StrongPIPE® SCL

StrongPIPE® SCL System

In response to pipeline applications involving repair or renewal of extended runs of large diameter pipelines using trenchless methods, STRUCTURAL TECHNOLOGIES created the StrongPIPE® SCL system. This unique composite system is made up of layers of reinforcing steel wire and fiber-reinforced polymer to provide fully structural repairs and upgrades to pipe segments. The StrongPIPE® SCL system is applicable to all types of pipelines and is installed internally starting at pipe diameters of 42 inches and above.

StrongPIPE® SCL is a proprietary solution which combines the benefits of steel reinforcement with FRP to create a high-value trenchless repair system for large diameter pipe. Custom designed for each application, StrongPIPE® SCL combines layers of reinforcing steel and FRP to create a fully structural strengthening system for renewal or restoration of damaged/weakened large-diameter concrete or metallic pipelines. StrongPIPE® SCL utilizes a continuously wound steel reinforcement that with the FRP forms a composite liner inside the existing pipe.

 

Composite System Features

  • Fully structural repair system – custom designed to address all internal pressure and external loads
  • Lower installed cost compared to other rehabilitation alternatives
  • Low profile system (typically 3/8-inch to 1-inch)
  • Long term lifecycle extension of pipeline assets
  • Extended reaches or segmental repairs of pipe
  • Restores full functional capacity of distressed, degraded or damaged pipelines
  • Upgrade the structural capacity of an existing pipe allowing increased operating pressure
  • No excavation needed – access through standard manholes
  • NSF 61 and Annex G certified for drinking water pipelines
  • Minimal downtime and impact to operations
