Import Flange — Buy in Bulk from Supplier in China

The forged flange from Shanghai Tongyang Pipe Fittings Co., Ltd. is manufactured for high-pressure industrial piping systems, with standard sizes ranging from 1 inch to 24 inches. The product is produced using forging processes that enhance grain structure integrity, improving mechanical strength and resistance to thermal cycling. Pressure ratings follow ASME B16.5 Class 150 to Class 2500, with material grades including ASTM A105 and A350 LF2 as specified in the listing.

Forged carbon steel is the primary material, offering good weldability and moderate corrosion resistance in non-severe environments. The flanges are typically supplied with raised face or flat face finishes, conforming to ASME B16.5 dimensional standards. While the listing does not confirm certification status, the manufacturing method aligns with common industry practices for pressure-containing components in oil and gas and chemical processing. Surface treatment and machining tolerances are consistent with standard forged fittings.

These flanges are commonly used in petrochemical plants, refineries, and water treatment facilities where pipeline integrity under pressure is critical. Buyers include engineering contractors, maintenance departments in heavy industry, and OEMs sourcing components for modular systems. Packaging is typically in wooden crates to prevent surface damage during transport. Trade terms such as FOB Shanghai or CIF are standard, though exact MOQ and lead time require direct confirmation with the supplier.

Shanghai Tongyang Pipe Fittings Co., Ltd. operates from the Xinzhuang Industry Zone in Shanghai, with a registered address and industrial facility in the region. The supplier is classified as imported and harbor-trusted, indicating verified export activity and logistics reliability.
