SLM® 3.0
Protective piping system for damage-free installation
SLM® 3.0 piping system is a patented, multi-layered protective piping system of the latest generation. When installed by means of alternative installation techniques, the protective pipe ensures the grid operator longevity and efficiency. Engineering offices and contractors verify flawless planning with this piping system.

additional protective layer made from PEplus
inner pipe made from PE 100-RC
Product features
- The additive protective coating (wearing surface) enables damage-free installation of the new pressure pipe.
- Welding according to DVS standards: butt welding without cut-back is possible, Tapping on undamaged pressure pipe
- Trenchless installation techniques are possible without shortening the durability due to damages or reduction of the safety factor.
-
One piping system for all installation techniques (open trench and trenchless installation)
