and storing measurement data on data storage devices based on the on-board computer, as well as sensors of external pressure and temperature of the pumping medium, a flaw detector angle sensor around its own axis, and a battery.

An array of sensors installed in the holders of sensors encircling the flaw detector is installed on the flaw detector housing, some of which are shown at positions 15-26 in FIG. Sensor holders are installed around the perimeter around the axis of symmetry of the flaw detector. Two flanges of wheels 13, 14 and elastic polymer cuffs 11, 12 are also installed on the flaw detector housing, which ensure centering of the projectile in the pipeline and its progress in the pipeline with the flow of the transported medium. The flaw detector also has a meter for the distance traveled inside the pipeline. The distance meter and sensors are connected to the indicated electronic modules installed in a sealed enclosure. The sensors are installed in the form of three pairs of rows around the axis of symmetry of the flaw detector of figure 1. The sensor holders from the first row are shown at positions 15, 16, 17, 18 in FIG. 1, the second row at 19, FIG. 1, the third row at positions 20, 21 of FIG. 1, the fourth row at 22, 23, 24 of FIG. 1, fifth row position 25 of figure 1, the sixth row, position 26 of figure 1. In this case, the first and second rows (15, 16, 17, 18, 19 of FIG. 1) form the first pair of rows; the third and fourth rows (20,21,22,23,24 figure 1) - the second pair of rows, the fifth and sixth rows (25, 26 of figure 1) - the third pair of rows of sensor holders. In each pair of rows, the sensor holders are staggered. The distance along the axis of symmetry of the flaw detector between the rows in each pair of rows is about 0.3 of the length of each lever on which the sensor holder is mounted.

Each sensor holder is mounted on the flaw detector housing using a pair of levers 41, 42 of FIG. 2, capable of turning in a plane.

passing through the axis of symmetry of the defectoscope, each of these levers has one axis of rotation in the flaw detector housing and one axis of rotation in the sensor holder. In each pair of levers of figure 2 there is a lever 41, a lever 42, while the lever 41 has an axis of rotation 43 on the detector body and an axis of rotation 44 in the sensor holder, lever 42 has an axis of rotation 45 in the detector housing and axis of rotation 46 in the sensor holder. The sensors 47 of FIG. 2 are installed in the sensor holders, with several sensors installed in each sensor holder. However, in the implementation of a flaw detector for inspection of pipelines of small diameter (less than 10), one sensor that is sensitive to the diagnostic parameters of the pipeline can be installed in each sensor holder. The levers are made capable of elastically wringing out the indicated holders with the sensors installed in them in the direction from the symmetry axis of the flaw detector and pressing them against the inner surface of the pipeline using a spring 54 resting on one side of the bracket 56, and on the other hand, in a stop 55 on the rod 53, pivotally connected to one of the lever 41.

