Definitions

  • This invention relates to the field of high-pressure tanks that are reinforced on the exterior by high strength helical deployed metal wires.
  • a number of methods have been patented or is generally known for the manufacture of high pressure tanks that are comprised by an inner metal shell fluid barrier reinforced on the outside by helical deployed metal wires .
  • the ultimate tensile strength that can be economically obtained m industrial production is approximately 2.5 times higher m the wires than m the fluid barrier material .
  • a particular problem is the termination of the metal wires at the ends of the pressure vessel .
  • Welding is a convenient method of securing the wires at the ends.
  • the heat of the welding process affects the strength properties particularly of the carbon steel wires thereby causing a reduction m strength m the heat-affected zone.
  • the wires often attain their high strength by cold drawing, with the result that they are subject to strength reduction in heat treatment processes .
  • a separate problem is the welding of the wires to the fluid barrier metal. Annealing of such welds may be required to reduce stress concentrations in the weld zone. Such annealing however has a negative effect on the strength of the wires in the annealed zone.
  • the present invention is particularly directed to the placing multiple high strength carbon steel wires on the outside of circular cylindrical metal pressure vessels for reinforcement .
  • the invention teaches a method of securing the carbon steel wires to the pressure vessel by welding in such a way that the full ultimate strength of the wire may be employed in containing the pressure.
  • This aim is achieved by welding the wire to extension pieces to the pressure vessels that are placed concentrically on the longitudinal axis of the pressure vessel . Because these extension pieces are not subject to the internal pressure of the pressure vessel the strain excursions are much reduced compared to those of the pressure vessel . Consequently the helical wires are not stressed as much in this area.
  • An arbitrarily low stress may be achieved at the weld by the simple process of winding a sufficient number of turns on the extension piece such that the friction between the wires and the extension piece resists the tensile stress gradient m the wire.
  • a design that can use the full ultimate tensile strength of both the wires and the parent metal m the fluid barrier may be achieved by making the extension pieces sufficiently long.
  • the invention also teaches the avoidance of heating the parent metal m the fluid barrier thereby avoiding the associated stress concentrations.
  • the invention also teaches a method of continuous production of numerous pressure vessels m a series by temporarily joining them m a contmuos pipe like string prior to being wrapped with wire with subsequent separation and wire welding.
  • the wrapping of numerous pressure vessels m sequence m one operation secures the wrapping of all wires evenly. This avoids a manor problem of starting and terminating the wires with an even lay and under even stress .
  • the start of the wire wrapping and the termination will both take place on short throwaway pieces.
  • This continuous process greatly lowers the cost of manufacturing wire wrapped pressure vessels because many units may share the cost of the throwaway pieces.
  • Figure 1 shows a first embodiment of the invention m which fairly long end pieces attached to the pressure vessel ensures low stress at the wire welds
  • Figure 2 shows a second embodiment m which the wall thickness m the pressure vessel is increased at the ends to enable short end pieces .
  • Figure 3 shows schematically an assembly line for continuous production of multiple pressure vessels.
  • Figure 4 shows the wire winding process .
  • Figure 5 shows the method of joining numerous pressure vessels in one continuous string for wrapping.
  • Figure 6 shows the cutting apart of the wrapped pressure vessels and the securing of the wires at the ends.
  • Figure 7 shows a second embodiment of the wire winding process .
  • Figure 1 shows the end of a cylindrical pressure vessel 10 in a partial cut view.
  • the pressure vessel 10 is fitted with an end cap 11 which may be hemispherical (not shown) or ellipsoidal or any other suitable shape for containing the pressure in the pressure vessel 10.
  • the pressure vessel 10 is comprised of a thin walled part 12 that is usually almost the full length of the vessel 10.
  • the part 12 is joined at the weld 15 to the end cap 11.
  • the end cap 11 is comprised of a cylindrical part 16 having a section 13 with a tapered wall thickness to avoid stress concentrations and a part 14 with constant wall thickness.
  • the part 14 usually has the same wall thickness as the end cap 11.
  • the wall thickness of end cap 11 is higher than the thickness of the cylindrical part 12 because two counterwound metal wire layers 20 and 21 reinforce the part 12 on the exterior thereby reducing the required wall thickness.
  • the layers 20 and 21 typically are comprised of numerous individual wires 22 and 23, not all of which are shown for clarity. Typically the individual wires 22 or 23 are closely spaced m such a manner that the gap between the wires are usually 5 to 10% of the width or diameter of the wires.
  • a typical pressure vessel according to this invention would have a diameter between 250 mm and 1000 mm.
  • a typical number of individual wires 22 or 23 would typically be between 30 and 150 m each layer 20 or 21.
  • the wires 22 and 23 are terminated on an end piece 30 that is fitted to the pressure vessel 10 through the compression joint 31.
