Definitions
- the invention relates to a pig for use in a pipeline to determine the material of the pipeline in the context of an inline inspection.
- the pig has a position determination unit, via which the position of the pig in the pipeline can be determined, and at least one braking arrangement for fixing the pig in a certain position in the pipeline, as well as an X-ray fluorescence sensor and / or an atomic emission spectroscopy arrangement (AES arrangement) , especially for performing laser-induced plasma spectroscopy (LIBS).
- AES arrangement atomic emission spectroscopy arrangement
- the material of a pipeline or a section of a pipeline can be determined using an X-ray fluorescence sensor and / or an AES arrangement.
- An X-ray fluorescence analysis and / or by means of atom emission spectroscopy can thus be used to check which steel was used in a section of a pipeline, in particular a pipeline. This is not only interesting for old pipelines, but also for new pipelines. It is checked whether the documentation is correct and the pipeline installation can be accepted. This is of particular interest for pipelines that transport natural gas and / or oil or oil products.
- a pig according to the invention has at least one position determination unit with which the position of the pig in the pipeline can be determined and at least one brake arrangement for fixing the pig at a specific position in the pipeline. A pig according to the invention can thus be stopped in a specific position in the pipeline. An X-ray fluorescence analysis and / or atomic emission spectroscopy can then be carried out.
- a pig according to the invention also includes the devices necessary for operation, such as control electronics, via which the electronic components arranged on the pig can be controlled, a data memory for at least temporary storage of measurement data from the X-ray fluorescence sensor and / or the AES arrangement, as well as means for output and / or exchange of data.
- the pig can have an evaluation unit for evaluating sensor data, in particular data from the position determining unit.
- the pig thus has the usual components of electronic data processing such as memory and central processing unit.
- the pig also has an energy storage device via which electrical energy is made available to the electrical and / or electronic components of the pig.
- the position determining unit preferably comprises an odometer, a
- weld detection arrangement and / or a signal receiver for through the Positioning signals sent to the pipe wall With an odometer, the position can be determined as a function of the distance covered. With a weld seam detection arrangement, the weld seams can be identified and, if necessary, counted.
- the weld seams to be recognized are weld seams arranged circumferentially in the pipeline wall, with which individual sections of a pipeline are joined. Thus, depending on which of these weld seams are recognized, a new pipe section begins.
- the individual sections with their length and thus also the position of the weld seams are known.
- a pig according to the invention can be stopped after each new circumferential weld seam via a weld detection arrangement and one or more X-ray fluorescence analyzes and / or atomic emission spectroscopy analyzes can thus be carried out in each pipe section.
- the position determination unit can also comprise a signal receiver for positioning signals sent through the pipe wall. These signals can be brought in by reference transmitters attached to the outside of the pipeline. The pig can determine its position in the pipeline using the signal brought in by the reference transmitter.
- the positioning signal can also include a command to stop the pig. In this case, the pig is stopped when the corresponding signal can be received with sufficient strength or a corresponding signal is sent into the pipeline or through the pipeline wall at a certain point in time.
- the pig preferably has a cleaning arrangement for cleaning a section of the pipeline wall to be analyzed by means of the X-ray fluorescence sensor and / or the AES arrangement.
- the pipeline wall is wrestled from deposits or rust is removed. An analysis of the material composition is therefore not impaired by such contamination of the pipeline.
- the cleaning arrangement can for example comprise a rotating wire brush which is guided over the section of the pipe wall to be analyzed.
- the pig preferably has a drive unit for positioning the pig within the pipeline.
- a pig is usually moved through the pipeline by the medium flowing in the pipeline.
- the use of a drive unit enables the pig to be positioned independently of the flow of the fluid in the pipeline.
- the use of a drive unit improves the ability of the pig to be positioned in the pipeline. Sections of the pipeline wall to be analyzed can be approached in a targeted manner.