In each specified sensor holder, all sensors 47 installed in the sensor holder are located on the rear of the flaw detector (on the right in FIG. 2, at the top in FIG. 1) with respect to both axes of rotation of a pair of levers in this sensor holder (44 and 46). The levers of each pair of levers of the flaw detector are installed parallel to each other (between lines passing through the axis of rotation of each of the levers) and are made capable of maintaining parallelism with each other when they are rotated. The angle of position 48 of FIG. 2 is about 30 fades and shows the position of the pair of levers when the flaw detector is in the pipe of nominal diameter. The sensor holders are made capable of bending in a plane passing through the axis of symmetry of the flaw detector, on levers 41, 42 and on the bracket 49, which is an element of the sensor holder, an arched polymer element 58 made of polyurethane, oriented (facing) with its convex side, is installed on the nose of the flaw detector (broken surface) to the nose of the flaw detector (left in FIG. 2, bottom in FIG. 1), these polyurethane elements rest on the inner surface of the cylinder into which the flaw detector fits, and in full ability to flex in a plane passing through the axis of symmetry flaw in an aft direction flaw. When the flaw detector moves inside the pipeline, polyurethane elements slide along the inner surface of the pipeline. Each of the sensor holders or levers can be equipped with several of these polymer elements. The polymer elements can be mounted directly on the levers (for example, polymer elements 66 and 67 on the levers 61 of figure 4). The sensor holder of figure 2 also contains a bracket 49, pivotally connected to the specified pair of levers, as well as several elastic plates 50, 51, 52, elastically mounted on the bracket 49 so that the plate 51 is able to abut against the inner surface of the pipeline when the flaw detector moves inside the latter, while part of the surface of the plate 51 forms a contact pad with the inner surface of the pipeline, fixed to the portion of the plate 51 forming the specified contact pad, from the side opposite the specified contact pad, sensors 47. The sensor holder may contain several or only one metal or polymer plate instead of three plates 50, 51, 52. Moreover, on each plate 51, several sensors can be installed, as well as one sensor that is sensitive to diagnostic parameters. The sensor holder also contains an elastic metal or polymer support 59, which abuts the sensors 47 from the symmetry axis of the flaw detector and exerts an elastic pressing effect in the direction from the symmetry axis of the flaw detector (in the radial direction), pressing the sensor holder against the inner surface of the pipeline. In the embodiment shown in figure 2, the backup is made of metal. At the end of the lever 41, a rod 53 is pivotally fixed, which focus 55 presses the tension-compression screw spring 54 to the housing element 56 (bracket), the articulated connection of the lever 41 and the rod 53 forms the axis of rotation 57. The spring 54 is in a compressed state, and the sensor holder is pressed in the direction from the axis of symmetry of the flaw detector (upward in figure 2, corresponds to a decrease in angle 48) corresponds to a decrease in the radius of the spring 54. The pairs of levers in each pair of rows are staggered: 31, 34, 32, 35, 33 of FIG. 3, while pairs of levers 31, 32, 33 with sensors tsya to one row, a pair of levers 34, 35 with sensors belong to a different row. The distance between the rows is counted as the distance between the rotation axes of the adjacent levers from each row in the flaw detector housing. 36 in FIG. 3 shows a flaw detector housing element (bracket) on which pairs of levers 31-35 are attached. Each sensor holder can be mounted on the flaw detector housing also with the help of three or more levers. Figure 4 shows another design variant of the sensor holders: a pair of levers 61, 62 are pivotally mounted on an element of the flaw detector housing 60, at the peripheral ends of which a bracket 63 is pivotally mounted, on which 5 sensor holders are installed, belonging to two sensor belts: 64 and 65 .4. The pairs of levers with h sensors mounted around the symmetry axis of the flaw detector form two zones of sensor holders: a belt of sensor holders 64 (a belt of sensors) and a belt of sensor holders 65 (a belt of sensors). A polymer element 66 is mounted on the lever 61 from the front of the flaw detector. A polymer element 67 is also mounted on the bracket 63 from the side of the bow of the defectoscope. These polymer elements allow you to soften the shock in the presence of significant obstacles or distortion of the profile in the section of the examined pipeline. When implementing a flaw detector with magnetic sensors (magnetic flaw detector) in positions 1-7 of figure 1, magnets with ferromagnetic brushes mounted on them should be installed on the flaw detector body, which can contact the inner surface of the steel pipeline. In this case, a closed loop of the magnetic flux is formed: magnets with brushes, a ferromagnetic wall of the pipeline, other magnets with brushes, a ferromagnetic casing of a flaw detector, magnets with brushes. The principle of operation of an in-line flaw detector performed by a magnetic flaw detector is based on the magnetization of the pipeline wall using magnets mounted on the flaw detector body and the measurement of magnetic flux leakage using magnetic field sensors. The magnetic field sensors mounted on the flaw detector body are sensors that are sensitive to diagnostic parameters that reflect the state of the pipeline wall, namely: leakage of magnetic flux in areas of crack-like, corrosion, and mechanical (marks, bumps) defects in the pipeline wall. Rows of pairs of levers with sensor holders: the first, second, third, fourth form sensor sectors alternating with sectors of magnetizing brushes 1-7 of Fig. 1 (which are means of magnetic action on the pipe wall that cause a change in the magnetic field component (diagnostic parameters) measured using the indicated magnetic field sensors, so that the sectors of the magnetic brushes 1,2,3 are installed between the sectors of the magnetic field sensors 15, 16, 17 and 18; the sectors of the magnetic brushes 4, 5, 6, 7 are installed between the sensor sets in a magnetic field, 20, 22, 23, 24, 21. Respective Hall elements with a magnetic sensitivity of at least 350 µV / mT and a temperature coefficient of magnetic sensitivity of not more than 0.05% / ° C are used as magnetic field sensors. Hall elements in blocks filled with an epoxy compound, the thickness of the minimum layer between the case of the magnetic field sensor and the wall of the block body, combining the sensors in the sensor holder and in contact with the transported medium, is 2 mm. Other magnetic field sensors can be used, the selection and connection of which can be carried out by a specialist in this field of technology. When performing a flaw detector with ultrasonic sensors (ultrasonic flaw detector), ultrasonic sensors are installed in the sensor holders. The type of sensors and their orientation are determined by the tasks being solved. For thickness measurement purposes, ultrasonic sensors are mounted so that they emit ultrasonic waves