Short Business Description

Primus Line® is used for the trenchless rehabilitation of pressurised pipelines and for the construction of freely layable pipelines.

General information

Company profile

The idea for the innovative product was born over 25 years ago. Today, Primus Line® is used worldwide as a safe, reliable and sustainable solution. It is used in the trenchless rehabilitation of pressurised pipelines (Primus Line® Rehab) and in the construction of freely layable pipelines (Primus Line® Overland Piping).
The core of the Primus Line® technology is a flexible pipe consisting of a fabric-reinforced liner and specially developed connectors. Suitable for the transport of water, oil and gas, it has the necessary approvals from many countries around the world and meets the highest standards for use in the drinking water sector.
Founded in 2001, Rädlinger primus line GmbH currently has around 100 employees at its headquarters and production site in Germany and branches in the USA, Canada, China and Australia, as well as a large, international and specially trained partner network.

Products & Services

Primus Line® technology is both strong and flexible. This is ensured by the multi-layer construction of the liner and the specially developed, leak-proof connectors.
The Primus Line pipe has a three-layer structure. The inner layer is adapted to the respective medium to be transported and is made of polyethylene (PE) or thermoplastic polyurethane (TPU) with high chemical, abrasion and corrosion resistance. The middle layer consists of a seamless woven Kevlar® fabric. It accommodates the operating pressure by itself and is up to 10 times stronger than steel of the same weight. The outer layer of polyethylene (PE) or thermoplastic polyurethane (TPU) protects the fabric from UV light and abrasion during installation and operation.
For transport the flexible pipe is coiled in U-shape on special reels and delivered to the customer. Depending on the diameter, a single reel can hold up to 4,000 metres / 13´120 feet of pipeline, which can be efficiently loaded onto a single truck.
