A Structural, Close-Fit Pressure Pipe Rehabilitation System
Thermopipe® is a thin, reinforced polyethylene liner ideally suited for the rehabilitation of distribution water mains and other pressurized piping systems up to 12-inches in diameter.
Supplied as a factory-folded “C” shape liner, the Thermopipe® polyethylene liner is winched into the host pipe from a reel and reverted with air and steam. Once inflated and heated, the liner forms a close-fit within the host pipe, creating a jointless, leak-free lining system able to independently carry the full system internal design pressure. The installation process is simple and can usually be completed within an 8-hour time period.
Benefits
- The polyethylene liner stops leakage by bridging and sealing holes and faulty joints
- Improves quality of water within the water main
- Reduces the social cost of water main repair because of the minimal jobsite footprint and minimal downtime
- Extends life of water infrastructure with a 50-year design life
Technical capabilities:
- Independent structural lining with internal pressure rating of 170 psi (230 psi for 4 inch through 8 inch)
- Diameter ranges from 2.75 inches to 12 inches
- Rapid installation: up to 1,000 linear feet in just a few hours
- Negotiates multiple bends
In addition to potable water distribution mains, Thermopipe® may be suitable for:
- Sewer force mains
- Fire water mains
- Industrial pressure applications
Approvals:
- Thermopipe® polyethylene liner is certified by NSF International as complying with the requirements of NSF/ANSI Standard 61
- Manufactured under a Quality Management System that is certified to the ISO 9000:2008 standard
