Process Piping

The mechanical integrity of process piping is critical to effectively manage process safety, environmental hazards, and business risks in the oil & gas, chemical, petrochemical and power industries. A process piping system failure or leakage could have a significant impact on the business due to interruptions in production, or a catastrophic effect if an explosion or fire occurs or a hazardous fluid is released. Unique geometries often found at such facilities present significant challenges in repairing and maintaining integrity strategy for piping. These challenges are compounded by piping and process complexities, misunderstandings and underestimating the importance of piping. NRI offers a line of emergency leak and structural repair products that address all of the challenges and  help you stay in compliance with state and federal regulations.

Engineered Composite Repairs (ECR)

Engineered composite repairs (ECR) are used to repair and reinforce internal or external corrosion on chemical, oil, gasses, water and steam piping. NRI offers multiple solutions that not only repair the pipe but put it back in service stronger than when it was brand new. They are conformable for repairing straights, elbows, tees, nozzles, reducers, welds and headers. All products are designed to conform to ASME PCC-2, ASME B31, ISO 24817, DOT, API, and CSA Z662 standards. There is no heating or post-curing required. All solutions are cost-effective.
