Breakthrough Technology – NRI’s Inspectable Thermo-Wrap™ Composite System

Thermo-Wrap™ is a custom engineered composite repair system that utilizes high-strength, noncrimped bidirectional fiberglass architecture in conjunction with NRI’s new, patent pending Inspectable Thermo-Poxy™ epoxy system. Thermo-Wrap is used to repair corroded or damaged refinery process piping with harsh chemical services and elevated temperatures. Thermo-wrap is an operator-qualified, engineered system designed to conform to ASME PCC-2, ASME B31, ISO TS24817, DOT, API and CSA Z662 standards for nonmetallic reinforcing solutions. Using common radiographic inspection methods, owners and operators now have the ability to monitor the integrity of an in-service Thermo-Wrap repair through the course of its intended design life. This allows for full quality control procedures to be completed through all phases of the composite repair’s service life including:

  • Validation of the repair thickness per NRI Design Calculations.
  • Enhanced monitoring to know what is happening within the composite system at each layer and at the critical bond interface enabling better risk management analysis.
  • Location internal defects in the steel substrate under the composite repair system without performing destructive ing to the composite reinforcement system.
  • Full visibility through the host pipe and through each individual composite layer to monitor the structural integrity of the system as a whole.
  • Identification of air voids, foreign objects and liquids within the composite reinforcement system.
  • Monitoring of corrosion rates.
  • Extend design life of composite repair.

The objective of NRI’s patent pending inspectable composite system is to maximize the safety and reliability of existing NRI composite repair through a preventive maintenance (PM) program. This allows owners and operators to validate the repair is in compliance with the design requirements of the piping system and related specifications required by NRI. Properly conducted PM inspections will result in an accurate assessment of NRI’s composite repair condition and the rate at which that condition may or may not be deteriorating.

Thermo-Wrap Composite Wrap for Pipelines

PM of nonmetallic composite repairs requires ongoing data collection through scheduled inspections. Inspection should be combined with an NRI Engineer evaluation of the findings. Documentation of the inspection can be used for trend evaluation during the repairs design life.

In conclusion, the ability to now validate the integrity of NRI’s composite repair system will provide end users with a safer working environment by having the ability to now establish a risk management process at all phases of a composite repair’s service life. For more than 30 years, NRI has been an industry leader in research and development, engineering design and manufacturing of pre-impregnated and field saturated composite strengthening systems that restore, protect and reinforce pipes, pipelines and civil structures. Today, NRI’s dedicated team of engineers is on the cutting edge of research and development, formulating, ing and designing tomorrow’s new product breakthroughs in quality composites.
