ThermoWrap 500

Composite repair system for extreme temperatures in process piping.

Thermo-Wrap™500 is a factory-saturated, custom engineered composite repair system compatible with temperatures reaching 500°F (260°C). NRI’s patented factory-saturation process ensures the right fiber-to-resin content ratios are achieved. By eliminating the need for field saturation, this product can be applied faster and more efficiently on pipes with elevated operating and design temperatures. Thermo-Wrap™ 500 has been tested in accordance with ASME PCC-2 Article 4.1.