  • the end piece 30 is a cylinder having either the same or nearly the same outside diameter as the part 12 and the end cap 11.
  • the wires 22 and 23 are welded to the end piece 30 at welds 25 and 26 respectively.
  • the wires 22 and 23 are placed under stress on the exterior of cylinders 12, 14, and 30. Consequently the end piece 30 is held securely to the end cap 11.
  • the fluid barrier of pressure vessel 10 is completed before placing wires 22 and 23 on the outside of pressure vessel 10. Thus all annealing and other heat treatment may be completed prior to placing of wires 22 and 23.
  • the welding of wires 22 and 23 at welds 25 and 26 takes place on the end piece 30 remote from the pressure vessel 10. Thus the heat generated m welding welds 25 and 26 does not affect the end cap 11 or the part 12.
  • wires 22 rest directly on the end piece 30 whereas the wires 23 rest on the wires 22. Any attempt to stress the material m end piece 30 without the corresponding stressing of wire 22 results in friction between the material m end piece 30 and the wires 22. Consequently by making end piece 30 sufficiently long any desired ratio between the stress m wire 22 at the weld 25 and the stress in wire 22 on the part 12 can be achieved and maintained through the friction between wire 22 and the end piece 30. It is thus feasible to utilize the full ultimate strength of the wire 22 and 23 in the design of the pressure vessel 10 even though their strengths are reduced in the heat affected zone in the vicinity of welds 25 and 26. Likewise it is also feasible to use the full ultimate strengths of the materials used for end caps 11 and part 12 of pressure vessel 10 that are allowed following welding and possible heat treatment.
  • the shape of the wires 22 and 23 are shown as rectangular prismatic on figure 1. However, the shape of the wires 22 and 23 may be any prismatic shape including circular and square. Wires 22 and 23 are often of the rectangular prismatic shape in order to limit the contact stress between the wires 22 and 23.
  • wires 23 rest on top of wires 22. Any stress gradient in wires 23 is transferred by friction first to wires 22 and then from wires 22 to the parent material of end piece 30. Because the contact pressure from wires 23 adds to the contact pressure from wires 22 onto end piece 30 the ability to resist friction in the interface between wires 22 and the end piece is increased when wires 23 are wrapped on top. Therefore numerous layers 20 and 21 could be placed on top of each other without having to make end piece 30 significantly longer.
  • the compression fit 31 between end piece 30 and end cap 11 could also be a weld (not shown) . If heat treatment were required for this weld this could be done before the winding of wires 22 and 23 just as for weld 15.
  • the end piece 30 is subject to torque about the longitudinal pressure vessel axis 32.
  • the option of welding joint 31 may be employed, alternatively a male and female notch (not shown) may be employed to prevent rotation of end piece 30 relative to the end cap 11.
  • Figure 2 shows another embodiment in which the end piece 30 shown in figure 1 can be made very short so as to make the overall length of the pressure vessel as short as possible.
  • the part 12 and the end piece 30 are separated by a piece of heavy wall pipe 41 that is capable of resisting the internal pressure without or with partial assistance from the helical layers 20 and 21.
  • the end piece 30 can be made very short possibly below 200 mm in length.
  • Figure 3 shows a continuos manufacturing process for manufacturing pressure vessels as described in the two embodiments illustrated on figures 1 and 2.
  • the process is shown only schematically in figure 3 and in more detail in figures 4, 5, and 6.
  • Wire winding machines 50 and 51 of the type used in the wire rope and cable industries and in the flexible pipe industry are employed to wind on the helical wire layers 20 and 21 onto pressure vessel 10.
  • the two wire winding machines 50 and 51 will place approximately the same number of wires but in opposite directions so as to achieve a pressure vessel with negligible torque in the fluid barrier (not shown) .
  • Upstream from winding machine 50 unfinished pressure vessels 10 are joined at station 57 by temporary welding at the end pieces 30 into a continuous string of pressure vessels 54.
  • the manufacturing line may be equipped with a pushing/pulling machine 52 referred to in the industry as a caterpuller to move the pressure vessel string 54 through the wire winding machines 50 and 51 against the pull of the wires (not shown) .
  • the push/pull machines 52 push or pull the string of pressure vessels through the winding machines 50 and 51.
  • the push/pull machines are coupled in a known manner through a servo mechanism 55 to the winding machines 50 and 51 such that the advance of the string of pressure vessels 54 is coupled to the rotation of winding machines 50 and 51 to lay down wires evenly on the string of pressure vessels 54 with a constant lay angle (not shown) .
  • the string of pressure vessels 54 is separated at a station 58 downstream from machines 50,51, and 52 after being wound with wires (not shown) in winding machines 50 and 51. This separation takes place through cutting following the welding of the wires to the end piece 30. This process is detailed in figure 6. Following the cutting apart finished pressure vessels 59 may be removed .
