ERW219 Pipe Mill ERW Carbon Steel Tube Mill,Slitting Line

High frequency HG219 welded steel tube mill welding machine. This mill is intended to manufacture round pipe,square pipe, rectangle pipe, structure pipe as customer advise. The production pipe is straight welding pipe,welding by High frequence Solid state Welder (for example Thermatool welder).Material is steel strip,steel coil.ERW pipe, shorted forelectronic resistance welded pipe, is manufactured by cold forming the steel coil into a round cylindrical pipe. Current passes between the two edges of the steel to heat the steel to a point at which the edges are able to connect together to form a bond using the actual welding process.What's the Difference Between ERW Pipes and Seamless Pipes?Was this helpful?What's the difference between ERW pipes and seamless pipes?What's the difference between ERW pipes and seamless pipes?The biggest visible difference between ERW pipes and seamless pipes in structure is that ERW pipe has a welding seam which is produced by the welding process while seamless pipe doesn't.
