The general production process of seamless PLC control steel tube machine line can be divided into two types: cold drawing and hot rolling. The production process of cold rolled seamless steel pipe is generally more complicated than that of hot rolling.

　　Production process of seamless PLC control steel tube machine line:

　　1. PLC control steel tube machine line factory The main production process of hot-rolled seamless steel pipe: tube blank preparation and inspection → tube blank heating → perforation → tube rolling → steel tube reheating → fixed (reduced) diameter → heat treatment → finished tube straightening → Finishing → inspection (non-destructive, physical and chemical, Taiwan inspection) → storage.

　　To put it simply, the tube blank is now pierced by the ingot or blank into a hollow thick-walled capillary tube on the piercing machine; then the capillary tube is thinned on the elongating machine and extended into a waste tube close to the wall thickness; finally, it is rolled on the finishing mill to make the required of finished tubes.

　　2. PLC control steel tube machine line factory The main production process of cold-rolled (drawn) seamless steel pipe: blank preparation→pickling and lubrication→cold rolling (drawn)→heat treatment→straightening→finishing→round tube blank inspection→heating→piercing → Three-roller skew rolling, continuous rolling or extrusion → pipe removal → sizing (or diameter reduction) → cooling → straightening → hydraulic test (or flaw detection) → marking → seamless steel pipes in storage are made of ingots or solid billets The capillary is made by perforation, and then it is made by hot rolling, cold rolling or cold drawing.

　　PLC control steel tube machine line factory found cold rolled, cold drawn tube production for the production of small diameter thin wall, precision and profiled tubes. The production feature is a multi-process cycle process. In addition, small-roll cold-rolling mills have also been developed.
