Primus Water, Sewer & Gas Lining

Primus Line® is a trenchless technology for the rehabilitation of pressure pipelines for different media such as water (NSF 61 Approved), sewer, gas and oil. The process is based on a flexible high-pressure hose, which is specially developed for the connection technique of the system.

Due to its multi-layered structure and very small wall-thickness, the Primus Line hose provides both flexibility and ultra high material strength. The inner layer of the hose can be selected for the specific media.

The outer layer – regardless of medium – is made of wear-resistant PE. Seamless Kevlar aramid fabric is between the inner and outer layers, functioning as a static load-bearing layer. Primus Line® is produced in nominal diameters from 6 inch to 20 inch.

The hose is inserted into the host pipe from small construction pits – thus avoiding large roadworks. Primus Line® is not attached to the host pipe and is self-supporting. An annulus remains between Primus Line® and the host pipe. Via a specially developed high-pressure connector on each end, the Primus Line hose is connected to the host pipe (steel, iron cast, PE or other materials), and thus to the pipe network.

Primus Line® has short rehabilitation times due to long insertion lengths and rapid recommissioning, and thus represents not only an inexpensive alternative to open rehabilitation, but also a high-quality method for the renewal of pressure pipes.
