S31803 S32205 Duplex Steel Pipe
The S31803 S32205 Duplex Steel Pipe supplied by Wenzhou Chenhui Steel Co., Ltd is manufactured from duplex stainless steel UNS S31803 / S32205 (2205 grade). It complies with ASTM A790/A928, GB/T 14976‑2012, EN 10216‑5 and other international standards. Available diameters range from 6 mm up to 762 mm (30 in) and wall thicknesses from 0.9 mm to 50 mm, offered in schedules such as SCH 5, SCH 10, SCH 40S and SCH 80S. Both seamless and welded configurations can be supplied with plain or beveled ends.
Duplex alloys provide a dual‑phase austenitic‑ferritic structure that delivers higher yield strength and superior resistance to chloride‑induced stress corrosion compared with standard austenitic grades. Typical surface finishes include 180G, 320G, 400G satin and 600G mirror, while tolerances follow the relevant standards (e.g., ±0.2 mm for OD). The pipes are delivered in 6 m lengths as standard, with custom lengths and random‑length options on request. Packaging is normally in wooden crates with plastic strapping, but alternative packing can be arranged per buyer specifications.
These pipes are widely specified for offshore oil and gas, chemical processing, seawater desalination, power generation and shipbuilding projects. Engineering contractors and bulk buyers usually request ISO 9001‑2008 certification and third‑party inspection reports such as EN 10204 3.1. Trade terms mention T/T or L/C payment, with a typical delivery window of 30‑45 days depending on order volume. Buyers should confirm exact incoterms, lead time and any special finishing requirements directly with the supplier.

Sourcing S31803 S32205 Duplex Steel Pipe from Wenzhou Chenhui Steel Co., Ltd - China Import Guide
Before placing an order, buyers should verify the supplier’s ISO 9001‑2008 certification, request the latest EN 10204 3.1 inspection certificate and confirm that the pipe dimensions and finish meet the project specification. Asking for a recent chemical composition analysis report is advisable, especially for applications with strict corrosion‑control criteria.
Logistics typically follow FOB or CIF incoterms, but the exact term must be agreed with the supplier. The listed delivery window is 30‑45 days, although actual lead time depends on order size and any custom length or finish requirements. Payment is usually arranged via T/T or L/C, and buyers should confirm the acceptable currency and document requirements during the quotation stage.
Quality assurance relies on third‑party testing; the supplier mentions UT, RT and other NDT methods as well as visual inspection reports. Importers are encouraged to arrange an independent pre‑shipment inspection if the contract value warrants it, and to retain all test reports for customs clearance and future warranty claims.
