Transitioning from Leak Detection to Leak Prevention: Proactive Repair of Steel Pipelines Using Fiber Reinforced Polymer (FRP) Composites
Steel pipelines are the one of the most economic and safe transport systems for water, and are often our population centers' only means of receiving goods which are vital to day-to-day existence. As a means of long-distance transport, pipelines have to fulfill high demands of safety, and reliability. Most metallic pipelines, regardless of what they transport, are designed with a typical life span of 25 – 50 years. When they begin to fail, the pipelines slowly form leaks at construction joints, corroded areas and small structural cracks. These leaks can gradually progress to a catastrophic failure if gone undetected or can result in substantial water loss over extended periods of time. Pipeline leak detection systems (LDS) are beneficial because they can enhance productivity and system reliability by means of reduced downtime and reduced inspection time through pinpointing and localizing the leak locations. LDS Systems are therefore an important aspect of pipeline technology that are primarily used to assist Pipeline Owners in detecting leaks. But what happens after leaks have been detected in steel pipelines and require immediate repair? This paper will present the importance of the correlation between efficient leak detection and pipeline repair. The general guidelines for the proper design and installation of fiber wrap strengthening systems for steel pipelines will also be presented. Discussion will center upon case histories and best practices to avoid over or under-designing the retrofit, and how to best implement the proper installation of these CFRP systems. The case studies will be explored in detail to evaluate the performance of past and present designs, both for municipal and industrial clients.
