Thermo-Wrap™ Composite Repair System for High Temperature and Process Piping
PRODUCT INFORMATION
Thermo-Wrap™ is a custom engineered composite system utilizing a high strength, bidirectional, woven fiberglass tape in conjunction with NRI's proprietary Thermo-Poxy™ epoxy system for the repair and restoration of pipes operating at elevated temperatures. This operator qualified engineered system was designed to conform to and recognized by ASME PCC-2, ASME B31, ISO TS24817, DOT, API, and CSA Z662 standards for nonmetallic reinforcing solutions, thus ensuring product application integrity. Thermo-Wrap is specifically designed for repair applications which require the composite to maintain the high design strengths in high temperature environments, while still curing under room temperature conditions.

THE RESINATOR INSTRUCTIONS
- Place Resinator on stable flat surface.
- Remove black knobs from ends and fold up arms. Replace and tighten knobs to secure arms in upright position.
- Position impregnating box into frame, fitting down securely. Black scraper blade should be at side closest to the winding handle.
- Push up on feeder axle to remove and slide on plastic core with cloth, aligning key inside core with groove on axle. The core will keep the cloth centered for precise feeding into the impregnating box. Snap axle with cloth back into place.
- Snap out take up axle with handle. Place empty core on to take up axle. Snap take up axle back into place.

- Remove tape securing cloth on to roll and thread under guide rods and up through opening in scraper bar. Draw enough cloth through to wrap around take up core.

- Mix resin and pour into impregnating box filling to just BELOW opening in scraper bar.


- Replace lid aligning cut out ends with cloth.
- Slide in two holding rods and tighten to place securing the lid and holding the box in position during operation.
- Turn handle on take up axle at moderate speed to allow full impregnation of cloth.

- Remove holding rods and top to add more resin as needed, replace and continue. Impregnation should always be done with top on to prevent contamination of resin.
- Use wide piece of duct tape to connect next roll of cloth before end of roll enters box. This will thread next roll of cloth under bars and into scraper.
- Replace box when resin begins to get firm ( set )
