Outer Protective Layer

Plastic pipeline for bedding in earth:

For bedding in earth the version serves, where as a "protection pipe" the plastic pipe made of HD-PE is used. This layer reinforces the heat insulating material. The protection pipe HD-PE meets EN 253.

Spiro-pipeline for overground distribution systems:

It forms a protective coat of surface distribution systems. According to environment character various kinds of materials may be used. The basic version – galvanized metal sheet 0.6 mm thick. Advantage of this version is not only a qualitative insulation, but above all considerably higher robustness in comparison with the additionally fixed cover sheets.
Material – galvanized steel 11 321.21 (eventually stainless steel, Al).
