ZEWO Metal composite pipe «Sanitary»

Quality perfectly coated

The high-quality ZEWOTHERM metal composite pipe is a product of the latest generation, which is manufactured from polyethylene using the most modern production technologies in polymer processing. It combines the advantages of a plastic pipe with those of a metal pipe, it is equally flexible and robust, extremely pressure and heat resistant, hygienic and easy to install. The bending-stable aluminium jacket guarantees 100% oxygen and water vapour diffusion tightness and other gaseous substances. This barrier layer protects against possible transmission of odour and corrosion, which over time could cause damage to the system. The smooth surface also makes the inside of the pipe unaffected by normal elements present in the water, eliminates friction points and prevents deposits that could lead to subsequent corrosion.

The 5-layer metal composite pipe consists of a base pipe extruded from temperature-resistant polyethylene. In the co-extrusion process, a thin adhesive layer (primer) is applied on the outside and a 0.2 mm thick aluminium layer is butt-welded and calibrated to the inner pipe. In the coating process, a further adhesive layer and outer top layer of polyethylene is then applied. This uniform pipe structure with minimised thermal expansion ensures a permanent connection due to the two adhesive layers. The combination of plastic and aluminium makes this pipe permanently durable and safe.

In combination with the press-fitted connectors, this results in a reliable, certified system for the installation of heating and drinking water systems.

Fields of application