perpendicular to the pipe wall; for the purpose of detecting crack-like defects, ultrasonic sensors are installed so that the radiation direction is about 17 degrees normal to the pipe wall. For the purpose of detecting crack-like defects, electromagnetic ultrasonic sensors can also be used, which can excite ultrasonic waves directly in the pipeline wall (electromagnetic-acoustic transducers). s Similarly, other types of non-destructive testing sensors that are sensitive to parameters reflecting the state of the wall of the pipeline under examination can be installed and connected. The structural elements of the in-tube shells that ensure the advancement of the shells inside the pipelines, and the composition of the electronic equipment for performing measurements is well known in the art and the corresponding choice can be made by a person skilled in the art. The device operates as follows. An in-line flaw detector is placed in the pipeline and includes the pumping of gas (oil, oil) through the pipeline. Between the region of the transported medium in front of the flaw detector and the area after the defectoscope, a pressure drop of about 1 atm is established, which sets the flaw detector in motion. For magnetic control of the pipeline wall, magnetic sensors are used (magnetic leakage sensors): when a flaw detector moves through the pipeline using magnets and brushes, the pipeline wall is magnetized to a saturation state and the tangential component of magnetic induction is measured near the inner surface of the pipeline in the magnetized region of the pipeline wall between the brushes using the first pair of belts of the sensor holders 15-19 and the second pair of belts of the sensor holders 20-24, as well as outside the area of magnetization of the walls and - using the third pair (sensor holder belts 25, 26. The measurement data are converted and recorded in the digital data storage of the on-board computer. Measurement of the magnetic field components is made by periodically referring to the magnetic field sensors (by interrogating the sensors). Cracks or defects associated loss of metal (corrosion, risks, seizures), leads to a change in the magnitude and nature of the distribution of magnetic induction, while the measured leakage of the matte flux is a parameter reflecting the state of pipelines. When solving the problem of ultrasonic thickness gauging, ultrasonic sensors are used, ultrasonic pulses are emitted perpendicular to the inner surface of the pipeline. These pulses are partially reflected from the inner wall of the pipeline, from the outer wall of the pipeline or from the area of the defect, for example, delamination of the metal in the pipe wall. Partially ultrasonic pulses pass through the boundary of the media formed by the outer wall of the pipeline. After emitting ultrasonic pulses, the ultrasonic sensors switch to the reception of reflected pulses and receive pulses reflected from the inner surface of the wall, pulses reflected from the outer surface of the pipe wall, or pulses reflected from the indicated area of the wall defect. Moreover, the wall thickness of the pipe, which is measured using ultrasonic sensors, is a parameter that reflects the state of the pipe wall. In order to detect cracks in the wall of the pipeline, ultrasonic pulses emit at an angle of about 17 ° -19 ° to the normal to the inner surface of the pipeline. These pulses are partially reflected from the inner wall of the pipeline, from the outer wall of the pipeline or from a crack-like defect. Partially ultrasonic pulses pass through the boundaries of the media or are reflected, weakening the useful reflected pulse. After the emission of ultrasonic pulses, the ultrasonic sensors switch to the reception mode of the reflected pulses and receive pulses reflected from the crack-like defect. h The received digital data on the time intervals corresponding to the travel time of the ultrasonic pulses and the pulse amplitudes are converted and recorded in the digital data storage device of the on-board computer. In this case, the value of the number of pulses reflected from crack-like defects is a parameter reflecting the state of the pipeline. Another parameter reflecting the state of the pipeline is the amplitude of the pulse reflected from the crack-like defect and characterizing the depth of the defect in the pipe wall. Similarly, in-pipe inspection is carried out by periodically starting and / or interrogating sensors of a different type (magneto-optical, optical, electromagnetic-acoustic, sensors of the cross-sectional profile of the pipeline). If, during its movement inside the pipeline, the flaw detector encounters significant narrowing in the cross section, for example, of a not fully open slide gate valve, the polymer elements (lining) 58 of FIGS. 2, 66, 67 of FIG. 4, when faced with a significant obstacle, experience bending in the plane, passing through the axis of symmetry of the flaw detector, in the direction of its tail, absorb shock of the lever, protect the sensors from damage and allow you to keep the control sensors and their mount in working condition and continue execution from measurements during and after the flaw detector passes through a section of a narrowing or an obstacle, which avoids data loss in such sections or obtaining data that does not allow identifying defects in the pipeline wall. Upon completion of the control of a given section of the pipeline, the flaw detector is removed from the pipeline and the data accumulated during the examination are transferred to a computer outside the flaw detector. s Subsequent analysis of the recorded data allows us to conclude that there are defects and determine their size. Algorithms for interpreting data in non-destructive testing methods to identify defects are well known in the art. The obtained data on defects in the wall of the pipeline make it possible to calculate the strength of the pipeline and, if necessary, determine the safe pressure for pumping the product through the examined pipeline. Another example implementation of the claimed invention is an in-line flaw detector, section 71 of which is shown in FIG. 5. The flaw detector, which is passed inside the examined pipeline, contains a housing 72, control sensors (non-destructive testing sensors) installed on the housing, which are sensitive to parameters reflecting the state of the pipeline wall, some of which are indicated by numbers 73-76 in Fig. 5. The defectoscope also contains the means for taking measurements and processing the measurement data, located in the corps 72 of the flaw detector. The control sensors are fixed in the sensor holders mounted on the flaw detector housing 72 around the perimeter around the axis of symmetry of the defect detector. Each sensor holder of Fig. 7 contains five runners 88 that can slide along the inner surface of the pipeline, in each run 88 of Fig. 6, (96, 97 of Fig. 8, respectively), control sensors are installed. Each sensor holder contains an elastic link 81 of FIG. 6, FIG. 7, made in the form of a plate of polymer material, on the peripheral end of which is attached a peripheral elastic link 83, made in the form of an elastic metal plate. At the same time, the end of the metal end nearest to the axis of the flaw detector is fixed at the peripheral end of the polymer elastic link 81

