Straight seam resistance welding pipe mill has features of multi specifications, advanced supporting equipment , large capacity:
Currently, there are more than 2,000 sets of ERW welded pipe mill unit in China, which a large number of small diameter welding tube mill in general level, but in recent years, dozens of new units of 219-660 ERW units reached the international advanced level, that has greatly improved our country ERW tube production line unit overall equipment and technical level. These advanced machinery adpot such as super horizontal spiral loop group units, milling machine, solid state high frequency welding, welding parameters automatically detecting, nondestructive testing, inner burr clearing, on line heat treatment, high precision sizing mill and CNC profiling flying saws and other equipment, and computer controlled flexible forming excellent (FFX) and cage forming, which can produce high grade steel line pipe, high strength structural tubes, and some special types of welding pipes instead of seamless pipe, such as oil casing, oil tube, medium and low pressure boiler tubes, cylinder tube, drive shaft pipes and so on.
