Trans-Wrap™ is a bidirectional non-woven 100% carbon fiber composite, saturated with NRI’s proprietary epoxy system, Thermo-Poxy™. The Trans-Wrap carbon fiber is oriented in the 0˚ / 90˚ directions and is stitched resulting in outstanding tensile values in both directions. It has a high thickness per layer resulting in fewer layers needed for reinforcement and quicker applications. The Thermo-Poxy Epoxy system is a two-part, 100% solid epoxy designed for use in a wide variety of environments possessing excellent chemical resistance and high temperature ratings.

Additional information

Surface preparation:

Surface preparation and profiling shall promote continuous intimate contact between the CFRP system and pipe by providing a clean, smooth, and circumferential surface. Surface preparation shall be in accordance with SSPC-SP1 “Solvent Cleaning” and SSPC-SP10 / NACE 2 “Near White Blast Cleaning” 1-3 mil surface roughness (25-75 microns). If an exist-ing coating is present, roughen to degloss. The composite repair system is a bond -critical composite repair system requiring a strong adhesive bond between the clean pipe and the composite system.

Installation:

Installation of the composite System shall be performed by NRI qualified applicators only. Surface preparation, mixing of epoxy, and installation of the system are to be in accordance with NRI’s composite Installation Guide, latest revision. Quality control inspection during and after installation of the composite system shall be performed per NRI’s Installation Validation Procedure: Quality Control Records, latest revision.

Storage conditions:

Store in a cool, shaded area at an ambient temperature of 35ºC.
