Duplex steel stainless steel
Tobo International Trading supplies duplex stainless steel butt weld pipe fittings in UNS S32205 and UNS S32750 grades, conforming to ASME B16.9 and B16.28 standards. These fittings are available in sizes ranging from 1/2 inch to 48 inches, with wall thicknesses spanning Schedule 10S to XXS, tailored for high-pressure and corrosive environments. The material composition includes approximately 22% chromium, 5% nickel, and 3% molybdenum, delivering enhanced resistance to pitting and stress corrosion cracking compared to standard austenitic grades.
The fittings are manufactured to meet exacting dimensional tolerances and surface finish requirements typical in oil and gas, chemical processing, and desalination industries. Surface conditions are generally pickled and passivated unless otherwise specified, and all products are traceable to mill test reports. These fittings are not plated or coated; their corrosion resistance derives from the inherent metallurgical structure of duplex stainless steel, which combines ferritic and austenitic phases for superior mechanical strength and durability.
Buyers in industrial sectors requiring long-term integrity under chloride exposure commonly source these fittings for pipelines, heat exchangers, and pressure vessels. Trade terms are flexible, with standard packaging in wooden crates or palletized bundles secured with anti-corrosion paper. Export documentation includes commercial invoices, packing lists, and mill test certificates. Buyers should confirm exact dimensions, pressure ratings, and end preparation before placing orders, as custom modifications are possible but require direct supplier validation.

Sourcing Duplex steel stainless steel from Tobo International Trading (Shanghai) Co., Ltd. - China Import Guide
Before ordering, verify the material grade with a certified mill test report showing actual chemical composition and mechanical properties. Confirm that the fittings meet ASME B16.9 and B16.28 dimensions, and request a surface finish specification. Do not rely on product descriptions alone - insist on documentation tied to the actual production batch. Ensure the supplier can provide traceability from raw material to final product.
Logistics terms are not specified in the listing. Buyers must confirm Incoterms (such as FOB Shanghai or CIF destination), lead time for production and shipment, and packaging method. Standard lead times for custom fittings range from 4 to 8 weeks. Payment terms like T/T or L/C should be negotiated directly, and buyers should require a proforma invoice with exact product codes and quantities before payment.
Upon delivery, inspect the fittings for surface defects, dimensional accuracy, and correct labeling. Verify that the heat number on the product matches the mill test certificate. Conduct a visual inspection for signs of contamination or improper storage. If critical for safety, arrange for third-party inspection before customs clearance. Retain all documentation for warranty and compliance purposes.
