Import Flange — Buy in Bulk from Supplier in China

The carbon steel flange supplied by Wuxi Sunrising Steel Co., Ltd conforms to ASTM A694 / A694M standards, with available grades F42, F52, F60, F65, and F70. These flanges are machined to precise dimensional tolerances for leak-proof sealing in high-pressure systems, with standard face types including raised face and flat face as per ASME B16.5. The material composition aligns with carbon steel specifications for pressure service, offering structural integrity under thermal and mechanical stress.

These flanges are forged from low-alloy carbon steel with controlled manganese and carbon content to ensure consistent hardness and weldability. Typical industry practice for this grade includes a maximum sulfur content of 0.035% and phosphorus below 0.035%, which enhances ductility and reduces brittleness. Surface finish follows standard mill conditions unless otherwise specified, and no coating or plating is applied unless requested by the buyer.

Common applications include oil and gas pipelines, chemical processing units, and power generation facilities where connection integrity is critical. Buyers include engineering contractors, OEM manufacturers, and maintenance suppliers servicing industrial plants. Trade terms are available as FOB or CIF from Shanghai or Ningbo ports, with packaging in wooden crates or steel strapping. Minimum order quantities are not stated and must be confirmed directly with the supplier.
