ABSTRACT:
This invention relates to a method of manufacturing bi-metallic tubing by the successive steps of explosive bonding, hot extrusion and co-extrusion. Bi-metallic tubing, having an inner wall made from a corrosion resistant material, is of particular use in the oil and gas industries. The invention offers a number of advantages over previously known manufacturing methods, such as increased cladding capacity, reduction in the number of joints required, and an improvement in dimensional accuracy. These are achieved by explosively bonding a tube 3 of a first metal to a substantially incompressible billet 1 of a second metal. A length of the bonded composite 15 so formed is subsequently hot extruded to form a bi-metal shell 25. A length of the shell 25 is then placed within the bore of a hollow billet 33, the interface 35 formed between the shell 25 and billet 25 sealed, and the assembled composite 39 so formed co-extruded to form a bi-metal tube 41.
