创新的5层塑料管制造工艺，应用独特的挤压工艺，可以一步完成5层结构的复合，将阻氧层(EVOH)永久可靠地黏合在PE-X内层和PE外层之间。

 five-layer oxygen blocking tube has better heat resistance, humidity resistance and wear resistance because of the structure of the intermediate oxygen blocking layer, providing better reliability and durability assurance, suitable for low-temperature radiation ground heating system and radiator connection system, Perfect for construction sites with harsh construction conditions.

The innovative five-layer plastic pipe manufacturing process and the unique extrusion process can complete the five-layer structure compounding in one step. The oxygen barrier layer (EVOH) can be permanently and reliably bonded between the PE-X inner layer and the PE outer layer.

Because of the unique manufacturing process, the five-storey structure has better deformation resistance and external stress resistance.

Special anti-aging agents and stabilizers can maintain the permanent flexibility of pipelines and ensure high thermal stability.

Because of the outer protection characteristics of pipes, the installation is more flexible and safe, and the installation of plumbing workers is faster and more convenient.
