erw weld steelpipe
Our products such as API 5L ERW steel pipe, seamless steel pipe, SSAW steel pipe all have API 5L, API 5CT, EN10219, EN10217, etc international quality system certification. Development of Advanced Electric Resistance Welding of ERW Linepipe Electric resistance welding (ERW) pipes are manu-factured by continuously roll-forming hot coil material into a pipe shape, and butt-welding the weld seam after heating/melting the coil edges using the Joule heat gen-erated by passing a high frequency current through the edges. At the seam of the ERW butt weld (hereinafter,
In a welded pipe, the seam or the weld-joint is the weaker part of the pipe limiting the strength of the pipe to the strength of the weld-joint. Generally, the process of supplying weld pipe begins with the rolling of a steel coil to the desired gauge thickness to form a flat strip. Difference between ERW, DOM and Seamless Tube Metal

Differences between ERW Steel Pipe and HFW Steel PipeERW steel pipe is manufactured through low or high frequency resistances Electric Resistance. 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.
Hot-dip Galvanized Coated ERW Steel Pipe One of the most widely used materials on Earth, steel provides outstanding strength, toughness, and durability. Steel pipe is a versatile, cost effective solution for a broad range of applications, including: Stainless Steel ERW Pipe SS 304/316 Welded Pipe The Erw Stainless Steel Pipe can range from smaller sizes up to 24 inches outer diameter. Our Erw SS Pipes are manufactured according to international standards and are tested for quality.We also supply Erw Stainless Steel Tube & Stainless Steel Electric Resistance Welding Pipes in other material grades than the 304 and 316 grades of stainless steel. Sturdy, Stainless erw weld steel pipe for Industry Uses The erw weld steel pipe you can find on the site are generally built using hot-dipped technology to prevent rusting and weakening of the structural elements. With seamless welding quality, these erw weld steel pipe are annealed with nitrogen protection and are polished with utter professionalism. These products are made of robust materials such as carbon steel, stainless steel, galvanized surface-treated iron