elastic link 83, - more distant from the axis of symmetry of the defectoscope, and a runway 88 is fixed at the peripheral end of the peripheral metal elastic link 83. The planes of the plates lie in planes perpendicular to the plane passing through the symmetry axis of the flaw detector. The polymer elastic link 81 has an flexural stiffness in the plane passing through the symmetry axis of the flaw detector that is greater than the metal elastic link 83 (i.e., at equal moments of forces applied to the elastic links, the metal elastic link 83 experiences a greater angular deviation during bending, than polymer elastic link 81).

In the embodiment illustrated in FIG. 8, the spring elements 98 and 99 are made capable of abutting the runners 96 and 97, respectively, from the symmetry axis of the flaw detector and pressing said runners against the inner surface of the pipeline. The bending stiffness of the peripheral elastic links 94, 95 in a plane passing through the flaw axis of symmetry of the flaw detector is less than the stiffness of the polymer elastic links 92, 93 of the same sensor holder for bending in the specified plane, and the bending stiffness of the metal elastic links 104, 105 in the specified plane. While the peripheral elastic link 94 is pressed against the elastic link 104, on which it is attached, from the tail of the flaw detector; the peripheral elastic link 95 is pressed against the elastic link 105 on which it is attached, from the flaw detector's tail side, the elastic link 93 can also be connected to the elastic link 92 using an elastic (e.g. polymer) link, one end of which is fixed at 102 .8, and the second end is at point 105 (in the general case: one end is fixed at the attachment point of the first elastic link on the defectoscope body, and the second end is fixed at the peripheral end of the elastic link from an adjacent row of elastic links). The length of the first polymer elastic link 92 from the attachment point 102 on the flaw detector body-bracket 91 to the attachment point 103 of the metal elastic link 104 is about 0.15 of the diameter of the cylinder into which the flaw detector fits. The length of the elastic link 94 from the attachment point x to the elastic link 104 to the attachment point of the runner 96 is about 0.15 of the diameter of the cylinder into which the flaw detector fits. Accordingly, the length of the first polymer elastic link 93 from the attachment point on the flaw detector unit 100 link to the attachment point of the metal elastic link 105 is about 0.15 of the diameter of the cylinder into which the flaw detector fits. The length of the elastic link 95 from the attachment point to the elastic link 105 to the attachment point of the runner 97 is about 0.15 of the diameter of the cylinder into which the flaw detector fits. In this case, the distance between the mounting location of the sensor holder on the flaw detector housing and the mounting location with the sensor holder is about 0.5 distance between the mounting location of the sensor mount on the flaw detector and the contact point of the runner installed in this sensor mount with the inner surface of the pipeline. In a possible embodiment of the flaw detector, each sensor holder from one sensor holder belt is connected by several rigid elements (or one rigid element) to several sensor holders from another sensor holder belt. In another embodiment, each sensor holder can be made as shown in FIG. 6, FIG. 7 and connected by a rigid element to the sensor holder from another belt of sensor holders as shown in FIG. In another embodiment, each sensor holder may be configured as shown in FIG. 8 without connecting a rigid element to any of the adjacent sensor holders. V, in the embodiment shown in FIG. 5, the sensor holders in each pair of rows are staggered, with the sensor holders 73 being in the first belt, the sensor holders 74 in the second belt, the sensor holders 75 in the third belt, holders 76 with sensors belong to the fourth zone. The length of the first polymeric elastic link from the attachment point on the flaw detector element to the attachment point of the metallic elastic link can be about 0.1 of the diameter of the cylinder into which the flaw detector fits, the length of the second elastic link from the attachment point to the first elastic link to the runner attachment point may be about 0.05 of the diameter of the cylinder into which the flaw detector fits. In this case, the distance between the mounting location of the sensor holder on the flaw detector housing and the mounting location with another sensor mount is about 0.7 distance between the mounting location of the sensor mount on the flaw detector housing and the contact point of the runner installed in this sensor mount with the inner surface of the pipeline. In another embodiment, the length of the first polymer elastic link from the attachment point on the flaw detector housing element to the attachment point of the metal elastic link can be about 0.3 of the cylinder diameter into which the flaw detector fits, the length of the second elastic link from the attachment point to the first elastic link to the place fastening the runner can be about 0.2 of the diameter of the cylinder into which the flaw detector fits.

