## Long description

The U-TUBE PEXa-EVOH pipe with an 18x2mm diameter is a professional-grade solution for modern heating and plumbing installations. Manufactured from high-quality cross-linked polyethylene, this pipe features an integrated EVOH oxygen barrier that effectively prevents oxygen diffusion into the system. This protective layer is essential for maintaining the integrity of metal components, such as boilers and radiators, by significantly reducing the risk of corrosion. The 500-meter coil offers extensive coverage for large-scale projects, providing a reliable and durable piping solution for both residential and commercial applications.
Advantages
The primary benefit of this PEXa pipe is its exceptional flexibility, which allows for easy installation even in tight spaces or complex layouts without the need for excessive fittings. The cross-linked structure provides superior thermal resistance and mechanical strength, ensuring the pipe can withstand demanding operating conditions over a long service life. Furthermore, the EVOH barrier serves as a critical safeguard for the entire heating circuit, promoting system longevity and consistent thermal efficiency by preventing sludge buildup caused by oxidation.
Suitable for
Underfloor heating systems
Radiator heating connections
Domestic hot and cold water distribution
Commercial building climate control systems
This pipe may not be suitable for applications involving exposure to direct sunlight for extended periods, as UV radiation can degrade the material over time. It is also not intended for use in systems where operating temperatures or pressures consistently exceed the manufacturer's specified limits.

How to use
The pipe should be uncoiled carefully using a decoiler to prevent kinking or twisting during installation. It can be cut to the required lengths using specialized pipe cutters to ensure clean, square edges. Connections should be made using compatible fittings designed for PEXa piping systems, ensuring that all joints are properly secured according to the fitting manufacturer's instructions. When installing in concrete screeds, ensure the pipe is protected from sharp objects and that proper expansion joints are utilized.
What to consider before purchase
Verify the compatibility of your existing fittings with 18x2mm PEXa pipes.
Ensure the system operating pressure and temperature do not exceed 15.7 atm.
Calculate the total required length to ensure the 500m coil is sufficient for your project.
Confirm that the installation environment is protected from direct UV exposure.
Usage recommendations: Always perform a pressure test on the completed system before covering the pipes with concrete or wall finishes to ensure all connections are leak-free and secure.
