Based on its particular advantages, the egeLiner®, a preformed pipe for close-fitlining, was the investor’s first choice, since this particular type of rehabilitation allows for continued utilization of the preexisting pipeline.
The approach represents a close-fit technology in accordance with EN ISO 11295. The egeLiner® PE 100-RC is resistant to stress cracking and has long been used in the gas industry in view of the special safety requirements involved and previous positive experience.
The result of the rehabilitation is a PE 100-RC pipe featuring the same pressure class as the surrounding steel pipe which provides additional protection of the inner PE pipe from potential mechanical damage.
The installation was carried out by Zepris s.r.o., a subsidiary of Ludwig Pfeiffer, a firm specializing on trenchless rehabilitation methods for drinking water, sewage and gas pipes. Together with this important egeplast partner in Czechia, many joint projects with large-diameter pipes and in special civil engineering have been performed successfully and according to professional standards by qualified staff. The egeLiner® system was supplied by Gerex Liberec as egeplast’s exclusive sales partner in Czechia.
