Pipe Rehabilitation - Extending the Life of Critical Pipelines

Damaged pipeThe reliability of critical water systems is an ongoing concern for public agencies, industrial, and power generation owners and their consultants. Owners with 30-inch and larger pipeline assets have a number of options available for the repair and strengthening of distressed segments, or for the proactive renewal of extended runs of pipe. Based on the level of deterioration - our engineered products are custom designed to help owners significantly extend the life cycle of their critical pipelines.

STRUCTURAL TECHNOLOGIES provides strengthening systems for restoration of damaged and/or weakened pressure pipelines and pre-stressed concrete cylinder pipes (PCCP), as well as the proactive renewal of critical pipeline segments. Our repair options include state-of-the-art materials which provide engineered value through short construction windows and little to no disruption to operations and traffic patterns.

Through the use of advanced technologies - such as carbon fiber reinforced polymer (CFRP) strengthening systems for internal buried pipe repair and post-tensioning for external open trench repair - STRUCTURAL TECHNOLOGIES provides clients with a wide range of proven product solutions which repair and extend the life of vital pipeline assets.

    Whether strengthening from inside or out, buried or excavated, STRUCTURAL TECHNOLOGIES has answers for your pipe rehabilitation needs:

    StrongPIPE® Hybrid FRP

    StrongPIPE® Hybrid FRP

    In response to pipeline applications involving renewal of extended runs of large diameter pipelines using trenchless methods, STRUCTURAL TECHNOLOGIES created the StrongPIPE® Hybrid FRP system. This unique composite system is made up of layers of reinforcing steel wire and FRP to provide fully structural repairs and upgrades to pipe segments. The StrongPIPE® system is applicable to all types of pipelines and is installed internally starting at pipe diameters of 36 inches and larger.

    StrongPIPE® Hybrid FRP 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® combines layers of reinforcing steel and FRP to create a fully structural strengthening system for restoration of damaged/weakened large diameter pressure pipe. StrongPIPE® Hybrid FRP utilizes a continuously wound steel reinforcement that forms a composite liner inside the existing pipe.

    StrongPIPE™ Hybrid FRP Systmes for Pipe
    Benefits
    • Lower installed costs compared to alternatives (FRP, steel slip lining, partial or full pipe replacement)
    • Localized repairs or extended reaches of pipe
    • No shafts or excavation required to perform repairs
    • Access through standard manholes
    • Minimal downtime and impact to operations
     

    V-Wrap™ Carbon Fiber System

    V-Wrap™ Carbon Fiber System

    V-Wrap™ is a structural strengthening system for the restoration of damaged/weakened pressure pipe. It utilizes layers of specially designed carbon fiber reinforced polymer composite applied both longitudinally and circumferentially.

    Carbon fiber design and number of layers are a function of the exact design requirements. The existing piping system becomes a form for the V-Wrap™ CFRP system which becomes the pipe once the system is installed.

    • Corrosion resistance provides long service life
    • Fits both straight and curved pipe sections
    • No excavation required to install system
    • Excellent for localized repairs
    • Minimal downtime and impact to operations
    • Polymer coating improves flow
     

    XPT™ Post-Tensioning System

    XPT™ Post-Tensioning System

    The XPT™ Post-Tensioning system is an engineered solution utilizing reinforcing wire installed circumferentially at the exterior of designated pipe segment(s). The XPT™ System is fully structural and provides strengthening to weakened or distressed pipelines or can be used to proactively renew exposed pipelines.
