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
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.
Customized solution package
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 the conception phase through to the successful completion of your project.
SAERTEX-LINER UPgreen: CO2-optimized
The climate-friendly manufacturing process for our UP resin systems saves an average of 250,000 kg CO2 per quarter. On request, we can provide you with a certificate showing the CO2 savings achieved by your projects.
