    无缝钢管分为冷拔和冷轧两种工艺,冷拔无缝钢管是在无缝钢管管坯的基础上直接上冷拔机冷拔加工,它的工艺简单,产量较高,但外表粗糙。而冷轧是在无缝钢管管坯的基础上酸洗磷化后在上冷轧机上精轧,精密度高里外光亮(也就是我们常说的精密光亮冷拔无缝钢管)但是产量较低。精密无缝钢管常用牌号10、20、35、45;在电力、石化、船舶、航天、轴承、气动元件、油缸、锅炉设备、汽车等行业中大量应用;生产规格外径4—200mm,壁厚0.5—12.5mm。

    Seamless steel pipe is divided into two processes: cold drawing and cold rolling. Cold drawing seamless steel pipe is directly processed by cold drawing machine on the basis of seamless steel tube billet. Its process is simple, its output is high, but its appearance is rough. Cold rolling is finished on the upper cold rolling mill after pickling and phosphating on the basis of seamless steel tube billet. It has high precision, bright inside and outside (that is to say, precise and bright seamless steel tube) but low output. Precision seamless steel pipe commonly used brand 10, 20, 35, 45; in power, petrochemical, shipping, aerospace, bearings, pneumatic components, cylinders, boiler equipment, automobile and other industries, a large number of applications; production specifications outside diameter 4-200 mm, wall thickness 0.5-12.5 mm.