- the pig preferably has a bypass system with a bypass valve, through which a fluid flowing in the pipeline can be conducted past the pig or through the pig.
- a bypass system reduces the forces to be applied by the brake arrangement, which act on the pipeline.
- the fluid flowing through the pipeline can pass the specified pig.
- the flow of the fluid flowing in the pipeline therefore does not have to be switched off during the measurement.
- a reduction in the flow rate or the pressure in the pipeline is sufficient. Possibly is an adjustment of the flow in the pipeline is also completely unnecessary.
- a bypass system with a bypass valve can also be used to position the pig inside the pipeline.
- the pig with the bypass valve closed or the bypass system closed can be transported by the fluid flowing in the pipeline into the vicinity of the pipeline section to be examined.
- the bypass valve is then opened so that part of the fluid flowing in the pipeline can pass the pig or pass through the pig.
- the pig can be fixed by the brake arrangement. After the measurement, the brake arrangement can release the pig again, whereupon the pig is transported further in the pipeline by the fluid flow. This can be intensified by at least partially closing the bypass valve.
- the bypass valve is particularly preferably designed such that a fluid flowing in the pipe acts on the bypass valve with a force that moves the bypass valve in the direction of a closed position.
- the bypass valve is moved by a motor.
- the bypass valve is particularly preferably pivotable about a pivot axis, the bypass valve being designed asymmetrically about the pivot axis.
- the bypass valve is arranged on the pig so that the larger area of the bypass valve can be acted upon by a fluid flowing in the pipeline with a force moving the bypass valve in the direction of the closed position.
- This is a particularly simple embodiment of a bypass valve that closes automatically under the action of the fluid flowing in the pipeline. Such a bypass valve can ensure that the pig is discharged from the pipeline even in the event of malfunctions.
- the pig advantageously has an energy converter which is set up to convert the kinetic energy of the fluid flowing in the pipeline into electrical energy.
- an energy converter can comprise a generator unit which is connected to a propeller, where the propeller is set up to be set in rotation by the fluid flowing in the pipeline.
- Such an energy converter is particularly advantageous for a pig with an X-ray fluorescence sensor and / or an AES arrangement, since such a pig remains in a pipeline for a long time in comparison to conventional inspection pigs and has to be decelerated and accelerated several times and since an X-ray fluorescence sensor and / or an AES arrangement has an increased energy requirement compared to the measurement sensors usually used in inline inspection.
- the pig preferably has several X-ray fluorescence sensors and / or AES arrangements for the simultaneous determination of the pipeline composition at several points. By measuring at several points in the pipeline, the detection of the material used in the corresponding pipeline section is more reliable.
- the X-ray fluorescence measurements and / or AES measurements in particular in the form of LIBS measurements, can be falsified by impurities or deposits. The result is improved by determining in several places.
- a proximity sensor is preferably arranged on the X-ray fluorescence sensor, the proximity sensor being set up to prevent the X-ray fluorescence sensor from being switched on if the proximity sensor is not in contact with a pipe wall.
- An X-ray fluorescence sensor irradiates the section of a material sample to be examined with short-wave X-rays.
- a proximity sensor arranged on the X-ray fluorescence sensor ensures that the X-ray radiation is not inadvertently emitted during transport or while a corresponding pig is being introduced into a pipeline and personnel are endangered. At least two proximity sensors are particularly preferably arranged on an X-ray fluorescence sensor.
- the proximity sensors are set up in such a way that switching on the X-ray fluorescence sensor is prevented as long as not all proximity sensors are in contact with a pipe wall. Using several proximity sensors increases the security against accidental activation of the X-ray fluorescence sensor.
- the pig preferably has at least one first sealing element arranged adjacent to a first end of the pig body and at least one second sealing element arranged adjacent to a second end of the pig body.
- the sealing elements are spaced apart and can be brought into contact with an inner pipe wall of the pipeline.
