ARCO PEX/AL/PEX Multilayer Pipe D20x2mm

The ARCO PEX/AL/PEX multilayer pipe with a 20mm outer diameter and 2mm wall thickness is a high-quality solution engineered for modern heating and plumbing installations. This pipe features a composite construction that integrates the flexibility of cross-linked polyethylene with the structural integrity of an aluminum core, providing a robust and reliable conduit for water distribution. Its design ensures excellent thermal resistance and serves as an effective oxygen barrier, which is essential for maintaining the longevity of heating system components.

Advantages

The primary benefit of this multilayer pipe is its unique combination of materials, which allows for easy bending and shaping during installation while maintaining its form without spring-back. The aluminum layer provides exceptional dimensional stability and prevents oxygen diffusion, which helps protect metal components in heating circuits from corrosion. Furthermore, the smooth inner surface minimizes pressure loss and prevents scale buildup, ensuring efficient flow rates throughout the lifespan of the system.

Suitable for

• Radiator heating systems
• Underfloor heating installations
• Residential water supply networks
• Commercial plumbing infrastructure

This pipe may not be suitable for applications involving exposure to direct sunlight for extended periods, as UV radiation can degrade the outer polyethylene layer. It is also not intended for use in systems where operating pressures or temperatures consistently exceed the manufacturer's specified limits.

Key specifications

• Outer diameter: 20 mm
• Wall thickness: 2 mm
• Material: Polyethylene (PE) and Aluminium
• Working pressure: 9.8 atm
• Flexibility: High
• Color: White
• Length: 100 m

Installation should be performed by qualified professionals using compatible fittings designed for multilayer pipe systems. Ensure that the pipe is cut squarely and the ends are properly deburred and calibrated before inserting them into the fittings to guarantee a secure, leak-free connection. Avoid sharp kinks during installation and follow the recommended bending radii to maintain the structural integrity of the aluminum core.

What to consider before purchase

• Verify the compatibility of your existing fittings with 20mm multilayer pipes.
• Ensure the pressure and temperature requirements of your project align with the 9.8 atm rating.
• Confirm the total length required for your installation to minimize unnecessary joints.

Usage recommendations: Always use appropriate pipe cutters and calibration tools to prepare the pipe ends. Protect the pipe from mechanical damage and extreme heat sources during and after installation.
