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.This allows for a lot more variation in diameter and thickness than ERW pipe.Spiralweld pipe is most commonly used for pipe diameters between 24 in.and 120 in.and for thicknesses of 1.0 in.or less. results for this questionHow is electric resistance welded ( ERW ) pipe made?How is electric resistance welded ( ERW ) pipe made?However,because the manufacturing process is fast,it is ideal for large production runs of small (<= 24 in.) diameter sections.Electric Resistance Welded (ERW) pipe is manufactured by cold forming a flat steel strip into a rounded tube and passing it through a series of forming rollers to obtain a longitudinal seam.ERW Pipe Electric Resistance Welded - Nucor Skyline results for this questionWhat is spiral steel pipe?What is spiral steel pipe?Spiral steel pipe is a coiled steel pipe made from strip coils as the raw material,which is often warm extruded and welded by an automatic double wire double-sided submerged arc welding process.The strength of the spiral welded pipe is generally higher than that of the ERW welded pipe.The difference between ERW steel pipe and spiral steel pipe - abter
