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. The system consists of a flexible Kevlar® reinforced liner and specially developed end fittings.
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 degree. Primus Line® is not bonded to the host pipe and is self-supporting. An annulus remains between Primus Line® and the host pipe.
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 15 years in business, the system is suitable for various application needs and has already proven itself in numerous projects.

The system consists of a flexible Kevlar®-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 (6 inches to 20 inches).
Its multi-layer structure, as well as the small wall-thickness, make Primus Line® the ideal system for the trenchless rehabilitation of pressure pipes: Stable and secure, with diverse areas of application and high levels of efficiency. The outer layer consists of an abrasion-resistant PE sheath to protect the liner during installation. The Kevlar® fabric consists of seamless woven aramid fibres, which accommodate the operating pressure. The inner coating is fluid specific, made from PE or TPU.
