Super Duplex Stainless Steel Pipe
The Super Duplex Stainless Steel Pipe offered by Kcm Special Steel Co., Ltd. is manufactured from UNS S32750 / S32760 alloy containing 25 % chromium, 7 % nickel and 3.5 % molybdenum. The pipes comply with ASTM A790/A789 standards and are supplied in both seamless and welded forms. Diameter ranges from 6 mm up to 3000 mm outer diameter, with wall thicknesses between 0.8 mm and 60 mm. The product catalogue also lists square and rectangular sections for specialised applications.
Super Duplex grades deliver superior resistance to chloride‑induced stress corrosion cracking, making them a preferred choice over standard austenitic grades in oil‑field and offshore environments. Typical tensile strength for this alloy exceeds 620 MPa and it can operate continuously between - 50 °C and +300 °C. The material is often heat‑treated to a solution‑annealed condition to optimise corrosion performance. Kcm maintains a ready stock of these pipes to support urgent project timelines.
Primary buyers include petrochemical plant engineers, offshore platform contractors and high‑pressure pipeline developers who require reliable performance under extreme conditions. The supplier can provide bulk quantities on FOB or CIF terms, with packaging in wooden crates and protective film as standard. Buyers should request mill test certificates and dimensional inspection reports before confirming the order. Lead times and payment schedules are negotiated directly with Kcm.

Super Duplex Stainless Steel Pipe is engineered for the most demanding environments in oil and gas extraction, petrochemical processing, and offshore platforms. Manufactured to ASTM A790/A789 standards, these pipes offer superior chloride stress corrosion cracking resistance compared to standard austenitic grades. Ideal for high-pressure and high-temperature applications where conventional stainless steels fail, they are available in seamless and welded configurations in sizes ranging from 6mm to 3000mm OD with various wall thickness schedules.

Sourcing Super Duplex Stainless Steel Pipe from Kcm Special Steel Co., Ltd. - China Import Guide
Before placing an order, importers should obtain the mill test certificate and a recent chemical analysis report to confirm the alloy composition and mechanical properties. Dimensional inspection reports should also be requested to verify outer diameter and wall‑thickness tolerances. Verifying these documents helps ensure that the pipe will meet project specifications and regulatory requirements.
Logistics for the pipe are typically arranged under FOB or CIF terms, with shipment in wooden crates secured on standard 20‑ or 40‑foot containers. Lead times are not published, so buyers need to discuss production scheduling and container loading dates directly with Kcm. Common payment arrangements include a 30 % advance letter of credit followed by balance against documentary proof of shipment, but terms can be negotiated.
Quality assurance is usually performed by third‑party inspection agencies that conduct hydrostatic pressure testing and visual weld inspection before dispatch. Importers may also request post‑manufacture non‑destructive testing to verify compliance with ASTM A790. Retaining copies of the inspection certificate, test results and packaging list will simplify customs clearance and downstream acceptance.
