HQ Pipeline Co., Ltd. supplies welded steel pipes with outer diameters from 219 mm up to 2 200 mm. The pipes are manufactured from carbon steel grades such as 10#, 20#, 45#, 16Mn and A106 (B and C), as well as standard structural steels St37 and St20#. Wall thicknesses are offered in schedules ranging from SCH5 through SCH40, SCH80, SCH160 to the extra-extra-strong (XXS) class, allowing pressure ratings from low-pressure water lines to high-pressure oil transport. All dimensions are cut to the tolerances prescribed in EN 10210, typically +/-0.5 % of the nominal size.
The standard surface finish is a black paint coat, with an optional oiled treatment for corrosion protection during storage and handling. In the steel pipe market, bundles are commonly wrapped in steel strips or packed on pallets, a practice that matches the packaging described by the supplier. Typical industry practice also includes a protective cap at each end to prevent damage during transit, especially for diameters above 1 000 mm.
These welded pipes are widely employed in oil and gas transmission pipelines, municipal water infrastructure, and structural frameworks for large-scale construction projects. Buyers often request FOB or CIF terms, and the supplier states a standard delivery window of 25 days after order confirmation, subject to client specifications. Payment is normally made by irrevocable Letter of Credit or Telegraphic Transfer, which aligns with common international trade practices for steel commodities. Prospective importers should verify the required wall-thickness schedule and surface treatment before finalising the contract.

Before placing an order, verify the exact outer‑diameter, wall‑thickness schedule and material grade required for your project. Request the mill test report and any certification that confirms compliance with EN 10210 or API 5L, especially if the pipe will be used in high‑pressure service. Confirm whether the black paint or oiling finish meets your corrosion‑protection specifications.
Discuss logistics early: agree on Incoterms such as FOB Qingdao or CIF Shanghai, and confirm the 25‑day delivery window. Payment terms are typically a Letter of Credit or Telegraphic Transfer; ensure these terms are documented in the purchase contract. Ask the supplier to provide a detailed packing list and container loading plan to avoid unexpected freight charges.
Arrange for third‑party inspection prior to shipment. Common checks include visual inspection of surface coating, dimensional verification, and non‑destructive testing for wall thickness. Request the mill test report, material certification and, if needed, a certificate of conformity to the relevant standards. These documents support smooth customs clearance and guarantee that the supplied pipes meet your technical requirements.
