Metal-plastic pipe PERT-Al-PE

Metal-plastic pipe PERT-Al-PERT

Overview

The first inner layer is made of heat-resistant PERT polyethylene.
The second layer is a high-quality adhesive composition, which has good adhesion to both polyethylene and aluminum, and ensures a reliable connection of all layers.
The third layer is aluminum foil, which prevents oxygen diffusion and provides strength and low linear thermal expansion of the pipe. The edges of the foil are butt-welded to each other by TIG welding.
The fourth layer is a high-quality adhesive composition that has good adhesion to both polyethylene and aluminum, and ensures a reliable connection of all layers.
The fifth outer layer is made of heat-resistant PERT polyethylene.
The material PERT (Polyethylene of Raised Temperature resistance) is a heat-resistant polyethylene. This material is obtained by replacing "flat" butene in a chemical reaction with octene, which has a spatially branched structure. Subsequently, it forms side branches near the main chain, which are intertwined monomer chains.

Thanks to this structure, PERT acquires properties such as increased long-term heat resistance and increased strength, but retains the flexibility inherent in conventional polyethylene.
The advantages of metal-plastic pipes are high strength and heat resistance, resistance to corrosion, overgrowth, silting and salt deposition; high chemical resistance, resistance to mechanical damage, low roughness, gas tightness, high noise absorption capacity, low thermal conductivity, low coefficient of linear expansion, high ductility and light weight, technological and economical installation.

A distinctive feature of PERT pipes is the possibility of installation by welding.

Compliance with the passport operating conditions guarantees a 50-year service life of the products.
