Multilayer Composite Pipe (MLCP) PERT pipe

Features, Advantages & Benefits

• A 100% oxygen Barrier – an important feature in protecting the primary equipment in a heating system.

• Formstability – the ability to form tight bends or shapes by hand without the pipe attempting to spring back.

• MLCP has the lowest expansion rates of any plastic pipe. The expansion rates, at  50 deg c (Please put oc instead of deg c Thanks) pex is 10 times higher and PB is 8 times higher.

• Strength, the single pass, complex extrusion technology which produces 5 layer MLCP has much higher ultimate mechanical strength and the aluminium layer provides much better fire protection than ordinary plastic pipes.

Multilayer Composite Pipe has become a generic phrase for 5 layer PERT or PEX pipes with a core layer of aluminium. Most of the patent control is in the weld technology which, in the case of the PERT pipe that UK Underfloor Heating supplies , is an overlapped cold ultrasonic weld. Neatly all other manufacturers use a laser “BUTT” weld, which while as strong as the overlap it inhibits the bending and reforming  qualities.
