(3) ERW tube is high frequency resistance welding steel tube, and the common welding process is different, the weld line is from the base material of the steel belt body melted, the mechanical strength is better than the general welding.ERW stands for resistance welding, resistance welding has the ERW355 Oil & Gas Pipe Production Line ERW Carbon Steel carbon steel pipe erw structure production lineThe production pipe is straight welding pipe ,welding by High frequence Solid state Welder (for example Thermatool welder).Material is steel strip,steel coil. Pipe Production Range from 8~ 630, Thickness from 0.3mm~19mm.Pipe standard AIP,ASTM,BS,GB . The mill is not standard products, can design and produce as customer requirement.
