PERT-AL-PERT Multilayer Composite Pipe (MLCP)
 coil pipe combines the best features of metal and plastic, offering high durability, flexibility, and resistance to corrosion for various plumbing and heating applications. It is available in various sizes and is a popular choice for underfloor heating and central heating systems. 
Key Features and Benefits
Durable Construction: The pipe features a multilayer structure with inner and outer layers of raised temperature polyethylene (PERT) bonded to a core of ultrasonically welded aluminum. This design ensures strength and stability while remaining lightweight.
High Performance: It can withstand maximum operating temperatures up to 95°C and pressures up to 10 bar (PN10), making it suitable for demanding applications.
Corrosion and Oxygen Resistance: The aluminum layer acts as a total oxygen barrier, preventing oxygen diffusion into the system and protecting system components like radiators and valves from internal corrosion.
Low Thermal Expansion: The pipe's thermal expansion coefficient is comparable to that of traditional metal pipes (steel or copper), which minimizes movement and potential issues caused by temperature changes.
Flexibility and Ease of Installation: The pipe's unmatched bendability and lack of shape memory make installation straightforward, even in tight or complex layouts, reducing the need for numerous fittings.
WRAS Approved: It is approved by the Water Regulations Advisory Scheme (WRAS), ensuring compliance with UK safety and quality standards for potable water installations.
Energy Efficiency: Low pressure losses and thermal conductivity contribute to significant energy savings in heating systems.