  • first and last pieces in the string of pressure vessels 54.
  • These first and last pieces consist of pipe with the same outside diameter as the pressure vessels 10.
  • the wires (not shown) may be fastened by any convenient method to the first piece (not shown) such that an even lay is achieved by the time the wires (not shown) reach the first pressure vessel 10 m string 54.
  • a trailing pipe (not shown) is welded into string 54.
  • These first and last pieces (not shown) may be discarded as scrap or may be cleaned of the wires (not shown) for reuse.
  • FIG. 4 shows the winding process performed by machines 50 or 51. Ordinarily these machines 50 and 51 will make opposite lays rotating m opposite directions. The technology for winding the wires is well known and is only illustrated here to clarify the process covered by the invention.
  • the winding machine 50 has a rotating cage 61 supported on wheels or flanges 60 rotating about and concentric with a center tube 67 through which the string of pressure vessels 54 is fed.
  • the cage 61 holds numerous wire bobbins 62, only one of which is shown for clarity, that pay out the wire 64 through the downstream guide 63 of the rotating cage onto the string 54 of pressure vessels.
  • the bobbin 62 may include a brake (not shown) such that the wire 64 is paid out under a given constant tension.
  • the cage is shown supported on bearings 65 and is driven by a motor 66 which for example can be an electrical motor controlled by the servo mechanism 55 m Figure 3.
  • Figure 5 shows the joining of the individual pressure vessels 10 into a continuous string 54 at station 57 shown on Figure 3.
  • the end pieces 30 have been welded to the pressure vessel 10 m an earlier manufacturing stage.
  • the end pieces 30 are shown with indentations 70 that following the making of the weld 71 to join the two pressure vessels become slots m the continuous assembly 54. These slots 70 are placed to facilitate the cutting apart the string 54 following the winding of the wires (not shown) .
  • the pressure vessels 10 may be moved m several known ways including on rollers 72 for joining and lining up. Following the lining up the weld 71 is made . Most known welding processes may be used to make the weld 71.
  • An alternative way to join the pressure vessels 10 would be to furnish each vessel 10 with a double end piece (not shown) already having the slots 70 and to join the pieces 10 through the welding of one of the welds 31.
  • Figure 6 shows the cutting apart at station 58 shown on figure 3 of string 54 into individual pressure vessels 10.
  • the wires 22 and 23 are ordinarily laid under tension onto vessel 10. Additionally the wires 22 and 23 are usually wound onto the vessel 10 without preforming or stress relief. Consequently the wires 22 and 23 will tend to jump away from the vessel 10 when cut and when welding is attempted. Therefore the wires 22 and 23 are temporarily secured with bands 80 and 81.
  • the bands 80 and 81 are clamped onto end pieces 30 with sufficient force that when the wires 22 and 23 and the end pieces 30 are cut at slots 70 that the wires 22 and 23 remain m place on the end piece 30. Following the cut the wires 22 and 23 may be welded to the end piece 30 through several known methods, whereupon the bands 80 and 81 may be removed .
  • the bands 80 and 81 may include resistance-welding equipment (not shown) .
  • the wires 22 and 23 may be welded before the cutting apart of string 54.
  • Other variations not shown include welding the wires 22 and 23 to the end cap 11 and only use end piece 30 as a spacer to provide for a continuous pressure vessel string 54 during the winding of wires 22 and 23.

  • the pipe 95 is moved through the winding machine m a motion that combines translation m the direction of the longitudinal axis of pipe 95 with simultaneous rotation about the longitudinal axis of the pipe 95.
  • the winding process would involve numerous bobbins 90 and 97, however, only two are shown for clarity.
  • the technology for winding the wires is well known and is only illustrated here to clarify the process covered by the invention.
  • the pipe 95 is fed through the winding machine illustrated by bobbins 90 and 97 by one or more push /pull machines 92.

  • the push/pull machine 92 grips pipe 95 through means not shown and has a mechanism not shown that rotates the pipe 95 as the machine 92 moves along track 93.
  • This motion causes wires 91 and 96 to be laid m a helical shape upon pipe 95.
  • the bobbins 90 and 97 may include a brake (not shown) such that the wires 91 and 96 are paid out under a given constant tension.
  • the winding machine illustrated by bobbins 90 and 97 would ordinarily have bobbins on both sides of pipe 95 as illustrated on figure 7 to limit side forces on pipe 95.
  • the process shown m figure 7 would ordinarily limit the number of wire layers to be placed m each operation to one. This is opposed to the winding process shown m figure 4, which permits the simultaneous placement of numerous layers of wire. Consequently the process shown m figure 7 would ordinarily require one pass of pipe 95 trough the winding machine for each
