Quick Trade Summary: PERT-AL-PERT MLCP Underfloor Heating Pipe Coil
MEP Stock supplies professional 16mm x 2.0mm PERT-AL-PERT multi-layer composite pipe (MLCP) coils for hydronic underfloor heating, heat pump distribution, and sanitary plumbing. Featuring an internal butt-welded aluminium diffusion core sandwiched between raised temperature PE-RT polymer layers, it provides a 100% oxygen-tight barrier, zero pipe spring-back (form-stable), and 50-year design life.
Form-Stable Multi-Layer Composite Pipe for Fast UFH Laying
Laying underfloor heating pipe coils can be physically demanding if pipe material constantly tries to uncoil and spring back out of clip tracks. PERT-AL-PERT multi-layer pipe solves this with a solid aluminium core that holds its bend shape precisely without recoil, allowing heating engineers to easily form 150mm and 200mm return loops around manifold zones.
Engineering Specifications & Material Standards
| Parameter | Specification Standard |
|---|---|
| Pipe Construction | 5-Layer PERT-AL-PERT (Polyethylene Raised Temperature + Aluminium Core) |
| Nominal Dimensions | 16mm Outside Diameter x 2.0mm Wall Thickness (Standard UK UFH Pipe) |
| Oxygen Diffusion Barrier | 100% Diffusion-Tight Aluminium Core (conforming to DIN 4726) |
| Maximum Operating Pressure | 10 bar (PN10) at 70°C (Short-term peak 95°C) |
| Thermal Conductivity | 0.45 W/mK (Rapid Heat Transfer through Screed) |
| Coil Lengths Available | 100m, 200m, 300m, and 500m Continuous Coils |
| Fitting Compatibility | Eurocone 16x2mm Compression Adaptors & MLCP Press Fittings |
Step-by-Step Installation Protocol
- Coil Unrolling: Unroll pipe directly from the inside of the coil or using a pipe de-coiler to prevent spiraling.
- Fix into Floor: Secure into castellated insulation panels, clip rails, or staple directly into PIR insulation boards.
- Square Cut: Cut pipe strictly perpendicular at 90° using an approved multi-layer pipe shear.
- Calibrate & Bevel: Use a 16mm pipe reamer/calibrator to restore roundness and chamfer internal edge.
- Manifold Connection: Slide eurocone nut and split ring over pipe and tighten onto 3/4" manifold port.
Frequently Asked Questions: PERT-AL-PERT MLCP Underfloor Heating Pipe Coil
What does PERT-AL-PERT mean and why is it better than plain PEX?
It is a 5-layer composite pipe with an aluminium core that stays bent without spring-back. Plain PEX tries to recoil, requiring constant heavy stapling; PERT-AL-PERT bends effortlessly by hand and holds its exact position in castellated trays.
Does this pipe provide a complete oxygen barrier?
Yes, 100% diffusion tight to DIN 4726, preventing boiler and manifold corrosion. rming to DIN 4726, preventing oxygen ingress that causes boiler heat exchanger sludge and pump corrosion.
What size eurocone adaptors do I need for this pipe?
Requires standard 16mm x 2.0mm Eurocone (3/4" female) connectors. matching standard stainless steel UFH manifolds.
Can this pipe be used with screed and dry-mix systems?
Yes, suitable for traditional sand/cement screed, liquid anhydrite screed, and structural overlay boards. ds, and joist heat-diffuser plates.
What is the maximum pressure and temperature rating?
Rated up to 10 bar operating pressure and 95°C peak temperature. with a 50-year continuous service design life.
Do I need to calibrate and chamfer the pipe ends before fitting?
Yes, always use a 16mm calibrator tool to restore roundness and bevel the inner wall. preventing damage to the O-rings inside eurocone or press fittings.
