In cases where pipeline segments in need of repair or upgrade cannot be shut down, STRUCTURAL TECHNOLOGIES’ StrongPIPE® XPT™ External Post-Tensioning System is an effective, engineered solution.
The StrongPIPE® XPT™ External Post-Tensioning System utilizes steel tendons around the exterior circumference of an existing pipe. A StrongPIPE® XPT™ tendon consists of high-strength steel strand, coated and sheathed in extruded plastic for corrosion protection, and an anchorage assembly. The strand is looped around the host pipe and stressed at the anchorage utilizing hydraulic jacks. All of STRUCTURAL TECHNOLOGIES’ StrongPIPE® XPT™ Systems feature VSL hardware components.
The StrongPIPE® XPT™ System is highly customizable – there are a variety of anchorages and strand that may be manufactured to accommodate 42 inch diameter and above pipelines. STRUCTURAL TECHNOLOGIES assists with developing complete design, and field installation of the StrongPIPE® XPT™ System is available through our parent company’s specialty contracting partners.
