Bimetal composite pipes composed of carbon steel and corrosion resistant alloys have attracted increasing attention for the applications in the fields of transferring pipes, downhole tubes, reservoirs and heat exchangers. It shows superior properties such as corrosion resistance of the corrosion resistant alloys and formability, and mechanical properties of carbon steels, which satisfy the requirements of both anti-corrosion and mechanical properties applied in oil and gas filed with an affordable price.
A series of manufacturing methods for the fabrication of bimetal composite pipes, including mechanical bonding method, welded pipe using the clad plate and inner surfacing welding clad pipe, have been applied in recent years.
