Resistance welding has the characteristics of high production efficiency, low cost, material saving, and easy automation. It is used to transport oil, natural gas and other vapor and liquid objects, and can meet various requirements of high and low pressure.
When electric resistance-welded carbon steel pipe was exposed to aggressive waters, grooves caused by the redistribution of sulfide inclusions along the weld line were formed in the weld. The material at the bond line is anodic to the surrounding material and the result is a V-shaped groove with the apex of the V centered on the bond line. Electric Resistance Welded Pipe, ERW Steel Pipes, Electric Electric Resistance Welded Pipe ERW pipes means Electric Resistance Welded Pipes. ERW steel pipes and tubes are used. ERW steel pipes and tubes are used in various engineering purposes, fencing, scaffolding, line pipes etc. ERW steel pipes and tube are available in various qualities, wall thicknesses, and diameters of the finished pipes.
Electric resistance welded (ERW) pipe is manufactured by cold-forming a sheet of steel into a cylindrical shape.Current is then passed between the two edges of the steel to heat the steel to a point at which the edges are forced together to form a bond without the use of welding filler material.Initially this manufacturing process used low frequency A.C. current to heat the edges.

5.4 The weld seam of electric-resistance welded pipe to Grade B pipe shall be heat treated after welding to a minimum temperature of 1000 °F (540 °C) or processed in such a manner that no untempered martensite remains. 6. Chemical Composition 6.1 The steel shall conform to the requirements prescribed in Table 2, based on the heat analysis. Standard Specification for Electric-Resistance-Welded Low The steel may be cast in ingots or strand cast and the pipe shall be made by electric resistance welding. Pipe furnished in the as-welded condition shall be normalized at a temperature above the upper critical temperature. Cold-drawn pipe shall be normalized after the final cold-draw pass.
Electric Resistance Weld Standard and Line Steel Pipe Our high frequency electric weld (ERW) line pipe and standard electric resistance weld pipe products are produced by continuously forming coiled hot rolled strip into a tube and welding the longitudinal seam using high-frequency electric resistance welding. black ERW steel pipe - Longwin Unisteel Companyblack ERW steel pipe ASTM A500 Black steel pipe ERW pipe cold formed from a ribbon of steel pulled through a series of rollers and formed into a tube which is fused through a electric charge.Double Submerged Arc Welded (DSAW) steel pipe is available in straight and spiral welded formats and used in a variety of applications.
