China Duplex Steel BLRF Flanges Manufacturers, Suppliers, Factory

Zhejiang Chengyuan is an experienced manufacturer and supplier of 304 stainless steel socket weld flanges in China. These flanges are used when the end of a pipe needs to be inserted into a flange ring step and welded on the outside. Our socket welding flanges come in two types - with neck and without neck. The flange with neck tube has excellent rigidity, small welding deformation, and good sealing performance, making it ideal for use in high-pressure environments (1.0 to 10.0 MPa). Type B flanges are also available for vessels, which have even higher sealing requirements. We offer socket welding flanges made of different materials including carbon steel, stainless steel, and alloy steel. Carbon steel options include ASTM A105, 20#, Q235, 16Mn, ASTM A350 LF1, LF2 CL1/CL2, LF3 CL1/CL2, and ASTM A694 F42, F46, F48, F50, F52, F56, F60, F65, and F70. Stainless steel options include ASTM A182 F304, 304L, F316, 316L, 1Cr18Ni9Ti, 0Cr18Ni9Ti, 321, and 18-8.
