Definitions
- ABSTRACT A strip having hooked edges is laterally curved and coiled into a spiral in which the hooked edges of adjacent coils overlap. Just before the coils are overlapped the strip is formed into a helix the turns of which slant in a direction opposite to that of the turns of the helix finally formed so that when adjacent turns are forced into engagement with each other adjacent turns are resiliently biassed toward each other.
- the invention includes apparatus adapted to carry out this method and the tubular member produced thereby.
- FIG/IO SUMMARY OF THE INVENTION This invention relates to a new method of manufacturing tubular articles by helically winding a shaped metallic strip, to the new tubular members produced by 1 this method, and to the apparatus used in carrying out said method.
- lt is the object of the present invention to provide tubular members made by the simple interfitting of shaped metallic strips and which have the characteristic of possessing both great mechanical strength and a substantial flexibility so that the tubular members may be wound up on cores of relatively'small diameter.
- tubular members according to the invention may be advantageously used as' flexible drill pipe in the drilling of oil wells.
- a bit is mounted at the end of a long tubular member having a certain flexibility, and driven either by an electrical motor at the head of the well, and supplied through electrical cables passing down through the tubular member, or by a turbine driven by a fluid such as the mud which is forced under pressure into the flexible tubular member.
- tubular member is flexible makes it possible to roll it up easily on drums of relatively small diameter. This considerably facilitates the operations of sending down and withdrawing tubular members which are always necessary for the maintenance and repair of drilling bits.
- the cylindrical members used for flexible drilling generally comprise an internal tube of plastic material which seals the tubular member against fluids which pass therethrough and provides a smooth inner surface which facilitates the flow of fluids.
- This internal tube must be located inside an equally flexible tubular member which is capable of resisting the substantial mechanical stresses resulting from the high pressures which must prevail inside and outside the tubular member during drilling.
- This flexible tubular member may be made, in accordance with the invention, from a helically coiled shaped metallic strip.
- tubular members according to the invention are then, in the case of flexible drilling tubes, covered by layers of wire wound thereabout, as in the case of cables, to insure the mechanical strength and resistance to tension which are required.
- the present invention proposes to provide tubular members which, while sufficiently flexible, have a substantial mechanical strength so as to be capable of resisting both internal and external pressure. Moreover, the tubular bodies according to the invention may be easily formed directly around the tube which is to constitute a fluid-tight seal.
- tubular members of the type according to the invention from strong shaped steel strips has already been suggested, using strips having the general form of a Z or an S.
- a permanent arcuate deformation is imparted to the strip, so that the edge of the strip which, after manufacture of the tubular member, is outside the tubular member, is longer than the edge of the strip which, after manufacture of the tubular member, is inside thereof.
- This process is characterized by the fact that the strip is given a shape such that it is resiliently biassed against the last-formed turn of the tubular member.
- the shaped strip is given a natural helical shape in a direction opposite to that in which the tubular member is being formed.
- the present invention is also directed to the new article of manufacture which consists of a tubular member made by helically winding a strong, shaped metallic steel strip having an S or Z shaped section in accordance with the foregoing process, said tubular member being principally characterized by an excellent resistance to internal and external pressure, by substantial flexibility which permits it to be wound on cores of relatively small diameter, and a perfectly cylindrical shape which it retains while being bent.
- the present invention also relates to the new article of manufacture which consists of a flexible tube for use in drilling oil wells essentially characterized by the fact that it comprises a strong flexible tubular steel member as above defined.
- the present invention is also directed to a device for carrying out the foregoing process, which device is essentially characterized by the fact that it comprises in combination: means for bringing the shaped metallic strip at a suitable speed into a plane substantially tangent to the tubular member which is being formed; means for imparting a permanent arcuate deformation to said strip, the side of the strip located in the direction in which the tubular member is being formed having a length greater than the other side of the strip; means consisting, for example, of forming fingers for imparting to said strip a helical deformation about a diameter which corresponds substantially to the diameter of the tubular member, thus assuring the engagement of the coil being formed with the coil which has just been formed; means for guiding the tubular member formed in this manner, and means for synchronizing the rotation of the tubular member which has been formed and the arrival of the strip from which the tubular member is to be made.
- the means for imparting an arcuate deformation to the strong steel strip may advantageously consist of a set of rollers bending the strip beyond its elastic limit.
- the means for imparting a helical shape to the strip may advantageously consist of a forming head having a plate mounted through a universal joint on a framework so as to be adjustable in its operating position by swinging it about both a horizontal axis and a vertical axis.
- This plate comprises a central orifice through which the tubular member is formed. About the periphery of this orifice are means such as T shaped notches to which the supports for the various forming fingers may be attached.
