Straight seam welded pipe has simple production process, high production efficiency, low cost and rapid development. The strength of spiral welded pipes is generally higher than that of straight seam welded pipes. How does welding seam work?How does welding seam work?Welding seam is in longitudinal. During the ERW pipe welding processes, the electric current will make the heat when flow through the contact surface of the welding area. It will heat the 2 edges of the steel to a point that the edges can form a bond.Differences between ERW Steel Pipe and HFW Steel Pipe
HFW is required in API 5L PSL2 ERW steel pipe. According the API 5L and ISO 3183 specification, for PSL 2 pipes in welded process the HFW welding is a mandatory requirements for ERW steel pipes. As it is an improvement from the inherent problems of hardness, lack of fusion and susceptibility of stress corrosion cracking (SCC).ERW Straight Seam Round Pipe Mill Line - China Wan Run ERW Straight Seam Round Pipe Mill Line ERW stands for Electric Resistance welding.

ERW straight seam welded pipes are further divided into low frequency welding, intermediate frequency welding, ultra intermediate frequency welding and high frequency welding
Before pipe welding, pipe is formed in round shape passing through a series of driven and idler rollers of forming section. In welding section pipe is longitudinally welded by using high frequency induction welding method. Outside bead is removed and formed in shape of scrap. The weld seam is ironed and pipe passes through the cooling section.Electric Resistance Welded Pipe, ERW Steel Pipes, Electric Steel ERW Welding Pipe Mill and Straight Seam WeldedElectric Resistance Welded Pipe. ERW (Electrical Resistance Welding) pipes are manufactured by cold forming of steel coil into a round cylindrical shape are used in various engineering purposes. ERW steel pipe is formed by rolling plate and welding the seam.

But compared with the same length of straight seam pipe, its weld length increased by 30 ~ 100%, and the production speed is low. As a result, small diameter welded pipe are mostly with straight seam welding, large diameter welded pipe for the most part adopts spiral welded.The difference between straight seam welded pipe and Steel ERW Welding Pipe Mill and Straight Seam WeldedWelded steel pipes are divided into straight seam welded pipes (ERW Steel Pipe) and spiral welded pipes according to the form of welds. Straight seam welded pipe has simple production process, high production efficiency, low cost and rapid development. The strength of spiral welded pipes is generally higher than that of straight seam welded pipes.
ERW pipe machine is a special equipment for production of straight seam welded tube used in metallurgy, construction, transportation, machinery, vehicles and other industries. It uses cold rolled and hot rolled strip as raw material to produce the required specifications of round, square and rectangle tubes through cold roll forming and high frequency welding.What is a Welded Steel Pipe? About Welded or ERW Steel Steel ERW Welding Pipe Mill and Straight Seam WeldedWelded 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.
