The Super Quality ERW Welded Tube for Oil and Gas is produced by Hunan Great Steel Pipe Co., Ltd in Changsha, Hunan, China. It is fabricated from carbon‑steel conforming to API 5L grades ranging from X42 to X70 and complies with standards such as GB/T 9711‑1, ISO 3138‑1 and EN 10219. The tube is offered with outer diameters from 10 mm up to 1 016 mm and wall thicknesses between 1.7 mm and 52 mm, in both fixed and random lengths. End preparations include square, plain, beveled or threaded finishes as specified by the buyer.
The electric‑resistance welding (ERW) process provides a cost‑effective alternative to seamless pipe while delivering acceptable tensile strength for mid‑to‑high pressure pipelines. Typical tensile strength for API X70 grade steel is around 500 MPa, and the material’s chemical composition meets the carbon‑steel limits defined in API 5L. Standard pipe tolerances for diameter and wall thickness follow API 5L PSL1/PSL2 specifications, with permissible deviations of ±0.5 % for OD and ±12 % for wall thickness. Surface treatments such as bare, lightly oiled, painted or zinc coating are available to match corrosion‑resistance requirements.
Buyers in the petroleum, chemical and power sectors use these tubes for line‑pipe, structural and boiler applications, often ordering in bulk tons rather than by individual pieces. The supplier lists a minimum order of one ton and indicates a delivery window of 7‑30 days after deposit, though exact Incoterms and payment conditions must be confirmed. Prospective purchasers should request certification documents (e.g., API product data sheet and ISO‑9001) and arrange for dimensional and non‑destructive testing before acceptance.

Hunan Great Steel Pipe Co., Ltd. is situated on the 22nd floor of the Royal Wing Tower, Long Champ International Building, Xiangfu Road, Changsha, Hunan, China. The company carries a harbor trust tier and currently shows a 0 percent response rate with no average response time recorded, indicating limited communication data. It operates as a manufacturer and exporter of steel pipe products.
The listing specifies that the firm produces ERW welded tubes to API 5L specifications and offers a range of surface treatments and packaging options, but it does not disclose production capacity, specific quality‑management certifications beyond those offered on request, or client references. Prospective buyers should therefore request a copy of the ISO‑9001 certificate and sample pipe for dimensional testing before committing to large orders.
Super quality ERW welded tubes are widely used in oil and gas transmission pipelines, meeting API 5L standards with grades including X42 through X70. These carbon steel welded pipes are manufactured via electric resistance welding and are suitable for high-pressure applications in the petroleum and natural gas industries. ERW tubes offer a cost-effective alternative to seamless pipes for mid-to-high pressure oil and gas pipeline systems, with sizes ranging from 10mm to 1016mm outer diameter.

Before ordering, importers should obtain a product data sheet that lists the exact API grade, outer‑diameter and wall‑thickness tolerances, as well as the material’s chemical composition. Request the latest API 5L product data sheet and any third‑party test reports (e.g., tensile strength, hydrostatic test) to confirm compliance with pipeline standards. Verifying the selected end preparation and surface‑treatment specifications will also prevent mismatches in downstream installation.
The supplier indicates a minimum order of one ton and a delivery window of 7‑30 days after deposit, but does not state the Incoterm to be used. Buyers should agree on a clear term such as FOB Changsha or CIF Shanghai and confirm the accepted payment method, noting that T/T and L/C are mentioned. Clarifying the exact packaging (bundle or bulk with end protection) will aid in freight planning and cost estimation.
Arrange for a pre‑shipment inspection that includes dimensional checks, wall‑thickness measurement and non‑destructive testing in line with API 5L requirements. Insist on receiving a certificate of conformity, the relevant API product data sheet and a material safety data sheet for any coating applied. Maintaining a record of the inspection report and packing list will streamline customs clearance and quality assurance on arrival.
