ERW Pipe. All Carbon steel pipe such as Casing pipe and Tubing pipe made to API specifications uses seamless or electric-weld supplying processes. There are many Differences between Seamless & ERW Pipe. The main Difference is that the Seamless Piping is suppliers by hot-working steel or, if necessary, by subsequently cold-finishing the hot-worked product to produce the desired shape, dimensions, and Difference between erw and saw steel pipe, Sunny Steel ERW is a electric-resistance welded steel pipe, Resistance welded steel pipe is divided into exchange of welded steel pipe and DC welded steel pipe in two forms. AC welding in accordance with different frequencies are divided into low-frequency welding, IF welding, welding of ultra-IF and high-frequency welding.
Sep 17, 2020 · High-frequency straight seam resistance welded steel pipe, abbreviated as ERW, is a hot-rolled coil that is formed by a forming machine, and uses the skin effect and proximity effect of high-frequency current to heat and melt the edge of the tube blank, and press it under the action of a squeeze roller Welding to achieve production.At present, in the world's output of welded steel pipes, the ERW Steel Pipes:Electric resistance welding at a glanceSunnySteel is a merchant exporter and supplier of alloy steel pipes and alloy steel tubes used for many different purposes. Seamless steel pipe Sunny Steel provide a wide range of steel products as Steel pipes, Seamless tube and seamless pipes.
