Thermo-Wrap™ is a custom engineered composite system utilizing a high strength, non-crimped bi-directional fiberglass architecture in conjunction with NRI’s patented inspectable Thermo-Poxy™ epoxy system to repair corroded or damaged piping. Using common radiographic inspection methods, owners and operators have the ability to monitor the integrity of an “in-service” Thermo-Wrap repair through the course of its intended design life. It is a qualified, engineered system designed to conform to ASME PCC-2, ASME B31, ISO TS24817, DOT, API, and CSA Z662 standards for nonmetallic reinforcing solutions.
