Water is a valuable resource as a basis of life, which requires sustainable use and our protection. Primus Line® guarantees a loss-free and secure conveyance of even the most-sensitive media, such as drinking water, contaminated or polluted liquids. Simultaneously, the composite pipe protects the old pipe from the inside against abrasive particles in the water and against corrosion.

Primus Line® is suitable for the transport of the
following liquids in the water sector:

  • potable water
  • firefighting water
  • industrial water
  • sea water
  • waste water



Gaseous media represent a special challenge to trenchless pipe rehabilitation. However, an inner layer made of permeation-reducing plastics and the seamless production of up to 4,500 metres of the Primus Liner have made it possible for gas pipelines to also be renovated with Primus Line®. A monitoring pipe with a fitted valve which is affixed to the old pipeline allows the system-specific annular space to be monitored after the renovation work. The conveyed gas covers media from categories as natural gases, liquid gases, coke gases and mixed gases (for detailed information please request our Chemical Resistance Sheet).



The oil industry is facing new challenges as a result of damage to steel pipelines caused by internal corrosion. Possible leakages can cause significant environmental damage; they also mean increased costs or even loss of reputation for network operators. Primus Line® is suitable for the renovation of oil pipelines due to the medium-specific inner layer, and acts as a corrosion barrier between the transported fluid and the host pipe. The conveyed fluid covers media from categories as crude oils, fuel oils, oil slag and other refined products (for detailed information please request our Chemical Resistance Sheet).
