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.
Primus Line® - the prime solution for pipes
Primus Line® is a flexible sliplining solution for the trenchless rehabilitation of pressure pipes. The system consists of a flexible Kevlar® reinforced liner and specially developed end fittings. Primus Line® is not bonded to the host pipe and is self-supporting. An annulus remains between Primus Line® and the host pipe. Developed by experienced engineers, the system is suitable for different media as well as various application needs and has already proven itself in numerous projects.
Primus Line® is produced in nominal diameters from DN 150 to DN 500. The liner 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.
Due to its multi-layered structure and very small wall-thickness, the Primus Liner provides both flexibility and ultra high material strength.
Outer Layer: Abrasion-resistant PE sheath
Kevlar®-Fabric: Seamless woven aramid fibres
(single-layer or double-layer fabric design)
Inner Layer: Media-specific based on PE or TPU
Primus Line Connector
At the ends, the Primus Liner is connected to the existing
pipe using Primus Line connectors. The high-pressure connector consists of a contoured internal core and external sleeve. The external sleeve has a malleable steel jacket on the inside. A resin, which is injected through a valve on the external sleeve, forces the steel sleeve and Primus Line® into the contours of the internal core. So we obtain a durable, pull-proof connection.
The residents of Ojo de Agua have only had water approximately two days a week up until now. Pipeline bursts were almost a daily occurrence due to planning errors and malfunctions in the water network. The 19 km long pipeline, supplying drinking water to the village on the border between the pro...| » Further reading
Task In 2012, the local water provider, Empresa Municipal de Aguas de Gijón (EMA), was confronted with yearly water losses of 754,224 cubic meters at one of their major trunk mains. This reflects a 15 % water loss at the pipeline in question. The cast iron water main DN 500, which was b...| » Further reading
Task The network operator United Utilities plc and Amey plc, located in the Northern part of the United Kingdom, were confronted with a leaking sewer rising main. The ductile iron pipe was installed in the 1970s and showed significant deterioration. Pinholes were present and the wall thickness...| » Further reading
