Data and Report from S&T Project 20074: Leak Repair Demonstrations for Pressurized Mechanical Systems

This work investigated composite repairs for leaking pressurized mechanical systems, seeking to gain quantitative data on the effectiveness and estimated lifetime of various repair systems. Laboratory testing showed that the five repair systems tested are only effective on very minor, weeping leaks and only for short periods of time. Information provided by field partners supports that there is an existing need for leak repair options on mechanical systems that are unable to be depressurized. For lower pressure leaks (less than 20 psig), field partners have successfully used fiberglass wraps, as well as non-composite repairs such as patches and clamps. For higher pressure (more than 20 psig) leaks, field partners have not found repair options that can be applied without first isolating the leak, which in many cases, is not possible. With much of the infrastructure at the field partner facilities nearing or passing its design life, it becomes increasingly important to find solutions that can address leaks, corrosion, and other degradation, either temporarily until the system can be isolated or permanently, if possible.
