| High Light | ASTM A928 Duplex Stainless Steel Pipe ，S31200 Duplex Stainless Steel Pipe ，Electric Fusion Welded duplex pipe | ||
ASTM A928 is a specification for electric fusion welded duplex stainless steel pipe with the addition of filler metal. This specification covers various grades of duplex stainless steel, including S31200, S31260, S31500, S31803, and S32003. These pipes are widely used in various industries due to their excellent corrosion resistance, high strength, and good weldability.
The ASTM A928 specification covers electric fusion welded duplex stainless steel pipes with a nominal pipe size ranging from 14 inches to 96 inches. The pipes are manufactured using the electric fusion welding process, which involves the joining of two metal plates through the application of heat generated by an electric arc. The filler metal is added during the welding process to ensure a strong and durable bond.
