Definitions

  • the present invention relates to a method of forming metal pipes and relates particularly to forming seamless metal pipes. More particularly, the invention relates to forming pipe of titanium and/or titanium alloys.
  • One method for forming metal pipes involves forming metal plate, and rolling the plate to bring opposite edges together to form a tube . The edges are welded together forming a seam. This technique is not expensive and there is little waste produced.
  • Pipes are typically formed of steel due to its tensile strength which provides pipes with a high band strength . This means that steel pipes are well suited to high pressure applications. Steel is also used due to its low cost relative to other metals and alloys and due to its weldability which makes steel well suited to forming pipes with seams by the method of rolling and welding plates .
  • titanium or titanium alloy is difficult because titanium and titanium alloy has a high affinity for oxygen and readily forms surface oxides. This means that welding titanium or titanium alloy plate to form pipe is difficult because welding must be performed in an inert atmosphere to prevent oxides occurring in the weld seam which will degrade the strength of the weld. If the weld is compromised by oxides, the pipe will not have
  • titanium and titanium alloys have a hexagonal atomic structure and is more difficult to roll into tubes than steel .
  • titanium and titanium alloy pipe by rolling and welding is costly due to the steps required to ensure that the weld seam is free of oxides.
  • the same problem applies to joining together sections of titanium or titanium alloy pipe by welding in order to form lengths required in, for example, chemical processing plants .
  • a current alternative method for forming titanium and titanium alloy pipe without welding involves punching a core out of a solid bar of titanium or titanium alloy to leave a seamless pipe. Being a seamless pipe, there is no weld to compromise the band strength.

The equipment is costly and, therefore, contributes to the overall cost of the pipe. Accordingly, titanium or titanium alloy pipe produced by this method is
  • the cost is also affected by the waste produced in forming the pipe. Specifically, the core of titanium or titanium alloy must be melted down and reformed as a solid bar before being punched again to form another pipe . This process is on-going as cores are melted and bars are reformed. Processing of cores adds to the overall cost of the final formed pipe .
  • This alternative method involves spraying fine particles of titanium or titanium alloy onto a cylindrical
  • the particles are sprayed at supersonic velocities and bond together upon impact to build up a layer of titanium or titanium alloy. The extent of the build up determines the wall thickness of the pipe .
  • this alternative method does not produce titanium or titanium alloy pipe in lengths that are practical as a replacement for long sections of steel pipe. Short sections of titanium or titanium alloy pipe may be used to form an overall longer pipe. However, there is considerable cost involved in assembling a longer pipe because the short sections are difficult to weld together. While this alternative method can produce titanium or titanium alloy pipe more cost effectively than other methods, this cost benefit is off-set by the cost

  • the starter pipe 30 can be moved from a position with the mandrel 10 located within the starter pipe 30 ( Figure 1) and in a direction that is co-axial with a longitudinal axis of the mandrel 10. During operation, the starter pipe 30 is moved away from the mandrel 10 so the starter pipe 30 and the mandrel 10 are remote from each other.
  • Titanium alloy pipe 40 is formed by placing the mandrel 10 within the starter pipe 50 and rotating both in the same direction and at the same rate of rotation. Spraying of titanium alloy particles from a nozzle 20 is commenced when the nozzle 20 is positioned such that a deposition zone 14 for the titanium alloy particles coincides with a position wholly on and adjacent to the end of the starter pipe 30.

This movement causes a transition pipe 32 , in the form of a continuous layer of titanium alloy, to be created over the end of the starter pipe 30 and on the mandrel 10.
  • Such movement of the starter pipe 30 and mandrel 10, or the nozzle 20, continues until a small section of titanium pipe 40 is formed on the mandrel 10 and the deposition zone 14 is spaced a small distance from the transition pipe 32 , as in Figure 1.

  • the applicant believes that the primary cause of bonding between the mandrel 10 and the pipe 40 is thermal bonding caused by thermal expansion of the mandrel 10 relative to the formed pipe 40.
  • the applicant also believes that surface roughness of the mandrel 10, particle relaxation and chemical bonding of the titanium pipe 40 to the mandrel 10 contribute to bonding.
  • the applicant is not aware of the extent to which mechanical and chemical bonding and particle relaxation contribute to overall bonding of the titanium pipe 40 to the mandrel 10.
  • thermal bonding may be controlled by selecting a material for the mandrel 10 that has a co-efficient of thermal expansion that is less than the co-efficient of thermal expansion of titanium alloy. Expansion of the mandrel 10 is caused by spray 12 which is at an elevated temperature. Although not confirmed, it is thought that a steel mandrel is heated to a temperature of around 300 0 C. Steel has a coefficient of thermal expansion that is greater than the co-efficient of thermal expansion of titanium alloy and, therefore, a steel mandrel 10 will expand more than the titanium alloy pipe 40, thereby causing thermal bonding.
  • the mandrel 10 may be cooled so that it contracts away from the alloy pipe 40.
  • removal of the titanium alloy pipe 40 may be assisted or caused by heating the titanium pipe 40 in preference to the mandrel 10. The heating causes the titanium alloy pipe 40 to expand more than the mandrel 10, thereby releasing the titanium alloy pipe 40 from the mandrel 10.
  • Such removal of titanium alloy pipe 40 is suitable in the circumstances that the mandrel 10 has a coefficient of thermal expansion greater than that of the titanium alloy pipe 40.
  • the mandrel 10 may be formed of hard, wear resistant material to reduce surface erosion . Such material may be glass, ceramic or metal. It is also anticipated that chemical bonding plays a role in the overall process, but the material of the mandrel 10 may be selected to reduce or eliminate the effect of chemical bonding.
  • An alternative method of forming seamless titanium alloy pipe to ameliorate the effects of thermal bonding and particle relaxation involves adopting a mandrel 50 having a smaller circumference than the inner circumference of the tube 40 to be formed ( Figures 3 and 4) . This is shown in Figure 4 with the mandrel 50 having an outer radius R M less than the inner radius of the formed pipe Rp .
  • an axis of rotation of the mandrel 50 is off-set from an axis of rotation of the formed titanium alloy pipe 40 so that the outer surface of the mandrel 50 is in contact with or is closely spaced from an inside surface of the formed titanium alloy tube 40 in the deposition zone 14. In other regions, the mandrel 50 is spaced from the inside surface of the formed titanium alloy tube 40.
  • the smaller size of the mandrel 50 is selected to reduce, and preferably avoid, the bonding effects produced by thermal bonding and particle relaxation.
  • the size of the mandrel is selected to be smaller than the size of the formed pipe 40 after particle relaxation and after thermal contraction of the formed pipe 40.
  • the mandrel 50 and the formed pipe 40 are rotated at respective rates so the surface of the mandrel 50 passes through the deposition zone 14 at the point of contact between the formed pipe 40 and the mandrel 50 generally at a circumferential speed that is the same as the inner circumferential speed of the formed pipe 40.
  • the process may involve preferential heating of the bound particles in a heating zone 60 to assist with separation of the bound particles from the mandrel 50.
