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.
Applications
Water
Water is a valuable resource as a basis of life, which requires sustainable use and our protection. Primus Line® guarantees a loss-free and secure conveyance of even the most-sensitive media, such as drinking water, contaminated or polluted liquids. Simultaneously, the composite pipe protects the old pipe from the inside against abrasive particles in the water and against corrosion.
Primus Line® is suitable for the transport of the following liquids in the water sector:
- potable water
- firefighting water
- industrial water
- sea water
- waste water
Gas
Gaseous media represent a special challenge to trenchless pipe rehabilitation. However, an inner layer made of permeation-reducing plastics and the seamless production of up to 4,500 metres of the Primus Liner have made it possible for gas pipelines to also be renovated with Primus Line®. A monitoring pipe with a fitted valve which is affixed to the old pipeline allows the system-specific annular space to be monitored after the renovation work. The conveyed gas covers media from categories as natural gases, liquid gases, coke gases and mixed gases
Oil
The oil industry is facing new challenges as a result of damage to steel pipelines caused by internal corrosion. Possible leakages can cause significant environmental damage; they also mean increased costs or even loss of reputation for network operators. Primus Line® is suitable for the renovation of oil pipelines due to the medium-specific inner layer, and acts as a corrosion barrier between the transported fluid and the host pipe. The conveyed fluid covers media from categories as crude oils, fuel oils, oil slag and other refined products.
Customised Products
The fields of application of Primus Line® are very diverse and will not be exhausted any time soon. The Primus Line® development team therefore works constantly in further developing the flexible relining system and creating customer-specific solutions. In close exchange with the customer, individual products are produced for special requirements.
Taking care of sensitive environments and protecting living environments
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.
Regardless of whether it involves high traffic streets, nature reserves or sites difficult to access – it is just in these cases where Primus Line® is exactly the right solution. Without any large-scale impacts on the environment, pipelines can be renovated simply, rapidly and securely and put into operation again within the shortest time. As well as economic aspects, considerable advantages therefore arise for persons and nature:
- No disturbance in the street, railway line or shipping traffic
- Avoidance of traffic jams
- Decrease of noise and emission pollution
- Decrease of excavation work
- Low level of impairment to existing building substance
- Sustainability through the use of the existing infrastructure (old piping)
- Low impact in landscapes and protection areas
- Care of plants and species
The special suitability for sensitive environments results from the special installation method of Primus Line® and its simple handling. The installation is possible in the most confined spaces and with a low level of machine employment.
