Precision Steel Tube are produced by Cold Drawn and Cold Rolling, with very good OD and ID tolerance and smoothness ,
with very good Concentricity, Good Ovality, Good Roundess, Less Deviation, suitable for machinery and CNC machining part, for auto parts.
Cold Drawn Seamless tubing (also known as CDS steel tube. Cold Drawn Seamless tubes offer tight tolerances compared to Hot Finished Seamless tube, and offers stronger physical properties compared to other mechanical tubing.
CDW Steel Tubes is made by drawing the ERW tubes from the tube mills through a plug and die combination, mounted on the draw bench. The end tagged and annealed tubes are drawn through a closely machined die that controls the outside diameter of the tubes. At the same time the tube passes over a plug that controls the inside diameter. Further, the manufactured tubes are processed by the downstream facilities for different industry applications.

This type of support is the key project of Shanxi Province “Twelfth Five-Year Plan†led by Shanxi Provincial State-owned Assets Supervision and Administration Commission and Taizhong Coal Mining Machinery. Pingyang Heavy Industry is responsible for the design and manufacture of intelligent support, and has independent independent intellectual property rights. The bracket has advanced intelligent functions, and is equipped with electronic devices such as a controller, a sensor network, a server, a smart camera, and a communication device. The bracket can automatically couple the surrounding rock structure with complex and variable working faces, and has gesture recognition and adjustment functions. The control system has a complete self-diagnosis and fault warning function, and can also be “seamlessly†connected with the fully mechanized mining face control platform, realizing the “three machines†of the underground unmanned working face hydraulic support, shearer and scraper. Linkage control.
Pingyang Heavy Industry completed the design of intelligent hydraulic support prototype
After nearly half a year of research and development, recently, Shanxi Pingyang Heavy Industry Co., Ltd. undertook the national “Twelfth Five-Year†intelligent manufacturing special sub-project – ZYl2000/28/64D two-column shielded intelligent hydraulic support to complete the prototype design task.
