The Steel-Wrap™ E composite repair system is comprised of a unique, uni-directional carbon fiber fabric, saturated with Steel-Wrap Epoxy, and primer system.


InformationTesting Data

Typical Applications

  • Deficiencies including dents, gouges, wrinkle bends, and cracks
  • Deterioration and damage including CUI, metal loss, pitting, cracking
  • Regulatory changes including classification factor changes, road crossing reinforcement, casing alternative
  • Structural steel applications including steel member reinforcement; steel plate repair for tanks, decks, hulls; stiffening/load capacity increase; weight reduction


  • Stiffer and stronger than steel
  • No post-curing necessary
  • Stronger physical properties than steel = lower design thickness
  • Highest strain reduction available

Pot Life

  • Filler: 25 minutes @ 75°F (24°C), less at higher temperatures
  • Primer: 15 minutes @ 75°F (24°C), less at higher temperatures


  • Epoxy application temperature: minimum of 50°F (10°C) and maximum of 110°F (43°C)

InstallationInstallation of the Steel-Wrap E System shall be performed by NRI trained installers only. Surface preparation, mixing of epoxy, material saturation, and installation of the system are to be in accordance with NRI’s Steel-Wrap E Installation Guide, latest revision. Quality control inspection during and after installation of the Steel-Wrap E system shall be performed per NRI’s Installation Validation Procedure: Quality Control Records, latest revision.

The Steel-Wrap E 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.

Shelf Life

    12 months with proper storage

Cleanup and SafetyIn case of spillage, absorb and dispose of in accordance with local applicable regulations. Read and follow all caution statements on this product data sheet and on the SDS for this product. Wear protective clothing and gloves, and use protective cream on face, hands, and all exposed areas. When used in enclosed areas, thorough air circulation must be used during and after application until the coating is cured. User should test and monitor exposure levels to ensure all personnel are below guidelines.
