Large Diameter Pipes
We specialize in repair and retrofit of large diameter pipes and PCCP with carbon and glass FRP and have won international awards for such projects. We hold the record for having repaired the world's largest pipeline with FRP -- 1.1 mile of an 84-inch pipe in the mountainous terrains of Costa Rica in a record 15 days.
Small Diameter Pipes
Some of our PipeMedic™ laminates are so flexible that they can be used to repair pipes as small as 3 inches in diameter. Even these flexible laminates have tensile strength of 60,000 psi, which is considerably stronger than mild steel. Installation can be performed with packer devices as shown here.
Pressure Pipes for Gas Industry
PipeMedic™ is the only FRP product that has been tested by the Gas Technology Institute and has been approved for repair of pressurized natural gas pipelines. The thin laminates can be remotely installed, allowing the pipe to resist internal pressures in excess of 250 psi.
StifPipe™: Honeycomb Sandwich Tech
StifPipe™ is another patent-pending technology we have developed for repair of pipes and culverts. StifPipe™ is a per-manufactured pipe that can be constructed to any size and shape. Unlike conventional pipes, the walls of this pipe are made of a lightweight honeycomb core. StifPipe™ is ideal for projects where the liner must be capable of resisting considerable gravity load from traffic and soil pressure.
