Compared to standalone PE poly pipe, this piping system offers a higher pressure and temperature rating. The PE lining provides a smooth internal surface, reducing friction and enhancing flow characteristics. Acu-Steel offers a range of pipe sizes, fittings, and accessories to meet different project needs.

The PE-lined steel pipes are created by inserting a PE liner inside the steel pipe. Before insertion the PE liner has a larger outside diameter than the inside diameter of the steel pipe. The PE liners outside diameter is mechanically reduced then pulled through the steel host pipe and left to return to its original outside diameter. This then forms a tight/compressed fit as the PE liner expands inside the steel pipe and results in the pipe being restrained by friction throughout its entire length, holding it in place and resisting the usual thermal expansion and contraction of the PE poly pipe.

The Liner is then flanged with PE stub ends that are butt welded into position.
