Electric resistance welded (ERW) pipe is made from steel coil and the weld seam runs parallel to the pipe.The width of the coil is the same as the circumference of the pipe so diameters are limited to 24 inches.However,because the manufacturing process is fast,it is ideal for large production runs of small (<= 24 in.) diameter sections. results for this questionWhat ' s The difference between ERW and SpiralWeld pipe?What ' s The difference between ERW and SpiralWeld pipe?Rolled and welded pipe can be made in diameters of up to 16 feet and over 2.0 inches in thickness.Spiralweld pipe,like ERW pipe,is also manufactured from steel coil.The difference is the coil is wound at an angle,so the weld runs around the outside of the pipe in the shape of a helix.ERW Pipe Electric Resistance Welded - Nucor Skyline
