Natural Gas Distribution

When shutdown is not an option, NRI’s Engineered Composite Repairs (ECR) systems offer a permanent, cost-effective repair to natural gas pipelines. Whether it is an active leak or external corrosion, NRI’s Trident family of products are a superior alternative, both in performance and value over traditional repair go-to options such as steel sleeves or complete pipeline replacement of the affected area. NRI’s Trident products are simple and quick to apply without service interruptions, costly additional labor and the long-drawn-out repair process associated with outdated, traditional methods.
