Our core strength lies in our high-precision products that solve industry pain points and meet the strict requirements of foreign markets. We specialize in the R&D and production of 27SiMn, 20#, 45#, 16Mn and 25Mn cold-drawn cylinder tubes, with strict control over every product characteristic. Selected high-quality raw

 materials from renowned steel mills such as Tianjin Seamless Steel Mill, Baoshan Iron & Steel and Yegang ensure the inherent stability and durability of our products, eliminating internal bubbles and impurities that cause hidden losses. With advanced equipment including hydraulic cold-drawn units, boring and rolling integrated units and polishing machines, we achieve an ultra-high precision of ±0.05mm in dimensional deviation, with inner hole finish reaching Ra0.2-0.4μm and wall thickness deviation ≤3%, fully meeting H7-H9 level dimensional tolerance standards.

To guarantee consistent quality, we implement a strict 30-step quality inspection process, covering incoming raw material inspection, in-production sampling inspection, full inspection during cold drawing and final delivery inspection, using professional inner hole straightness measuring instruments to ensure that every pipe delivered is flawless. This rigorous quality control effectively solves common industry problems such as inner hole defects, liquid leakage and ellipticity, reducing maintenance costs and extending the service life of our clients’ end products.
