Project Scope
• Rehabilitation of 440LF of 12‐inch Asbestos Cement Pipe (ACP)
• Heavy traffic and utility corridor
• Pipe depth of up to 35 feet due to pedestrian tunnel above pipe
• Multiple bends up to 45‐degrees
• Impossible to open cut/ remove & replace
• Jack and bore was priced out – Primus Line reduced budget by 60%
Material Selection
• Primus Line – Polyethylene lined and coated Kevlar
– 3 design / pressure ratings
– 6‐inch to 20‐inch pipelines with at least 15psi
– Both potable and nonpotable systems
Construction Details
• Portals installed in turn lanes and center dividers
• Portals were 12’ x 8’ (2 total)
• Traffic was maintained through busy roundabout
Pipeline Preparation
• Sharp edges must be removed prior to liner installation
• ACP did not require any surface preparation
• Cast iron bends had severe tuberculation
– Vactor pressure nozzle used for initial preparation
– Soft pipe pigs pulled through
Liner Installation
• Liner is folded and taped at factory and shipped on cable reel
• 10k ton wench used to pull liner
• 30 minutes of pulling, only 2k ton of force needed
• 15psi of air pressure to break tape loose inside pipe
• No bonding to host pipe
Termination of Liner
• Epoxy coated carbon steel or stainless steel flanged fittings
• Connects to host pipe with flanged coupling adaptor
• Primus Line flanged fitting is a compression fitting on liner
• 3 hours to install fittings at each portal location
Startup and Testing
• 200psi pressure test for 2 hours
• Disinfected using slug chlorine method
• Both passed on initial tests
Project Summary
• Installation of 440lf of 12‐inch Primus Line
• Rehabilitation of potable water pressure pipe with 200psi rating and 5 bends in host pipe alignment
• Project completed for 60% less than dig and replace (w/ jack and bore)
• Installation by J. Wise Construction using JOC contract
