With its inner layer made of lowly permeable thermoplastic polyurethane (TPU) the G-Liner makes for a safe operation of gas pressure pipelines after a trenchless rehabilitation.

Primus Line® is referenced in DVGW VP 643 for the trenchless rehabilitation of gas high pressure pipelines with operating pressures over 16 bar.

The Primus Line G-Liner is suited for operation with the following gaseous media:

  • Natural gas
  • Coke gas
  • Methane
  • Propane
  • Butane
  • Nitrogen
  • Pressurised air
  • Carbon dioxide
  • Carbon monoxide
  • Oxygen

You are thinking about using the G-Liner for other gases than the ones listed? Please contact our engineers.
