High Frequency Electric Weld (ERW) Line Pipe,ERW casing 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

high frequency electric weld (ERW) line pipe and standard electric resistance weld pipe products are smoothly finished and thin-walled. They are produced by continuously forming coiled hot rolled strip into a tube and welding the longitudinal seam using high-frequency electric resistance welding.

Features of ERW welded pipe products:
1.Smooth surfaces:
2.ERW steel pipe products have uniform wall thicknesses made from hot-rolled steel strip
3.Stronger, lighter walls: Abter’s higher strength, lighter gauge steel strip is fused by high frequency electric resistance welders into high toughness steel pipe that meets exacting tolerances and strength specifications.

      Seamless steel pipe is alos called CDS pipes (Cold drawn seamless pipe). It’s is used widely in maching parts, shafts, bearings, cylinders having strength of 75000 PSD tensile.
      It is a solid carbon steel rod which is pushed on to the mandrel to form the shape of tube. It is available in different sizes.
