Difference Between Seamless And Erw Pipe

The welded seam of electric weld pipe is heat-treated after welding to a minimum temperature of 1,000°F or processed so that no untempered martensite remains. Such differences of erw are usually eliminated if the electric-weld tubing is heat-treated by the quenched-and-tempered process, which is mandatory for API grades L80, C90, T95, and P110. Difference between ERW, DOM and Seamless Tube Metal May 12, 2015 · This month we take a hard look at the differences between ERW, DOM and Seamless Tube. ERW (Electric Resistance Welded) The nomenclature ERW refers to a specific type of welding process that involves both spot and seam welding. Seam welding is commonly used during the manufacturing of round, square and rectangular steel tubing. The steel strip

Differences between ERW Steel Pipe and HFW Steel Pipe

High frequency welding (HFW) steel pipe is that ERW pipe produced with a welding current frequency equal to or greater than 70 kHZ. Through high-frequency current welding resistance, the heat generated in the contact objects, so the objected surface are heated to the plastic state, then with or without forging to achieve a combination of steels.
