The product is a seamless pipe made from Super Duplex Stainless Steel UNS S31803 / 2205 / 1.4462, also known as SAF 2205. It offers exceptional corrosion resistance and high mechanical strength, suitable for demanding environments. The pipe conforms to ASTM A790 specifications and is supplied by Huzhou Gaolin Stainless Steel Tube Co., Ltd. in China. It is available in multiple grades including S31803 and SAF 2205 to match specific project requirements.
Manufacturing employs cold‑drawn or cold‑rolled processes followed by annealing, pickling and polishing to achieve a smooth surface. Typical industry dimensions for 2205 seamless pipe range from 0.5 in to 24 in nominal diameter with wall thicknesses from schedule 10 to 80. Standard pressure ratings for these sizes can reach up to 600 bar, depending on thickness and testing. The material’s typical tensile strength lies between 620 - 750 MPa, providing reliable performance in high‑stress service.
Primary applications include oil and gas transport, chemical processing lines, and seawater desalination plants. EPC contractors and plant integrators often specify this pipe to avoid chloride‑induced stress corrosion cracking. Huzhou Gaolin offers flexible minimum order quantities, FOB and CIF shipping options, and supplies ISO and SGS certified material test reports. Buyers should confirm lead time and payment terms directly with the supplier before placing an order.

Before placing an order, importers should request the mill test certificate, chemical analysis report and mechanical property test results to confirm the pipe meets the SAF 2205 grade and ASTM A790 requirements. Verifying the supplier’s ISO and SGS certifications adds confidence that the material has been inspected by recognised third‑party bodies. Any deviation from the stated specifications should be documented and approved prior to shipment.
Logistics for this product typically involve sea freight from the port of Shanghai or Ningbo, with the supplier offering FOB or CIF terms. Buyers need to agree on the incoterm, confirm the vessel schedule and arrange for a letter of credit or other payment method that aligns with their risk profile. Because the supplier’s response rate is not recorded, establishing a clear point of contact early helps avoid delays in finalising shipping documents.
Quality assurance should include a pre‑shipment inspection by an independent agency, focusing on dimensional compliance, surface finish and pressure testing. Importers may also request a third‑party non‑destructive examination to detect any internal defects. Upon arrival, customs clearance will require the material test certificates, invoice and packing list; ensuring these documents are complete will streamline the clearance process.
