ERW Welded Steel Pipe means Electric Resistance Welded Pipes and the raw material is carbon steel, mainly character is the welding beam is smooth, two end no burr, hardness is very strong, so some special material can be use for machine components. It is used in building engineering, construction material, scaffolding, line pipes, underground transfer assemble structural, chemical liquid transfer, oil and gas transfer etc. Outside surface can be treated by galvanized, oil, black painting, 3pe or as customer request. Normal usage validity time will be around 5-10 years.
