ERW Pipe | Electric Resistance WeldedElectric Resistance Welded (ERW) pipe is manufactured by cold forming a flat steel strip into a rounded tube and passing it through a series of forming rollers to obtain a longitudinal seam. The two edges are then simultaneously heated with a high frequency current and squeezed together to form a bond.

What is a Welded Steel Pipe? About Welded or ERW Steel erw welded cold rolled steel pipe

Welded pipe (pipe manufactured with a weld) is a tubular product made out of flat plates, known as skelp that are formed, bent and prepared for welding. The most popular process for large diameter pipe uses a longitudinal seam weld. Spiral welded pipe is an alternative process, spiral weld construction allows large diameter pipe to be produced from narrower plates or skelp.The Process of Creating ERW Steel Pipes | Supreme Pipe BlogThe process of creating ERW steel pipes are distinct, in that it makes use of an electrical current to weld the joints in place. In this technique, instead of having to use a welding filler to join the edges together, a non-contact induction coil is used with the help of an impeder to concentrate the current to the edges of the pipe.SAE J526 ERW Welded Steel Pipe / Low Carbon Steel High quality SAE J526 ERW Welded Steel Pipe / Low Carbon Steel Tubing For Automotive Fuel from China, China's leading welded steel pipe product, with strict quality control welding steel tubing factories, producing high quality welding steel tubing products.
