The mechanical qualities, durability, and toughness of HT Safe derive from the raw material polypropylene (PP). This is due to the special molecular structure and the density of the material across its vast spectrum of pipes and fittings, of 0.9 to 1 gm / cm3 . This significantly adds to durability, as well as long-term thermal and chemical stability, providing pipelines with an extremely long lifetime. HT Safe has a smooth inner surface that prevents scaling and incrustation that provides for outstanding hydraulic characteristics of the piping system.
