Wenzhou Guopeng Stainless Steel Co., Ltd supplies seamless stainless‑steel pipes manufactured from 300‑series and duplex grades. The product range covers grades 304, 304L, 316, 316L, 2205 and 2507, with nominal diameters from 6 mm up to 630 mm and wall thicknesses between 0.5 mm and 40 mm. Pipes are delivered in standard lengths of 2 m to 12 m, and can be ordered to customer‑specified lengths. All items are produced to meet ASTM A312 and ASME SB677 requirements.
The cold‑rolled and cold‑drawn finishes provide a smooth interior surface suitable for high‑pressure service. 300‑series grades offer typical corrosion resistance to chloride environments, while duplex grades deliver higher strength and superior stress‑corrosion performance. In the stainless‑steel market, these dimensions and tolerances align with standard pipe specifications used in process plant construction. Typical dimensional tolerance for diameter is ±0.2 mm, and pressure ratings commonly reach up to 600 bar for the listed grades.
Common applications include oil and gas pipelines, petrochemical processing, food‑grade handling and chemical transport where leak‑free performance is essential. Buyers such as plant engineers, procurement agents and EPC contractors usually request mill‑test reports and certification of compliance. The supplier indicates flexible order quantities and can arrange shipment in bundled pallets, but exact MOQ, lead time and incoterm details should be confirmed directly. Payment terms and shipping arrangements are negotiated per transaction.

Before placing an order, confirm the exact grade, diameter, wall thickness and length required for your project, and request the latest mill‑test report to verify compliance with ASTM A312 and ASME SB677. Ask the supplier to provide a material traceability certificate and, if needed, a third‑party inspection certificate. Verifying these documents helps ensure the pipe will meet the pressure and corrosion requirements of your application.
Discuss shipping arrangements early, specifying the preferred incoterm such as FOB Wenzhou port or CIF Shanghai, and confirm the expected lead time based on the chosen dimensions and finish. Enquire about palletisation details, container loading plans and any special handling for long lengths. Clarify payment conditions, typically a deposit against the pro‑forma invoice followed by balance on document receipt, and ensure that any bank guarantees or letters of credit meet your company policy.
Arrange for pre‑shipment inspection by an independent agency to verify dimensions, wall thickness and surface finish against the agreed tolerances. Request a final quality report that includes visual inspection results, non‑destructive testing outcomes and the full set of certification documents. Maintaining a record of these checks will simplify customs clearance and provide assurance that the delivered pipes conform to the specified standards.
