Jingning JW Steel Co.,Ltd was established in January 2015, in charge of sales, purchasing ,export and import business.
Zhejiang Jinging Clean Steel Pipe Co.,Ltd was established in 2002 and has 16.8 million Yuan of registered capital. The company is a high-qualified stainless steel pipe corporation, specializing in R&D and production on the stainless steel seamless pipe of minor diameter and stainless steel seamless coiled pipe. In December, 2012, With the support of County technical department, We set up the Zhejiang Jingning Steel Pipe Technology Research and Development Center. In 2011, the company was awarded with the title of National Hi-tech Enterprise.Now we have 11 patents, one of which is for invention. The company has 110 staff and covers an area of 23 thousand square meters, 10thousand of which is the standard factory. At the beginning, the company produced the sanitary stainless steel pipe applicable to the industry of food, beer and medicine etc. Since 2004, we started to research and produce stainless steel seamless coiled pipe and precision instrument pipe, whose materials are TP304/304L ， TP316/316L etc and specification is OD4mm-25mm，WT0.71mm-3mm. The length of stainless steel seamless pipe in minor diameter is around 3-6.1meters, and the length of stainless steel seamless pipe could reach about 500 meters. The straight pipe is mainly exported to semiconductor corporations of instrument control system, LCD panel and solar panel for transporting gas. Coiled pipes are used on the pipeline of heat-exchange coiled pipes, fluid and gas, and they are also suitable for the hydraulic control pipeline of oilfield drilling platform and ships, etc.
Now we have many kinds of production equipments, two sets 60# two-roll cold-rolling mills, one set 30# two-roll mill, four sets muffle tube bright annealing furnaces, 20 sets cold-draw pipe machines in various sizes, 20 sets internal and external polishing machines, ultrasonic cleaner and eddy current flaw detector,etc.
Jiejing entrepreneurs stick to the company mission of management innovation, technology innovation and quality first, always pursue and rely on scientific and technological progress. On the innovation of technological equipment, we cooperate with some domestic key scientific research units, aiming at updating the technology in the high-precision seamless stainless steel pipe’s light solid solution treatment, ultra long precision drawing and mirror polishing design.We hope we could further improve the production line’s automation degree and make the product’s equality into a new step.
