ASME B16.5 A105 DN50 Class 2500 Socket Weld Flange Carbon

This socket weld flange is strictly produced by Dingxiang Jinyu Factory in accordance with ASME B16.5 American standard for flanges. It is forged from premium ASTM A105 carbon steel, nominal diameter DN50, pressure class Class 2500, suitable for high-pressure pipelines in oil & gas, chemical and power industries. ASTM A105 carbon steel features outstanding mechanical performance, high temperature and impact resistance. Forging eliminates internal porosity to guarantee stable structural strength. Socket weld design simplifies pipe installation with uniform weld stress; precisely machined sealing surface achieves zero leakage with high-pressure gaskets. Our factory supplies full-range forged flanges: besides DN50, larger sizes from DN65 up to DN1400 are available for all pressure classes Class150–Class2500. All items pass full NDT and hydrostatic tests with standard-compliant tolerances. Resistant to medium corrosion and long service life, customizable mass production is supported. Widely exported to high-pressure engineering projects across Europe and America, it is a core forged fitting for high-pressure pipeline connections
