ASTM A106, ASTM A53, API 5L Gr.B Electric Resistance Welded Tube

ERW pipes mean 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. ERW steel pipes and tube are available in various qualities, wall thicknesses, and diameters of the finished pipes.

All the incoming coils are verified based on the mill test certificate received from steel mill for their chemistry and mechanical properties. The forming stage of ERW pipe begins with a single-width strip. The width of the strip is roughly equal to the perimeter of the pipe to be produced. The edges of the coil are sheared to pre-specified widths in slitting line. The process involves uncoiling & levelling of coils and processing the same. The lead end of each coil is squared by shearing operation for threading into the mill. Then this end is joined with the coil end of the outgoing coil to maintain continuity in production and reduce losses.
