Primus Line Rehab - Pressure Pipes Trenchless Rehabilitation

Safety

• Core made of seamlessly woven Kevlar® fabric. This synthetic fibre is up to ten times stronger than steel
• The burst pressure of the flexible pipe is at least 2.5 times the allowable working pressure
• No work with hazardous materials on site
• Continuously monitored production process

Cost advantage

• Installation speeds of up to 10 metres per minute
• Up to 2,500 metres per pull
• Short downtimes thanks to quick recommissioning
• Low pre-investment for installation companies
• Service life of more than 50 years

Efficiency

• Installation through multiple bends up to 90 degrees
• Withstands thermal expansion of the host pipe and ground movement
• Burst pressure rates up to 206 bar
• Operating pressure up to 82 bar
• Independet of host pipe
• No curing, steaming, adhesion or thermal treatment of the liner after installation required
• Almost independent of weather conditions during installation

Environmentally orientated

• Minimum use of machinery: This can result in a significant reduction of the carbon footprint
• Installation via small excavation pits, chambers and structures
• Decreased impact on traffic
• Only small construction site areas required
• Reduction of the on-site carbon footprint by up to 90 per cent compared to dig and lay
• We also pay attention to sustainability as a company
   
   

Primus Line® is installed trenchlessly. This means: No more excavation pits with a length of several hundred metres of even several kilometres.

Two pits or existing shafts are sufficient for rehabilitating pressure pipelines. To complete the installation, just a few steps are necessary:

Preparation

• Creating the access
• Decommissioning the pipeline
• Inspecting the host pipe
• Cleaning the host pipe

Installation

• Inserting the liner
• Mounting the connectors
• Pressure test

Reintegrating the rehabilitated pipeline

• Installing a fitting piece
• Comprehensive documentation
