FAQ
Q: What is the structure of three-layer barrier pipe?
A: The pipe body is co-extruded from a PE-Xa inner layer, an adhesive layer, and an EVOH oxygen barrier layer, resulting in a stable structure and strong sealing.
Q: What are its main applications?
A: It is suitable for closed-loop transportation in floor heating systems, HVAC systems, water pipe systems, and solar heating projects.
Q: What is the difference between three-layer barrier pipe and ordinary PEX pipe?
A: The addition of the EVOH oxygen barrier layer provides enhanced corrosion and impermeability resistance, extending the system life.
Q: Is it easy to install?
A: Yes. It is lightweight, highly flexible, and can be rolled, making installation 40% more efficient than metal pipe.
Q: What is the packaging method?
A: The pipe is rolled with moisture-proof film or packaged to length, making it easy to store, transport, and install on-site.
