Electric Resistance Welded (ERW) Products – Square, Rectangular, Round and Oval Tubes.
ERW is a process where electrical contacts or induction coils are used to manufacture the pipe. Steel strip is uncoiled, leveled and crop-sheared. It is then trimmed on both sides at the same time to correct width and immediately fed into the forming and welding line. This strip is fed into a series of cold forming rolls, where it is formed into a tubular shape, and then joined by high frequency electric resistance welding. The resulting product has a uniform wall thickness, and the welded area is heat-treated by post annealing to ensure adequate ductility at the weld. Our ERW pipe is sourced from mills that have been audited by our experienced staff & have accreditation to international organizations such as API (American Petroleum Institute). Our stock pipe is also certified to Grade 350L0 thus enabling the pipe to be used for structural applications. Full certification is available.
Standard lengths are 6.10m or 7.32m, BlueScope Distribution can supply a range to ERW tube products, typically used in applications such as:
