Zhangjiagang Tubes China Co., Ltd. is united with Wuxi Beilai Group and Wuxi Jiangnan High Precision Cold-drawn Pipe Co., Ltd. We are engaged in researching and developing Cold-drawn gas cylinder tubes and honed steel tubes.

We are the agency of TPCO and Hengyang Valin Steel Co., Ltd., so, it is convenient for us to get the raw material.

High precision cold-drawn tube is one of the Eighth Five-year Plan state-level new products, cooperated with Beijing Scientific and Technical University under organization and leadership of Ministry of Metallurgy.

High-pressure gas cylinder tubes are widely used for making cylinder for pressured oxygen, hydric, and CNG, also for accumulator in hydraulic system and shell for energy-source storage. We supply the raw material as 37Mn, 34CrMo4 etc, the standard accordance with JIS G 3429 and GB/T 18248.

Honed steel tubes are widely applied to hydraulic and pneumatic cylinders for engineering machineries, cylinders for petroleum suction pumps, shells for micro-motors, driving shafts for vehicles and conveying roller pipe for transporting textiles, printing and dyeing materials, glass, as well as precision steel pipe in other fields. Our company has one of the most advanced quality management systems in the steel tube industry and its products meet both national and international quality standards.

The company has complete equipment and excellent technology, and possesses 250t, 150t, 65t, 40t, 20t drawing machine sets, LD-100, LD-80, LD-60, LD-30 precision cold rolling mills, up-to-date internal scrapping roll-finishing and two sets of fully enclosed box-type electric heat treating furnaces, with which it organically combines cold drawing, cold rolling, heat treatment and conventional cutting operation into one line to produce high quality products. The products include specifications of 20-500length12M, surface finishing quality up to 0.2um-0.8um, and all conform to standards GB8713-88-GB3639-2000. For specific specifications and materials: 20# 45# 16Mn 27SiMn, talks about cooperation are welcome. Besides, the company is equipped with perfect physical and chemical test facilities and quality assurance system, including carbon, sulfide, phosphor, manganese and silicon chemical analyzing apparatus, 60t universal tension tester, hardness tester and roughness tester.
