Import Cold Drawn Seamless Steel Pipes, Made Of St45 — Buy in Bulk from Supplier in China

Zhejiang Dingxin Steel Tube Manufacturing Co., Ltd. supplies cold drawn seamless steel pipes made from ST45 carbon steel. The pipes are produced with outer diameters ranging from Ø10 mm to Ø37 mm and are available in a variety of lengths to suit project requirements. Cold drawing improves dimensional accuracy and surface finish, while the seamless construction removes weld lines that could become pressure points. The material grade ST45 provides a good balance of strength and ductility for demanding environments.

Within the carbon‑steel pipe market, wall thicknesses commonly fall between 2 mm and 6 mm for the listed diameters, and tensile strength values are typically 560 MPa or higher. Dimensional tolerances are usually ±0.2 mm for diameter and ±0.5 mm for length, meeting standards such as ISO 11960 and EN 10210. Surface roughness after cold drawing is generally limited to Ra 1.6 µm, which facilitates downstream welding or coating processes. These typical parameters ensure compatibility with pressure‑bearing applications across sectors.

The pipes are widely used in automotive chassis components, oil‑field pipelines, and structural steelwork where reliability under load is essential. Importers typically select Zhejiang Dingxin for projects that require consistent mechanical properties and the ability to order in batches ranging from a single spool to full container loads. The supplier states that FOB and CIF shipping options are available, with payment accepted via L/C or T/T, and packaging is customised to protect the tubes during transit.

Zhejiang Dingxin Steel Tube Manufacturing Co., Ltd. is located in Liuli Industrial Zone, Haiyan County, Jiaxing, Zhejiang, China (postal code 314301). The company is listed as an imported‑tier supplier with a harbor trust tier, indicating it has been verified through trade data and customs records.

The platform data shows a response rate of 0 % and no recorded average response time, which suggests the supplier does not currently respond to inquiries through the listing. The profile confirms that the company offers cold drawn seamless steel pipes but does not disclose specific minimum order quantities, certifications, or production capacity.
