ANSI B16.5 400 LBS Pipe Flange

Typically, ANSI B16.5 Class 400 Flanges are forged from materials like carbon steel, stainless steel, alloy steel, or duplex steel, depending on the specific service requirements. These flanges can handle pressures of around 990 psi at 100°F (for carbon steel), making them a robust choice for demanding systems. You can find various types, including weld neck, slip-on, blind, threaded, socket weld, and lap joint flanges. They boast impressive mechanical properties, such as high tensile strength, excellent resistance to pressure and temperature changes, and good corrosion resistance. Plus, they come with raised face (RF) or ring-type joint (RTJ) sealing surfaces to enhance sealing efficiency.
