The pipes are manufactured without welds, giving a continuous grain structure that tolerates high internal pressure. Outer diameters are offered from 21.3 mm up to 508 mm, matching the dimensions required by oil‑gas transmission and structural projects. The product conforms to API 5L, ASTM A106 and GB/T 8163 specifications, which are referenced in the supplier’s technical data. These dimensions and grades are listed in the catalogue for bulk export. The seamless process is performed on cold‑drawn billets to achieve the stated tolerances.
The carbon steel grades listed are standard in the global pipe market, where 20# is used for low‑pressure services and 45# for medium‑pressure pipelines. 16Mn offers improved low‑temperature toughness, a characteristic valued in boiler and mechanical structures. Typical tensile strength for these grades ranges between 400 MPa and 550 MPa, and yield strength lies between 250 MPa and 350 MPa. In the industry, seamless pipes of this size class are normally supplied in 20‑foot containers or as bulk cargoes. The supplier notes that the pipes are ready for immediate loading upon order confirmation.
Major purchasers include oil‑field contractors, power‑plant engineers and steel‑fabrication firms that require reliable pressure‑resistant tubing. Orders are usually shipped in standard 20‑foot containers or in bulk rolls, with pricing expressed per metric ton. The listing does not disclose a minimum order quantity, lead time or Incoterms, so buyers should request those details directly from the supplier. Payment terms are not specified in the public data. Prospective importers are advised to verify the applicable standard certificates before finalising the contract.

Before placing an order, importers should verify that the pipe dimensions, grade certifications and compliance with API 5L, ASTM A106 or GB/T 8163 are documented. Request the mill test report and any third‑party inspection certificates to ensure the product meets the required specifications.
Logistics for bulk steel pipe are usually arranged on a 20‑foot container basis or as bulk cargo. Incoterms, lead‑time estimates and payment conditions are not disclosed publicly, so these details must be confirmed with the supplier during negotiation. Common payment methods include T/T against documents or LC, but the exact terms should be agreed in the contract.
Quality assurance commonly involves pre‑shipment inspection, dimensional verification and surface‑finish assessment. Importers are advised to engage a qualified inspection agency to perform a hydrostatic test and verify the mill test report before loading. Ensure that the shipping documents include a certificate of conformity and a packing list that records the outer‑diameter and wall‑thickness of each bundle.
