FM approved pipes and fittings are tested under extreme conditions for the application in firefighting systems.
Underground fire protection systems made of PE 100(-RC) are maintenance-free, leak-proof and resistant against:

  • Seismic activities (soil settlements)
  • Pressure surges (water hammers)
  • Resistant against abrasion
  • Point loads
  • Rapid crack propagation
  • Root penetration

 Further advantages are:

  • Corrosion free (particle free)
  • Easy to install (flexible system)
  • No incrustations (no pressure loss - low energy costs)
  • Reliable performance

Since FM approved products are tested for high quality and safety, the cost of property insurance can be reduced significantly.

By using FM approved products, a high reliability and operational safety can be expected.
