Orders have already been placed for the new diameters of 630mm and 500mm by Severn Trent Water and Welsh Water, respectively, and Uponor says the new sizes are creating a lot of interest, particularly for areas presenting unique engineering challenges, and for projects where traffic flow must be maintained during works. ProFuse is Uponor’s award-winning PE 100 pipe, capable of operating at up to 16bar SDR 11 pressure at 500mm diameter. It has been designed to offer the installer the advantages of secure pipe protection both before and during installation, and the peelable outer skin is intended to ensure a perfect surface for electrofusion jointing and tapping tees. As the manufacturer has already shown in the gas industry, good-quality electrofusion joints, improving both the performance and time-savings for electrofusion fittings, all contribute towards protecting initial asset value. Jointing times at diameters of 500mm are said to be reduced by half using the ProFuse method.
