Pipe Rehabilitation
Anna Pridmore, PhD, P.E.
Vice President - Pipeline Solutions
STRUCTURAL TECHNOLOGIES’ Pipeline Solutions Engineering Team is led by Anna Pridmore, PhD. She received her doctorate in structural engineering and has over ten years of interdisciplinary experience in advanced composites, design and material science with a focus on pipeline rehabilitation.

Anna and the Pipeline Solutions Engineering Team continuously research and develop proprietary solutions that benefit our clients. The latest product in development is the StrongPIPE® Hybrid FRP System, a fully custom designed structural strengthening system for the restoration of damaged and weakened large diameter pressure pipes. Utilizing layers of continuous wound steel reinforcement layers with FRP, a composite liner is formed inside the existing pipe creating a high-value trenchless repair method.

Carbon fiber systems can be utilized to provide structural repair and upgrade for nearly any type of type of pipe including Pre-Stressed Concrete Cylinder Pipe (PCCP), Concrete, Mortar Lined Steel, Fiberglass and all types of Metallic pipelines. Since the mid-1990’s, carbon fiber reinforced polymer (CFRP) composite systems have been increasingly used for internal rehabilitation and strengthening of large diameter pipelines. The primary type of pipeline rehabilitated using CFRP is PCCP because the segmental manner in which PCCP is constructed and the localized manner in which structural...

Pipeline systems in power plants have a unique set of factors quite different from pipeline systems in municipalities. Typical municipalities have hundreds of miles of pipelines and focus on the inspection of this underground infrastructure has historically been a regular practice of the
Strengthening of pressure pipelines using carbon fiber reinforced polymer (CFRP) materials has been an accepted repair method since the late 1990’s. CFRP composites are high strength, non-corrosive and durable materials and can add considerable structural capacity which makes them very suitable for
