The product is a carbon seamless steel pipe supplied by Hunan Great Steel Pipe Co., Ltd. It is manufactured from carbon steel grades such as Grade 20, ASTM A106 Grade B and API 5L Grade B. The pipe dimensions cover outer diameters from 13.72 mm to 914.4 mm, wall thicknesses between 1.65 mm and 22 mm, and lengths ranging from 0.5 m to 20 m. The material conforms to standards including API 5L, ASTM A106/A53, DIN 2391, ASTM A179/A192, EN 10210 and EN 10208.
Production employs hot‑rolling or cold‑drawing followed by heat‑treatment options such as annealing, normalising, stress‑relief, cold finishing or quenching‑and‑tempering to achieve uniform wall thickness and pressure resistance. Each batch undergoes hydraulic testing, X‑ray, eddy‑current inspection, chemical composition analysis and mechanical property testing, with third‑party verification available from bodies such as BV, SGS or Lloyd's. Typical industry practice for pipes of this size includes a pressure class of PN 10‑PN 40 and schedule ranges from SCH 20 to SCH XXS.
These pipes are widely used in oil and gas transmission, boiler systems and general mechanical engineering projects. Importers such as refinery operators, power‑plant contractors and infrastructure developers source them for their reliability under high‑pressure service. Pricing is normally quoted per metric ton on a CFR or FOB basis and delivery can be arranged from major steel‑producing ports in China; exact MOQ, lead time and payment terms should be confirmed directly with the supplier.

Before placing an order, verify the exact grade, outer diameter, wall thickness and standard required for your project. Request the relevant ISO or MTC certificates and confirm whether the pipe has undergone the heat‑treatment you need. Ask the supplier to provide the latest hydraulic test and X‑ray inspection reports to ensure compliance.
Importers should clarify the preferred Incoterm - typically CFR or FOB from a Chinese steel‑producing port - and confirm the delivery condition code (e.g., BKS, NBK). Lead times are not published, so ask for an estimated schedule based on the required size and quantity. Payment terms are usually negotiated as T/T or L/C; obtain written confirmation before finalising the contract.
Quality assurance is critical for high‑pressure applications. Arrange a third‑party pre‑shipment inspection if possible, and request the full inspection report, including chemical analysis and mechanical property results. Ensure that the supplier provides a certificate of conformity to the declared standard and retains traceability for each batch.
