Import Flange And Forged Steel Part — Buy in Bulk from Supplier in China

Boyue Pipe And Fitting Co., Ltd. supplies forged steel flanges and components manufactured from ASTM A105, ST-37, and stainless steel grades including 304 and 304L. These parts are produced using forging processes to enhance grain structure integrity, making them suitable for high-pressure and high-temperature environments. The product range covers sizes from 1/2 inch to 72 inches, with pressure classes from 150# to 2500#.

Material selection is determined by application: ASTM A105 is used for carbon steel flanges in oil and gas lines, while 304 and 304L stainless steel are specified for corrosive media or chemical processing. The forging process ensures uniform microstructure and eliminates casting defects. Surface finish complies with ASME B16.5 for raised face and flat face types. Packaging is in plywood cases with internal moisture barriers.

These components are used in oil refineries, petrochemical plants, power generation, and industrial piping systems where structural integrity under stress is critical. Buyers include engineering contractors, OEMs, and maintenance suppliers in the Middle East, North America, and Southeast Asia. Trade terms are typically FOB Dalian or CIF, with MOQs based on size and grade. Lead times vary from 4 to 10 weeks depending on complexity and material availability.
