A182 f51 flange
The A182 F51 flange is a stainless steel piping component engineered for high-pressure and high-temperature applications. Constructed from ASTM A182 F51 duplex stainless steel, it offers superior strength and corrosion resistance compared to standard austenitic grades. This flange is available in welding-neck, slip-on and blind configurations to suit varying installation needs in industrial systems.
Duplex stainless steel combines austenitic and ferritic microstructures, delivering typical yield strength of 550 MPa and elongation of 25 percent, with pitting resistance equivalent numbers (PREN) often exceeding 35. Common industry finishes include pickled or bright annealed surfaces, while typical dimensional tolerances follow ASME B16.5 for flanges up to NPS 24. The material maintains integrity in chloride-rich environments, making it a standard choice for offshore and chemical processing plants.
These flanges are primarily sourced by EPC contractors and plant operators in oil and gas, petrochemical and desalination sectors. Typical bulk orders specify ASME B16.5 Class 150 to 2500 pressure ratings, with buyers confirming exact diameter, schedule and facing type (RF, RTJ) to match pipeline specs. Packaging usually involves wooden crates or pallets with waterproof wrapping to prevent transit damage, and Incoterms such as FOB Shanghai are commonly negotiated.

Sourcing A182 F51 Flange from Tobo International Trading Co., Ltd. - China Import Guide
Before ordering A182 F51 flanges from Tobo International Trading Co., Ltd., verify the material’s chemical and mechanical properties against your project specifications. Request mill certificates and third-party inspection reports to confirm compliance with ASTM A182 and ASME B16.5 standards. Check that the flange type, pressure class, and dimensions match your piping system’s requirements to avoid costly mismatches.
Confirm logistics details such as lead time, which can vary from 4 to 8 weeks for non-stock items, and packaging standards to prevent transit damage. Discuss Incoterms like FOB Shanghai to clarify responsibility for freight and insurance. Payment terms such as T/T or L/C should be agreed upon in advance, with milestones tied to inspection and shipment to mitigate risk.
Quality checks should include visual inspection for surface defects, dimensional verification using calipers or templates, and hardness testing to ensure the material meets F51 specifications. For critical applications, arrange for independent third-party inspection at the supplier’s facility or port of loading. Ensure all documentation, including MTCs and NDE reports, is available for customs clearance and final acceptance.
