Precision steel pipes are mainly used to produce seamless or welded products such as pneumatic or hydraulic components, such as cylinders or cylinders, because of their advantages such as no oxide layer on the inner and outer walls, high pressure, no leakage, high precision and so on. SH, no cold bending deformation, flat and no crack. Precision steel pipe mainly produces 10, 20, 35, 45, 40 cr, 42CrMo grade precision seamless steel pipe can also be consulted and supplied.
At heating time (s) = KD, D is the thickness of the workpiece, mm, K as the coefficient, and the factory data. (3) cooling. Different cooling systems are used for different tissues. It is usually cooled in static air. If the workpiece is large, it can be cooled by blowing or fog. The length is usually也许正是因为这个原因，在过去相当长的时间，另一方面，虽然有关各方已提出了许多警告，产能过剩的钢铁行业，甚至进行产业结构调整，地方政府仍然回避了铁和ST通过“变为零”等政策的对策就是鳗鱼项目；同时，为了维护相关的钢铁产能对地方GDP的贡献，有些地方还不遗余力地支持当地落后产能项目日即使他们清楚地知道一些地方钢铁项目的产量明显落后，政策倾斜。
