SAERTEX-LINER® GAS

SAERTEX-LINER® GAS

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. Two liner options are available, each designed to match the specific application:

  • Type S+: a cost-effective alternative for low operating pressures up to 2 bar
  • Type S+ XR: engineered to accommodate higher pressures up to 33 bar

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.

LOW WALL THICKNESS OPTIMIZES HIGH FLOW RATE

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

CUSTOMIZED SOLUTIONS WITH SUPPORT SERVICES

You, too, can benefit from our wide range of additional services. Our experienced experts and engineers provide support to ensure the smooth progress of your construction project from conception to completion.

SAERTEX-LINER® UPgreen: CO2-OPTIMIZED

The climate-friendly manufacturing process for our UP resin systems saves an average of 250,000 kg of CO2 per quarter. On request, we can provide you with a certificate showing the CO2 savings achieved by your projects.
