high quality socket welding flange

Socket welding flange refers to the flange in which the end of the pipe is inserted into the flange ring step and welded on the pipe end and the outside. There are two types with and without neck. The neck tube flange has good rigidity, small welding deformation and good sealing performance, and can be used in occasions where the pressure is 1.0~10.0MPa. Type B flanges for containers are also socket welding flanges, which are used in occasions with high sealing requirements. When designing, socket welding flanges can be checked as integral flanges.       Material     Carbon steel ASTM A105, A350 LF1, LF2, LF3, LF6, CL1/CL2,; A694 F52, F60, F65, F70; A516 Gr. 60, 70; BS-EN 10222-2 P245GH, P280GH; EN10222-4 P355NH, P355QH; EN10273 P250GH, P265GH; DIN 17243 C22.8; VD-TUEV350/3 C21; GB/T…
