PR-186-224500-R01 Assessment of Non-Welded Pipeline Repair Methods to Reduce Pipeline Blowdowns
Abstract
Non-welded repairs, such as fiber-reinforced composite systems and clamps with elastomer seals, may degrade over the life of the pipeline. As pipelines get older, it is important to evaluate the available repair options, and those currently installed, for continued service. This project explored the degradation associated with these non-welded repairs and provides practical guidance on how to assess, limit, or extend their service life. This will facilitate a reduction in Greenhouse Gas (GHG) emissions from a potential leak of a non-welded/temporary repair, allowing operators to either plan for their replacement with a permanent in-service repair or justify their continued use without arbitrary replacement.
This research was a recommended next step following PRCI Project MATR-3-15, Methods to Reduce Pipeline Blowdowns to Effectuate Repairs and Inspections. It is a precursor to MATR-3-15B, which is expected to conclude in 2025.
