StrongPIPE® EXL (Extended-Life-Liner) is an economical, high-strength polyurethane lining, robotically installed. This patented lining system extends the life of existing pipelines and is an effective alternative to more invasive rehabilitation methods. It requires no excavation and can be applied at laterals and bends with no costly disruption.

The StrongPIPE® EXL system is comprised of specially formulated polyurethane layers at custom designed thicknesses.
The long-term lining system can be used on pressure pipe, gravity lines, storm sewers and culverts. It can be rapidly installed on extended runs of pipelines in diameters of 8-inches or greater. Developed to extend the life of existing pipelines, the EXL system can be designed by our application engineers to meet many life extension and pipe protection needs.

StrongPIPE® EXL Features:

  • Robotic, automated or semi-automated installation
  • Low profile system – diameter contingent, typically 1/8 to 3/4-inch maximum
  • Long-term protection for pipeline life extension
  • Well-suited for extended reaches and complex geometries
  • NSF 61 certified for drinking water pipelines
  • No excavation required, minimal downtime with access through standard manholes

StrongPIPE® MICP and EXL – SippTech™ Robotics Installation

STRUCTURAL TECHNOLOGIES, and our in-house installation licensees, provide SippTech™ Robotics installation of the StrongPIPE® MICP and EXL systems. This state-of-the-art robotics platform increases efficiency, worker safety, and installed quality of our systems.
The Robotics can fully install the StrongPIPE® MICP or EXL systems in as little as one pass, depending on the design, significantly reducing installation time. The robot train systematically installs each layer as it traverses the pipe. Lining speeds can vary between 2 to 30 feet-per-minute.
Utilizing either an umbilical control or fully autonomous supply and control systems, the system allows for unlimited lining lengths from one access point. Through computer vision, the robotic system can negotiate and line through 90-degree short radius bends, mitered bends and some valve systems.
The SippTechTM Robotics is fully equipped with an array of sensors and other proprietary equipment to provide superior quality control compared to human applied systems.
