Dual metal clad steel pipe is a steel pipe that combines the carbon steel base layer and the corrosion resistant layer through the composite method of internal cover (metallurgy binding) or lining (mechanical combination). The corrosion resistant layer can be austenitic stainless steel, copper base alloy, nickel base alloy, Hastelloy, titanium, titanium alloy, duplex stainless steel, etc. Clad steel pipe not only has the high corrosion resistance of the corrosion resistant alloy, but also has good bending strength and impact resistance of carbon steel. At the same time, rare metal resources such as Cr, Ni and Ti are saved on the premise of meeting the performance requirements.
