OD-controlled pipe is dimensioned by outside diameter and wall thickness. Several sizing systems are used including IPS, which is the same OD as IPS steel pipe; DIPS, which is the same OD as ductile iron pipe; and CTS, which is the same OD as copper tubing. For flow calculations, inside diameter is calculated by deducting twice the wall

2018104 · For steel fibre reinforced concrete pipes, the crushing load shall be taken to the specified proof load, held for one minute, and the pipe inspected for any crack. The result of that inspection shall be recorded. If no crack is found the load shall then be taken to the ultimate (collapse) load and a record made of that load.

The material is steel alloy, with a wide range of options for composition. The material can include several alloying elements (for example, up to 0.4% chromium and 0.15% molybdenum, but as little as 0.0% of both). It bends and welds easily. HREW 1015: Hot Rolled Electric Welded tube, 1015 steel alloy.