When implementing a flaw detector with magnetic sensors {magnetic flaw detector) at positions 77, 78 of FIG. 5, magnets with ferromagnetic brushes mounted on them can be mounted on the flaw detector body, which can contact the inner surface of the pipeline. In this case, a closed loop of the magnetic flux is formed: magnets with brushes in position 78 - ferromagnetic wall of the pipeline - magnets with brushes in position 77 - ferromagnetic flaw detector body - magnets with brushes in position 78. Magnetic field sensors mounted on the flaw detector body in the form of a magnetic flaw detector are Sensors that are sensitive to diagnostic parameters that reflect the state of the pipeline wall, namely: leakage of magnetic flux in areas of crack-like and corrosion defects in the pipeline wall Oh yeah. The magnetic field sensors are installed in the slider of the sensor holders, with several magnetic field sensors installed in each runner of the sensor holder. Integrated Hall elements with a magnetic sensitivity of at least 350 μV / mT and a temperature coefficient of magnetic sensitivity of no more than 0.05% / ° C are used as magnetic field sensors in the presented implemented embodiment. Hall elements are filled in blocks with an epoxy compound, the thickness of the minimum layer between the case of the magnetic field sensor and the wall of the case of the block containing several sensors and in contact with the transported medium is about 2 mm.

When performing a defectoscope with ultrasonic sensors (ultrasonic flaw detector), ultrasonic sensors are installed in runners 96, 97 or 88. The type of sensors and their orientation are determined by the tasks being solved. For thickness measurement purposes, ultrasonic sensors are installed so that they emit ultrasonic waves perpendicular to the pipe wall; for the purpose of detecting crack-like defects, ultrasonic sensors are installed so that the radiation direction is about 17 fades normal to the pipe wall. For the purpose of detecting crack-like defects, electromagnetic ultrasonic sensors capable of exciting ultrasonic waves directly in the pipe wall (electromagnetic-acoustic transducers) can also be used.

On the flaw detector housing, a belt of supporting wheels and polymer cuffs can also be installed, which ensure centering of the projectile in the pipeline and its advancement in the pipeline by the flow of the transported medium, as well as a meter of the distance traveled inside the pipeline, for example, based on wheel odometers. The structural elements of the in-tube shells that ensure the advancement of the shells inside the pipelines, and the composition of the electronic equipment for performing measurements is well known in the art and the corresponding choice can be made by a person skilled in the art.

In another possible embodiment, the flaw detector may comprise a section of FIG. 1 and a section of FIG. 5, or one or more sensor holder belts as shown in FIG. 1 and one or more sensor holder belts as shown in FIG. 5.

