Import Flange — Buy in Bulk from Supplier in China

These flanges are manufactured in compliance with ANSI B16.5 and B16.47 standards, available in slip-on (SO), weld neck, and other types, with pressure ratings from 150 to 2500 psi. Materials include ASTM A105 carbon steel, ASTM A350 LF2 for low-temperature service, and austenitic grades such as A182 F304L and F316L. The product range spans from 3/8 inch to 72 inch nominal pipe size, suitable for refinery, petrochemical, and power generation applications.

The flanges are produced using forged or cast methods depending on material and size. ASTM A105 is the standard for carbon steel flanges up to 24 inches, while larger sizes may use A694 F52 to F65 forgings. Austenitic stainless flanges meet A182 specifications with controlled carbon content for weldability. Facing types include raised face (RF), flat face (FF), and ring type joint (RTJ), each suited to different sealing requirements and gasket materials.

Buyers in heavy industry use these flanges for high-pressure piping systems requiring precise dimensional control and material traceability. They are packed in plywood cases weighing 500 to 700 kilograms each, with custom packaging available. The supplier references DIN and EN 1092-1 standards, indicating compatibility with European systems. Lead time and minimum order quantity are not listed and must be confirmed directly. Export documentation includes material certificates and packing lists.
