pressure pipe

The Thermopipe® system is a non-disruptive, close-fit pressure pipe rehabilitation system. Thermopipe® is a high tenacity polyester reinforced liner ideally suited for the rehabilitation of potable/non-potable water mains and other pressurized piping systems of up to 12-inches in diameter.

Supplied as a factory-folded “C” shape liner, the Thermopipe® liner is winched into the host pipe from a reel and inflated with air. Once inflated, 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.

  • Diameter ranges from 4 to 12 inches
  • Independent fully structural internal pressure design rating of 200 psi
  • Stops leakage by bridging and sealing holes and faulty joints
  • Rapid installation – up to 1,000 LF in just a few hours
  • In approval process for drinking water applications
  • Minimizes disruption