- the X-ray fluorescence sensor is arranged between the first and the second sealing element. As a result, a space can be provided between the two sealing elements in which conditions prevail which are necessary for the use of an X-ray fluorescence sensor.
- the sealing element is elastic and has an annular cavity which can be filled with a fluid and via which the sealing element can be acted upon by a force moving the sealing element outward in the radial direction.
- the annular cavity can be formed by the device element itself.
- the sealing element can, however, also have an annular elastic hollow body which forms the annular cavity.
- a correspondingly designed sealing element can thus be brought into contact with a pipeline wall by filling the cavity with a fluid, or the force exerted by the sealing element on the pipeline wall can be increased will.
- Such a sealing element can, for example, also be part of the brake arrangement in which braking takes place by pressing the sealing element against the inner wall of the pipe. By using several such sealing elements, the frictional forces can be increased further.
- Such a pig can have means for pumping empty the area between the first and the second sealing element in order to improve the conditions there for inspection of the pipeline.
- the internal pressure in the pipeline or the pressure difference across the bypass of the repair tower pig arranged in the pipeline can be used to support the pumping process.
- a Venturi nozzle in particular can be used in the bypass for this purpose.
- the pig further particularly preferably has a container with a flushing fluid, in particular a pressurized gas, with which the area between the first and the second sealing element can be flushed.
- the pig furthermore has at least one flushing valve which is arranged in the pig body and / or in at least one of the sealing elements. Any medium located between the first and the second sealing element is at least partially displaced from this space.
- the rinsing fluid is selected in such a way that the X-ray fluorescence sensor carries out particularly reliable measurements in the rinsing fluid.
- the invention also relates to a method for inline inspection of a pipeline to determine the material composition of the pipeline in which a pig is introduced into a pipeline with an X-ray fluorescence sensor and / or an AES arrangement, the pig is passed through the pipeline and braked in the pipeline, in particular brought to a stop. Then an X-ray fluorescence measurement and / or AES measurement is carried out on the inside of the pipeline.
- the composition of the pipe inner wall can thus be determined without the pipe having to be made accessible from the outside.
- the method preferably comprises the implementation of several measurements in a pipeline, in particular in each new pipeline section.
- the pig is transported further through the pipeline and brought to a stop at another point within the pipeline, at which another measurement is made. These process steps are repeated many times if necessary. This allows large sections of a pipeline or the entire pipeline to be examined by means of a corresponding pig. The inspection work can thus be carried out inside the pipeline and it is not necessary for people to leave a pipeline and have it examined.
- a section to be analyzed by means of the X-ray fluorescence sensor and / or the AES arrangement is preferably cleaned before a measurement is carried out. This removes deposits or dirt from the surface of the inner wall of the pipe, which could falsify the measurement.
- the cleaning can, for example, be carried out by a cleaning arrangement, for example comprising brushes, attached to the pig. But cleaning can also be done by a cleaning pig, which is sent through the pipeline in front of the pig with the X-ray fluorescence sensor and / or the AES arrangement.
- a fluid flowing in the pipeline is preferably passed through a bypass of the pig.
- the fluid can continue to be transported in a pipeline to be examined while the method is being carried out, while the pig is in place.
- the operation of the pipeline can be maintained or is only partially restricted. This also reduces the cost of performing the method.
- FIG. 1 shows a pig according to the invention.
- FIG. 1 shows a pig 2 in a pipeline 4.
- An X-ray fluorescence sensor 10 is arranged on the pig 2.
- the X-ray fluorescence sensor 10 is fixed on a pivotable arm which moves from a transport position, shown in dashed lines, at which it rests against a pig body 3 of the pig, and a measurement position in which the X-ray fluorescence sensor 10 rests the pipeline 4 is applied, can be moved.
- Two proximity sensors 16 are arranged adjacent to the X-ray fluorescence sensor 10. These sensors 10, 16 are brought together in a sensor holder. In a measuring position, the proximity sensors 16 are in contact with the pipeline 4.
