U-TUBE PEXa-EVOH Pipe 20x2mm, 500m

The U-TUBE PEXa-EVOH pipe with a 20x2mm diameter is a high-performance solution engineered for modern heating and plumbing infrastructure. Constructed from premium cross-linked polyethylene, this pipe offers exceptional durability and thermal resistance. The integrated EVOH oxygen barrier layer is a critical feature that prevents oxygen from permeating the pipe walls, thereby significantly reducing the risk of corrosion in metal components such as boilers, pumps, and valves within the heating circuit.

Advantages

This pipe stands out due to its superior flexibility, which simplifies the installation process even in tight spaces or complex layouts. The cross-linked structure provides excellent resistance to high temperatures and mechanical stress, ensuring a long service life for your heating system. Its smooth inner surface minimizes pressure loss and prevents the buildup of scale or deposits, maintaining efficient flow rates over many years of operation. The inclusion of the oxygen barrier makes it an ideal choice for closed-loop systems where component longevity is a priority.

Suitable for

• Underfloor heating systems
• Radiator heating connections
• Residential plumbing installations
• Commercial building climate control

This pipe may not be suitable for applications involving exposure to direct sunlight, as UV radiation can degrade the material over time. It is also not intended for use in high-pressure steam systems or environments where temperatures consistently exceed the manufacturer's specified thermal limits.

Key specifications

• Outer diameter: 20 mm
• Wall thickness: 2 mm
• Length: 500 m
• Material: Cross-linked polyethylene (PEXa) with EVOH barrier
• Working pressure: 15.7 atm
• Color: White

How to use

The pipe should be installed by qualified professionals using compatible fittings designed for PEXa systems. When uncoiling the 500-meter length, use a decoiler to prevent kinking and ensure the pipe remains straight during the laying process. Secure the pipe using appropriate clips or staples according to the specific design requirements of your floor heating or radiator layout. Ensure that all connections are tightened to the manufacturer's torque specifications to prevent leaks.

What to consider before purchase

• Verify the compatibility of your existing fittings with 20x2mm PEXa pipes.
• Ensure the 500-meter length is sufficient for your project area to minimize unnecessary joints.
• Check that the operating temperature and pressure of your system do not exceed the pipe's rated capacity.

Usage recommendations

Always store the pipe in a cool, dry place away from direct sunlight until the moment of installation to maintain material integrity. Avoid bending the pipe beyond its minimum radius to prevent structural damage.
