SAERTEX-LINER® GAS

The WRc-certified solution for the trenchless rehabilitation of gas supply lines. Pressure-resistant, fully structural and more climate-friendly.

Pressure-resistant, fully structural and CO2-optimized: The WRc-certified SAERTEX-LINER GAS is the first choice for the trenchless rehabilitation of gas supply lines using the UV-CIPP process. It comes in two designs, each optimally matched to the specific application:

  • Type S+: low-cost alternative for low operating pressures up to 1 bar
  • Type S+XR: to resist higher pressures

BenEfits

WRc-certified for gas applications

Our SAERTEX-LINER GAS is certified by the independent Water Research Center (WRc) for the rehabilitation of steel and cast-iron gas supply lines. In addition to mechanical tests, the GRP pipe liner also fulfills the requirements for permeability and chemical resistance against a wide range of gases.

High flow rate

Smooth surfaces coupled with low wall thicknesses relative to diameter maximize flow rate in supply pipes.
