Trenchless Rehabilitation
Pipeline Rehabilitation Made EasyPrimus Line Rehab is an innovative technology for the trenchless rehabilitation of pressure pipelines for different media such as gas and oil. This technology offers a safe, reliable, and sustainable solution for trenchless rehabilitation of pressure pipes. The process is based on a flexible high-pressure liner and a connection technology developed specifically for this system. The Primus Line Flexible Rehab Pipe is suitable for the transportation of various liquids and even has drinking water approval in many countries. The ideal flow characteristics due to a smooth inner coating and the optimized systems for high, medium and low-pressure requirements make Primus Line Rehab an economical solution for the rehabilitation of aging pipelines. Network operators benefit from reliable operation and a sustainable investment in their assets. |

Fast and Easy Deployment
Suits Most EnvironmentsPipelines often run through environments that are hard to access. Obstacles to an easy and fast rehabilitation of aging pipes can be of geographical, economical, architectural or environmental nature. Installation only requires small excavation pits at the beginning and end of the section to be rehabilitated. Existing manholes can also be used. This speeds up the work, protects the environment, and significantly reduces the CO2 footprint. |
Suitability of Primus LinePrimus Line is suitable for a quick and reliable rehabilitation of pressure pipes between DN 150 and DN 500 (6 inches to 20 inches). Several bends can be traversed while achieving installation lengths of up to 2,500m / 8,200 feet. |

Performance
Reliable and VersatileOur oil and gas pipe rehab stands for the fast and reliable rehabilitation of pressure pipelines. Several bends can be traversed, and installation lengths of up to 8,200 feet can be implemented with only a small amount of machinery. This makes the system ideal for use in environments with high geographical, economic, architectural, or ecological requirements. Cost Advantage

Sizes & Transport
This system is available in sizes DN 150 to DN 500.
The flexible pipe is coiled in a U-shape onto specialized transport reels and delivered to the customer. Depending on its diameter, a single reel can accommodate up to 4,000 metres / 13,120 feet of pipeline, efficiently fitting onto a single truck. This approach minimizes both logistics costs and the environmental impact associated with transport.
