The 2507 flange from Tobo International Trading Co., Ltd. is a duplex stainless steel component designed for high-pressure piping systems in industrial environments. The 2507 grade, also known as UNS S32750, offers a typical yield strength of 550 MPa and a tensile strength of 800 MPa, making it suitable for demanding applications. The flange is manufactured to withstand corrosive and chloride-rich conditions common in oil and gas, chemical processing and marine industries.
Duplex 2507 combines austenitic and ferritic microstructures, providing typical pitting resistance equivalent number (PREN) values above 40, which exceeds that of standard 316 stainless steel. The flange is typically produced in sizes ranging from DN15 to DN600 and pressure classes from PN16 to PN100, adhering to standards like ASME B16.5 or EN 1092-1. Surface finish is usually pickled and passivated to enhance corrosion resistance.
These flanges are used to connect pipes, valves and pumps in systems transporting fluids or gases under high pressure and temperature. Buyers in industries such as offshore platforms, desalination plants and chemical processing rely on 2507 for its balance of strength and corrosion resistance. Tobo International Trading Co., Ltd. offers the flanges in various dimensions and pressure ratings, but confirm exact sizes, standards and certifications directly with the supplier.

Before ordering, confirm the exact grade, size and pressure class of the 2507 flange with Tobo International Trading Co., Ltd., as these must match your piping system’s specifications. Request material test reports (MTRs) to verify the chemical composition and mechanical properties, particularly the PREN value, which is critical for corrosion resistance in chloride-rich environments. Ensure the flanges comply with the required standards, such as ASME B16.5 or EN 1092-1.
Clarify the incoterms, as these define cost and risk responsibilities during transit from China. Tobo International Trading Co., Ltd. is based in Shanghai, so sea freight from the Port of Shanghai is typical. Confirm lead times, as trading companies may require additional time to source the flanges from manufacturers. Payment terms should be negotiated in advance, with options like letters of credit or telegraphic transfers commonly used for international transactions.
Inspect the flanges upon receipt for dimensional accuracy, surface finish and marking compliance. Check for defects such as cracks, pits or improper machining, which can compromise performance. Request a pre-shipment inspection by a third party if the order is large or critical. Ensure the supplier provides a packing list, commercial invoice, certificate of origin and any applicable compliance certificates for customs and regulatory requirements.
