The Primus Line® system

Primus Line® is a flexible sliplining solution for the trenchless rehabilitation of pressure pipelines referenced in EN ISO 11295:2018-06. The system consists of a flexible aramid-reinforced liner and specially developed end fittings. The liner is self-supporting and not attached to the host pipe – an annular space remains.

Developed by experienced engineers, the system is suitable for different media as well as various other applications and has already proven itself in numerous projects: besides the rehabilitation of damaged pipelines, it can also be used to increase the pressure within existing systems, protect them from corrosion and build bypass systems or stand-alone solutions.

The Primus Line® system is certified in many countries – for example Australia, the USA, Germany, Canada and Israel – and meets the highly demanding standards for the transportation of drinking water worldwide. Primus Line® is available in nominal diameters ranging from DN 150 to DN 500.

The company

Rädlinger primus line GmbH is the manufacturer of the Primus Line® system, an innovative relining solution for the trenchless rehabilitation of pressure pipes for different applications such as water, gas and oil.

Clients benefit from long insertion lengths of up to 2,500 m in one single step and the product’s ability to traverse bends of up to 45 degrees.

Small construction pits, short rehabilitation times and the low level of impact on the environment, make Primus Line® the ideal technology for the rehabilitation of defective lines in sensitive environments. Developed by experienced engineers and more than 20 years in business, the system is suitable for various application needs and has already proven itself in numerous projects.
