Huliot Multilayer PE-RT/AL/PE-RT pipes are part of a new generation of pipes where the advantages of metal and plastic pipes converge, minimising the inconveniences of both. The aluminium blade gives the pipe a very important property the ability to resist to expansion. As the polyethylene and aluminium pipes are fixed, pipe expansion is reduced as the aluminium expansion factor is low. Multilayer system is the perfect solution for drinking water distribution, heating/colling applications, HVAC systems and industrial applications; system is reliable, long-lasting, easy to install and cost effective.
This pipe is made up of five layers distributed as follows:
1st PE-RT type II layer
2nd Adhesive layer
3rd Overlapping aluminum welded by ultrasounds or aluminium butt welded by laser