- the supports for the forming fingers make it possible to regulate the angular orientation of the fingers with respect to a direction radial to the tubular member and the distance of the fingers from the axis of the tubular member being formed.
- FIG. 1 is a schematic elevational view of a machine for carrying out the process according to the invention
- FIG. 2 is a top plan view of the machine of FIG. 1;
- FIG. 3 is a schematic perspective view showing how the shaped memallic strip is formed into a helix in accordance with the invention
- FIG. 4 is a partial sectional view of an enlarged scale taken through the axis of a tubular member manufactured in accordance with the invention
- FIGS. 5, 7 and 9 are elevational view taken transversely ofthe axis of a tubular member
- FIGS. 6,8 and 10 are corresponding side views taken during various steps of the formation of the tubular member according to the invention
- FIG. 11 is an elevational view taken transversely with respect to the axis of the tubular member, showing the forming fingers and their supports;
- FIG. 12 is a schematic sectional view taken along the line 12-12 ofFIG. 11.
- FIGS. 1 and 2 show the overall layout of a machine for carrying out the process according to the invention.
- these figures show a reel 1 on which a tube of plastic material 2 is wound.
- This tube is intended to constitute the inner lining of the tubular member according to the invention.
- the reel 1 is mounted on a support 3 which rotates about a horizontal axis.
- Another reel 4 carries the tubular member 5 according to the invention and is mounted on a support 6 which also rotates about a horizontal axis.
- the reel 4 is rotated with respect to the support 6 by a motor 7 through a conventional transmission 8, which is schematically shown.
- the shaped high strength steel strip 9 is unwound from a reel 10 rotatably mounted on a stationary support.
- the device for curving the shaped metal strip is shown on the other figures in a more detailed manner.
- the shaped strip 9 is converted into the tubular member 5 which then passes through a traction cage 14 which-rotates about a horizontal axis and comprises driving rollers 15 which engage the tubular member 5 and drive it along an axial path.
- An electric motor 16 drives a shaft 17 through a set of pulleys and belts. This shaft extends the full length of v the machine and controls, through reduction gearing 18 and belts or chains, the horizontal rotation of the support 6. a
- the shaft 17 controls through reduction gearing 21 the rotation of the pairs of rollers 11 which axially advance the strip 9. Finally, the shaft 17 drives the cage 3 through reduction gearing 22.
- the speeds of rotation of the different members which have been described are so determined as to coordinate the speed of rotation of the tubular member 5 and the speed at which the strip 9 advances to form the member 5 in question.
- the device for carrying out the process according to the invention is shown in a more detailed manner on the perspective view of FIG. 3.
- This figure shows the two pairs of rollers 11 which drive the strip 9 at a suitable speed.
- the section of this strip is shown on a larger scale at the left of FIG. 3.
- the rollers 11 have shapes such that the strip 9 is lead flat to the table 24, which is provided with two forming rollers 13.
- rollers 13 The axes of these rollers are mounted so that they turn freely and their positions may be adjusted by screw means 25, which are schematically shown. These rollers 13 cooperate with a third roller 26 designed to turn the strip 9 toward the forming head.
- the forming head which is indicated as a whole by reference numeral 12, consists of a plate 27 mounted by means of a universal joint on a support 28.
- This universal joint mounting permits the plate 27 to pivot on two arms 29 about a horizontal axis 30.
- the plate 27 is attached to the arms 29 by screws 31 seated in arms 29 and passing through semicircular holes 32 in a member fixed to the plate 27.
- This arrangement permits the position of the plate 27 to be easily adjusted by pivoting it about the horizontal axis 30.
- a second adjustment of the plate 27 with respect to a vertical axis results from the fact that the arms 29 are connected to each other by a cross member 33 which is provided with oblong holes 34 through which the bolts 35 which attach the cross member 33 to the base 28 pass.
- cross-member 33 is mounted on bolts 35 between adjustable nuts which make it possible to adjust the height of the plate 27.
- the plate 27 (which, as has already been explained, may be adjusted in all directions) comprises a central hole 36.
- the tubular member 5 which is formed by the strip 9 passes through this hole.
- the plate 27 comprises a groove 37 encircling the orifice 36.
- This groove has a T shaped section and receives the heads of the bolts 38 by-means of which the supports 39 for the forming fingers are attached.
- these supports 39 are four in number, but may be more or less in number.
- Each support is attached to the plate 27 by bolts 38 which pass through elongated orifices of circular shape in the supports 39 so that the latter may be angularly adjusted in a radial plane with respect to the plate.
- supports 39 which carry the forming fingers 40 may be adjusted in an axial direction by threaded rods 40a.
- FIG. 3 also shows that the circular groove 37 communicates with a lateral groove 37a through which the bolts 38 may be introduced.
