Thermo-Wrap™500

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 fieldsaturation, 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.

Design

The Thermo-Wrap composite repair system was designed to conform to, and is recognized by ASME PCC-2, ASME B31, ISO TS24817, DOT, API, and CSA Z662 standards for nonmetallic reinforcing solutions. Consult NRI Engineering for specified use.

Surface Preparation

Surface preparation and profiling shall promote continuous intimate contact between the FRP system and pipe by providing a clean, smooth, and circumferential surface. Surface preparation shall be in accordance with SSPC-SP1 “Solvent Cleaning” and SSPC-SP11 “Power Tool Cleaning” with a 1-3 mil surface roughness (25-76 microns) minimum. NRI’s composite repair systems are bond-critical and require a strong adhesive bond between the clean pipe and the composite system for maximum effectiveness.

Installation

Installation of the Thermo-Wrap Inspectable composite repair system shall be performed by NRI qualified applicators only. Surface preparation, mixing of epoxy, material saturation, and installation of the system shall be in accordance with NRI’s product specific installation guides, latest revision. Quality control inspection during and after installation of the system shall be performed per NRI’s Installation Validation Procedure: Quality Control Records, latest revision.

Cleanup and Safety

For proper information regarding the safe handling, storage, and disposal of chemical products, users shall refer to the most recent SDS, latest revision, containing physical, ecological, toxicological, and other safety-related data.
