ClockSpring|NRI introduced the industry to composite technology for pipeline and transmission line repairs and continues to raise the bar for performance. Initially, we applied our technology as a crack arrestor on high-pressure pressure CO2 lines, enriched natural gas pipelines, and other transmission lines that are susceptible to long-running cracks. Based on the success of this application, our R&D team created derivative products to extend the reach of this leading technology. Verified over a comprehensive 10-year program by the Gas Research Institute (GRI) and a team of distinguished pipeline professionals and research organizations, our solution was the first in the world to meet effectiveness, durability, and performance levels to qualify as a permanent repair.

ClockSpring|NRI has now grown its range of solutions which answer the needs of the pipeline and distribution industry with the addition of Advanced Valve Technologies EZ Valve, an inline insertion valve, and GeoTree’s range of geopolymer solutions, Geosynthetic Cementitious Composite Mats (GCCM), and structural strengthening solutions.
ClockSpring|NRI set the standard for excellence and today offers the industry’s most complete suite of repair solutions for restoring and maintaining active pipelines, enabling safe, reliable operations in compliance with state and federal regulations.
