roadworks. Primus Line is not stuck to the host pipe, and is self-supporting with an annulus. At the ends, the Primus Line hose is connected to the existing pipe (steel, iron cast, PE or other materials), and to the pipe network, via a specially developed high-pressure connector. Primus Line features short rehabilitation times and fast recommissioning.

The Primus Line ® system was developed to solve the recurring, time-consuming and costly problem of run-down pipelines in existing buildings. Primus Line is a trenchless technology for the rehabilitation of pressure pipelines for different media such as water, gas and oil. The process is based on a flexible high-pressure hose that is specially developed for

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. Between the inner and outer layers, seamless aramid fabric functions as a static load-bearing layer. The hose is inserted into the host pipe from small construction pits, thus avoiding large
