The straightness of   seamless steel tubes   has a significant impact on pipes used in precision machinery and hydraulic cylinders. High straightness accuracy can enhance the efficiency of post-processing for customers and reduce production costs. What are the factors that affect the straightness of seamless tubes?  1. Outdated straightening equipment The outdated straightening equipment, resulting in poor straightening accuracy. The straightness of seamless steel tubes after being discharged from the furnace has not significantly improved, and only visual inspection can ensure no bending. For the precision processing industry, the straightness requirements of such seamless steel tubes cannot be met, for example, for hydraulic cylinders, which have high requirements for the straightness of steel tubes and need to ensure the consistency of the inner hole. However, outdated straightening equipment is far from meeting this requirement.  Xiangjia Steel  possesses ad...

42CrMo alloy steel seamless pipe   has good permeability, high toughness and hardness. The production process of them are hot rolling process, cold drawing process and finishing rolling process. Hot rolling process: round steel material inspection - round steel cutting - round steel heating - round steel perforation - sizing - room temperature cooling - straightening - cutting ends - quality inspection - spray marking and delivery Cold drawing process: round steel perforation - pickling - cold drawing processing - quality inspection - delivery Finishing rolling process: round steel piercing - pickling - rolling mill finishing - cutting ends - quality inspection - delivery The three production processes of seamless steel pipes have their own advantages, you can choose the right production processes for your demand. Changsha Xiangjia Metal Materical Co., Ltd.  the Steel Pipe Division of ADTO GROUP, is one of the leading manufacturers of steel products in China. We specializes in...
