Autonomous Rehabilitation and Maintenance of Natural Gas Pipes
Project Innovation + Advantages:
Autonomic Materials, Inc. (AMI) proposes a new category of rehabilitation materials for legacy naturalgas pipes. The novel Extruded-in-Place Pipe-in-Pipe (ExiPiPTM) rehabilitation solution for legacy gas piping avoids costly excavation-intense replacement while providing a new structurally independent pipe offering a 50-year life span. This solution leverages frontally cured poly(dicyclopentadiene) as the new pipe material and will feature self-healing and self-reporting functionalities. This material will be deployed in a live pipe and supported by a modular robotic platform capable of incorporating pre- and post-inspection payloads as well as a deposition tool for extruding and curing the new pipe material. Data acquired in pre-, post-, and maintenance inspections will provide valuable information for more effective integrity management of the new pipe. At a projected cost of less than $1 million per mile, ExiPiPTM significantly decreases legacy pipe rehabilitation expenses.
REPAIR seeks to eliminate the highest pipe rehabilitation costs, excavation and restoration, by repairing pipes without their removal.