3 / JJ (ff x The device works as follows. An in-line flaw detector is placed in the pipeline and the gas (oil, oil product) is pumped through the pipeline. A pressure drop of about 1 atm is established between the transported medium in front of the flaw detector and the area after the flaw detector, which sets the flaw detector in motion For magnetic control of the pipe wall, magnetic sensors are used (magnetic leakage sensors): when the flaw detector moves through the pipe, the pipe wall is magnetized using magnets and brushes to the saturation state and the tangential component of the magnetic induction is measured near the inner surface of the pipeline in the coiled area of the pipeline wall between the brushes using the first pair of belt holders of the sensor holders 73, 74, as well as outside the area of magnetization of the wall using the second pair of belt holders of the sensors 75, 76. The measurement data are processed and recorded in the drive of the on-board computer.The magnetization of the wall of the pipeline occurs within the zone of location of the sensor holders 73, 74, located between the ferromagnetic wire brushes, and in the same area are the sensor holders 73, 74. Magnetization is carried out using permanent magnets mounted under the brushes. Measurement of the components of the magnetic field is done by periodically accessing the magnetic field sensors (by interrogating the sensors). The presence of cracks or defects associated with the loss of metal (corrosion, scoring) leads to a change in the magnitude and nature of the distribution of magnetic induction. Moreover, the measured magnitude of the leakage of magnetic flux is a parameter that reflects the state of the pipeline. h When solving the problem of ultrasonic thickness measurement, ultrasonic sensors are used, ultrasonic pulses are emitted perpendicular to the inner surface of the pipeline. These pulses are partially reflected from the inner wall of the pipeline, from the outer wall of the pipeline or from the area of the defect, for example, delamination of the metal in the pipe wall. Partially ultrasonic pulses pass through the boundary of the media formed by the outer wall of the pipeline. After emitting ultrasonic pulses, the ultrasonic sensors switch to the reception of reflected pulses and receive pulses reflected from the inner wall, pulses reflected from the outer wall of the pipe, or pulses reflected from the indicated area of the wall defect. Moreover, the wall thickness of the pipe, which is measured using ultrasonic sensors, is a parameter that reflects the state of the pipe wall. In order to detect cracks in the wall of the pipeline, ultrasonic pulses emit at an angle of about 17 ° -19 ° to the normal to the inner surface of the pipeline. These pulses are partially reflected from the inner wall of the pipeline, from the outer wall of the pipeline or from a crack-like defect. Partially ultrasonic pulses pass through the boundaries of the media or are reflected, weakening the useful reflected pulse. After the emission of ultrasonic pulses, the ultrasonic sensors switch to the reception mode of the reflected pulses and receive pulses reflected from the crack-like defect. The obtained digital data on the time intervals corresponding to the travel time of the ultrasonic pulses and the pulse amplitudes are converted and recorded in the digital data storage device of the on-board computer. In this case, the value of the number of pulses reflected from h crack-like defects is a parameter reflecting the state of the pipeline. Another parameter reflecting the state of the pipeline is the amplitude of the pulse reflected from the crack-like defect and characterizing the depth of the defect in the pipe wall. Similarly, in-pipe inspection is carried out by periodically starting and / or interrogating sensors of a different type (magneto-optical, optical, electromagnetic-acoustic, sensors of the cross-sectional profile of the pipeline). If, during its movement inside the pipeline, the flaw detector encounters significant narrowing in the cross section, for example, with an incompletely open slide gate valve, the elastic polymer links 81 or 92, 93, respectively, are bent, protecting the magnetic field sensors from damage and allowing the control sensors and their fastening to be kept operational condition and continue to perform measurements after passing through the flaw detector section of the narrowing or obstacles. If the obstacles are insignificant (properly installed underlay rings, insignificant dents in the pipe wall), that is, the harater size of the obstacle is less than the characteristic length of the link 83 or links 94, 95, respectively, then these links experience a bend in the plane passing through the symmetry axis of the flaw detector, in the direction its tail, while the runners 88 or runners 96, 97, respectively, maintain parallelism between their outer surface and the inner surface of the pipeline, thereby avoiding data loss x sections or obtaining data that does not allow to identify defects in the wall of the pipeline. , Upon completion of the control of a given section of the pipeline, the flaw detector is removed from the pipeline and the data accumulated during the diagnostic process are transferred to a computer outside the flaw detector. Subsequent analysis of the recorded data allows us to conclude that there are defects and determine their size. Algorithms for interpreting data in non-destructive testing methods to identify defects are well known in the art. The obtained data on defects in the wall of the pipeline make it possible to calculate the strength of the pipeline and, if necessary, determine the safe pressure for pumping the product through the examined pipeline.
