    ViperSkin™ is the first bi-axial, hybrid carbon and glass fiber, pre-saturated system to blend the unsurpassed strength and stillness of carbon with the ease and use of a moisture-cured, factory-saturated polyurethane. The pre-saturated system ensures appropriate fiber-to-resin content ratios to deliver reliable performance in restoring pipeline integrity on lines with complex geometry.

    Feature  Benefit
    Moisture-cured polyurethane resin Factory saturation of moisture-cured polyurethane resin reduces composite field preparation time by more than 50%
    Factory-saturated fiber Factory saturation ensures the right fiber-to resin ratio with constant strength and mechanical properties
    Full engineering consultation and support Easy application in any conditions, including damp or sweating pipes and in submerged environments
    Non-shielding No heating or post-curing steps necessary
    Can be applied to any geometry including, but not limited to elbows, tees, and flanges Suitable for irregular shapes and geometries
    Conforming Standards: ASME PCC-2, ASME B31, ISO 24817, DOT, API, and CSA Z662 standards for nonmetallic reinforcing solutions Can be used on lines (pipes) of any diameter

    Standards

    Viper-Skin was designed to conform to 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 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 existing coating is present, roughen to degloss. The Viper-Skin composite repair system is a bond-critical composite repair system requiring a strong adhesive bond between the clean pipe and the Viper-Skin system.
