Progress Made in Research on Cladding Process for Bimetal Clad Pipe

Comprehensively elaborated here in the paper are the cladding process types for bimetal clad pipes, i.e., the mechanical cladding process and the metallurgical cladding process. Focused on are the comparative analyses of separate technological advantages and disadvantages of these two major cladding processes. Based on the analysis result, it is proposed that based on the current production level, domestic bimetal clad pipe-making circles should borrow relevant research achievements and application experiences as made abroad to continue R & D of cladding process and welding process for bimetal clad pipes in a bid to lay a solid foundation for successful application of such pipes in harsh-conditioned oil and gas field.