- FIGS. 11 and 12 are two views showing the forming fingers 40 and the adjacent parts of the machine on a larger scale.
- FIG. 1 1 shows the part of supports 39 for the forming fingers 40.
- FIG. 12 shows schematically in section the tubular member 5 which is being made from a strip which, in the present case has a very schematic S shape, and the profile of the forming finger 40 corresponding to this specific shape of the strip 9.
- FIG. 4 shows in section on a larger scale the upper part of a tubular member according to the invention made from a strip having a different shape.
- the strip 9 has a generally S shape having two hooked edges 9a and 9b which are connected to the main part of the strip 9 by grooved portions 9'a and 9b.
- the formation of the tubular body is such that a hooked edge 9a of a coil engages in the grooved part 9b of the next coil while leaving a little play between the two hooked edges 90 and 9b which engage each other.
- these coils are preferably so formed that the coils have a tendency to press resiliently against each other. It follows that the edge of each coil 9b bears resiliently against the vertical flank of the recess 9'a or 9b of the adjccent coil while It will thus be seen that due to the space 41, which leaves a certain play between the coils, it is possible to impart to the tubular member according to the invention a relatively great flexibility.
- the coils are resiliently urged against each other so that the tubular member according to the invention has a tendency to spontaneously return to its straight form.
- FIGS. 5 and 6 show the first step in the formation of the helical coil according to the invention.
- FIG. 5 is an elevational view transverse to the axis of a tubular member being formed, and shows the profile of the first coil.
- the shaped strip 9 arrives along a straight path 42 after passing through the forming rollers which have imparted a curved shape thereto as may be clearly seen in FIG. 6.
- the forming fingers impose on the part 42 which advances in the direction of the arrow F a resilient curvature at 43, which results in a permanent deformation at 44 corresponding substantially to the diameter of the tubular member which is being manufactured.
- the arcuate deformation which is imparted to the strip 9 is such that the strip is spontaneously helically wound toward the bottom of the FIG. 6 (arrow F1) in the form of a helix having coils which are not connected to each other.
- the part 44 of the strip 9 is caused to cross the first loop formed not below, but above (FIG. 6). This begins the coil which is shown in FIG. 8.
- FIGS. 9 and 10 show the evolution of the formation of the tubular member upwardly and it will be seen that when the member 44 has been passed above the part 42 (FIG. 8), the helical shape which results must necessarily continue to be formed in this direction (FIG. 8, FIG. 10).
- the degree of force by which the different turns of the spiral are urged against each other may be regulated by regulating the directions and magnitudes of the deformations imposed upon the strip.
- tubular members which are made in accordance with the invention have particularly valuable properties for numerous applications, and especially in the case of flexible tubing for use in drilling oil wells.
- the tubular member has the advantage of offering a great resistance to internal and extemal pressures even though being very flexible, which makes it possible to wind the tubular members according to the invention on cores of sufficiently small diameter to make them easy to transport and handle.
- Method of manufacturing a flexible tubular member by coiling a metallic strip having longitudinally extending abutment means into a helix having overlapping turns comprises the steps of imparting an arcuate deformation to said strip such that the edge of said strip which is to be on the outside of the overlapping turns in the completed tubular member is longer than the edge of the strip which is to be on the inside thereof, coiling said strip into a helix in which, when said helix is a axially unstressed, the turn last formed lies on one side of the preceding turn, and stressing said strip by positioning the last-formed turn on'the other side of said preceding turn, with the portion of the of the longitudinal abutment means in each turn contacting a surface on an adjacent turn to resist a return of said strip to its unstressed position.
- Flexible tubular member in the form of a helical coil having overlapping turns made from an arcuate metal strip, one edge of which is longer than the other, said strip comprising longitudinally extending abut- 7 wells.
- Device'for forming a flexible tubular member from a metallic strip of material having longitudinally extending abutment means which comprises in combination, means for leading the strip along a plane substantially parallel to the axis of the tubular member which is to be formed, means for imparting a permanent arcuate deformation to said strip such that the edge of the strip in the direction in which the tubular member is being formed is longer than the other edge of the strip, means for imparting a helical deformation to said strip to form it into a helix having a diameter substantially equal to that of the member being formed, and for engaging the longer edge of the turn being formed with the turn which has just been formed, means for guiding the inbular member thus formed, and means for synchronizing the speed of rotation of the tubular member being formed and the feed of the strip from which the member is to be formed.
- the means for forming the strip into a helix comprises a forming head including a plate mounted on a universal joint so that its position m be adjusted about both a horizontal and a vertical axis.
- the plate comprises a central orifice through which the tubular member is being formed and that the forming fingers are positioned on the periphery of this orifice by supports which are angularly and longitudinally adjustable.
