A process for producing clad pipe comprises forming a hollow body (S10) of base material, bonding a cladding material metallurgically to the base material. (S12) to form a composite body and subsequently extruding the composite body to form a pipe. This process allows the metallurgical bond to be validated using non-destructive methods prior to extrusion. Any areas tha t arc unbonded will be detected, thereby reducing wastage. Moreover, because the metallurgical bond is achieved prior to extrusion, the cladding thicknes s is controlled during the extrusion process, avoiding migration of the clad material into the base material by disproportionate amounts. |
