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 Seamless and Welded/ERW PipesWelded steel pipe is manufacturing with steel strip or steel plate, through bending and different welding processes. Performance and Usage: Seamless steel pipe has better pressure capacity, strength is higher than ERW welded steel pipe. So it is widely applied in high pressure equipment, and thermal, boiler industries. Generally the welding hot rolled erw welded steel pipeDifference Between Seamless and Welded/ERW PipesWelded steel pipe made by hot rolled coil as raw material, the surface quality of coil is just the pipes surface quality, and easy to control.The surface of hot rolled coil have high quality. So Welded steel pipe surface quality is much better than seamless steel pipe.
