About us

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 Hose

Primus Line Hose

Due to its multi-layered structure and very small wall-thickness,
the Primus Line hose 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

Primus Line Connector

At the ends, the Primus Line hose 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.

Installation

Installation

Primus Line® is produced in nominal diameters from DN 150 to DN 500.
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.
