• Natural gas • Sweet gas

• Sour gas • Mixed gas

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 Line hose have made it possible for gas pipelines to also be renovated with Primus Line®.

A monitoring pipe with a fitted valve that is affixed to the old pipeline allows the system-specific annular space to be monitored after the renovation work.

The oil industry is facing new challenges as a result of damage to steel pipelines caused by internal corrosion. Possible leakages might 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.