- the proximity sensors 16 are designed in such a way that the X-ray fluorescence sensor 10 with the source for high-energy X-ray radiation present there can only be activated when the proximity sensors 16 are in contact with an object to be measured, in this case the pipeline 4.
- a cleaning arrangement 22 is arranged on the pivotable arrangement. In the present case, this is designed as a brush that can be set in rotation and has a drive. The brush can be designed as a wire brush with steel bristles or polymer bristles.
- the cleaning arrangement 22 can, however, also be implemented with other alternative cleaning agents. These can be nozzles that apply a cleaning fluid to the section to be examined and / or blow the section free with a gas stream. Facilities that wipe the section or suction are also conceivable.
- the cleaning arrangement 22 is used to free a section of the pipe 4, on which a measurement by the X-ray fluorescence sensor 10 is to take place, from deposits and / or impurities.
- the pig 2 has a position determining unit 6 which is designed in the form of a weld seam detector.
- the weld seam detector detects circumferential weld seams with which individual sections of a pipe line are connected.
- the pig 2 can thus initiate a measurement by the X-ray fluorescence sensor 10 after each detection of a circumferential weld seam by means of the position determination unit 6.
- each segment is analyzed at least once one after the other when the pipeline is passed through and the steel quality used there is determined. It is also conceivable to carry out several measurements in each section, which are carried out in sections spaced from one another.
- a position determination unit 6 can have an odometer and / or a sensor for signals sent through the pipeline 4.
- the pig in the exemplary embodiment according to FIG. 1 must be able to stop in the pipeline.
- the measurement by means of the X-ray fluorescence sensor 10 has an increased measurement duration, during which the X-ray fluorescence sensor 10 must remain at a point on the pipeline to be analyzed.
- the pig has a bypass system 12 with a bypass valve 14.
- the pig body 3 has one or more continuous cavities 4 extending in the longitudinal direction through the pig body 3, through which a fluid located in the pipeline 4 can pass through the pig body 3. This cavity or cavities can be closed via a bypass valve 14.
- the bypass valve 14 closes the cavities while the pig 2 is to be transported through the pipeline.
- the bypass valve 14 is opened.
- the bypass valve 14 is embodied here with a round cross section and can be pivoted about a pivot axis, the pivot axis being arranged asymmetrically on the valve body of the bypass valve 14. This ensures that the bypass valve 14 closes automatically under the action of a fluid flowing in the pipeline 4.
- the bypass valve 14 is normally motorized geöff net and closed. If the drive of the bypass valve 14 fails, the bypass valve 14 is brought into a closed position by the fluid flowing in the pipeline 4 and the pig 2 is discharged from the pipeline.
- the pig 2 also has a brake arrangement 8.
- this comprises a sealing element 18 which has an annular cavity 20.
- the brake arrangement 8 comprises a hydraulic pump with which the annular cavity 20 of the sealing element 18 can be filled with a fluid.
- the sealing element 18 is brought into contact with the pipeline 4 and / or the pressure that the Dichtungsele element 18 exerts on the pipeline 4 is adjusted.
- the pig 2 is thus braked in the pipeline 4 and set at a point at which the X-ray fluorescence sensor 10 can perform a measurement.
- Alternative configurations of the sealing element are conceivable.
- a brake arrangement 8 can, however, also comprise movable brake elements that can be brought into contact with the pipeline 4 and / or comprise drive elements through which the pig 2 passes through the pipeline. device 4 is transported. These can be fluid drives such as propellers, impellers or jet drives or wheels or track chains in contact with the pipeline 4. These can move the pig 2 through the pipeline 4, but also stop it at a certain point in the pipeline. For this purpose, the wheels or crawlers can have brakes.
- the pig 2 can also have an AES arrangement for carrying out atomic emission spectroscopy, in particular a LIBS arrangement for carrying out laser-induced plasma spectroscopy.
