Abstract: The outer layer of clad pipe is carbon steel such as grade B(L245),X42(L290),X52(L360),X60 (L415),X70(L485),and the inner layer is 18-8 type austenite stainless steel or ferrite-austenite dual phase stainless steel. The cladding process, anti-corosion technology of pipe outer surface, welding process of pipe and properties and ap- plication of bimetallic clad pipe are presented in this paper.
