从China供应商批量进口A106b, 53b

Wuxi Dexin Steel Tube Co., Ltd supplies A106B and A53B seamless carbon steel pipes from their base in Wuxi, Jiangsu Province. The source data indicates an outer diameter span of 20 mm to 1200 mm with wall thickness up to ​​150 mm, though this thickness figure appears to reference maximum capability rather than standard stock dimensions. The pipes are manufactured to ASTM A106 and ASTM A53 specifications, with additional compliance claimed against GB, DIN and JIS standards.

The A106B grade is a carbon-manganese steel designed for elevated-temperature service, typically holding a minimum tensile strength of 415 MPa and yield strength of 240 MPa at room temperature. A53B is the lower-strength counterpart more commonly used for mechanical and pressure applications where thermal stress is less severe. Both grades are produced as seamless pipes, eliminating weld-seam weak points and improving fatigue resistance under cyclic pressure loading. The material chemistry typically contains 0.30% carbon maximum, 0.29-1.06% manganese, and controlled residuals of phosphorus and sulphur to ensure weldability and notch toughness.

These seamless pipes serve oil and gas transmission lines, power plant boiler tubing, petrochemical reactors and structural columns where code-compliant pressure containment is required. Buyers typically specify normalized or hot-finished condition, with third-party inspection by agencies such as SGS or TUV for critical projects. The supplier lists FOB and CIF as available Incoterms, though exact port options and container loading protocols must be confirmed directly with Wuxi Dexin Steel Tube Co., Ltd.

Wuxi Dexin Steel Tube Co., Ltd maintains its registered address at 20-floor Mingzhu Plaza, 8 Dachengxiang Zhongshan Road, Wuxi 214000, Jiangsu Province, China. The supplier is classified as an imported-tier account on the platform with a harbor trust designation. The response rate is recorded at 0.00% with zero average response hours, indicating no historical messaging data is available through the platform channel. Buyers should initiate direct contact to assess current responsiveness and sales engineering support.

The listing presents Wuxi Dexin as a steel tube manufacturer with multi-standard capability spanning ASTM, GB, DIN and JIS requirements. No verified production capacity, mill equipment, annual turnover, workforce size, or client reference list is provided in the source material. The company does not disclose ISO 9001, API or other quality system certifications in the available data. Importers are advised to request a current quality management system certificate, mill test report sample, and factory audit report before committing to a first order.
