Our mild steel pipe is produced on fully automatic imported plant from high-grade prime steel coil, and is drawn on for everything from fire-fighting mains to high-pressure steam lines. Every length is hydro-tested before it leaves the mill.

The range runs from 1/2" through 16" nominal bore in Schedule 10, 20, 40 and 80, and is available in both Grade A and Grade B to ASTM A53 and ASME B36.10M. Wall thickness runs to 12 mm, which is the ceiling the mill rolls to; heavier sections are supplied against order. Straightness, wall thickness, weight and length are all held to the standard, and mill test certificates are issued with every consignment.

Where a project calls for a specification other than ASTM — JIS, DIN, EN, BS, ISO or PS — we manufacture against it on enquiry.
