ERW Pipe

ERW Pipe

ERW (Electric Resistance Welded)
ERW steel pipes and tubes are used in various engineering purposes, fencing, scaffolding, line pipes etc. ERW steel pipes and tube are available in various qualities, wall thicknesses, and diameters of the finished pipes

Application Area:
Water pipelines
Agriculture & irrigation (Water mains, sewerage systems, industrial water lines, plant piping, deep tube-wells & casing pipes)
Gas pipe lines (Pipe lines for natural gas)
LPG and other non-toxic gas
The SW is meant for shallow water applications in a canal, natural stream, culvert, or pipe
