Main Objective
Determine the effectiveness of bonded composite repairs for the repair of corrosion defects that are, or will become, through-wall during the repair lifetime.
Public Abstract
This project will investigate the effectiveness of patch-style bonded composite repairs of through-wall corrosion defects. Composite repairs of pipeline and pressure equipment are a growing segment of the corrosion mitigation industry and have seen large expansions since the introduction of the technique in the early 1990's. Industry acceptance has widened since the initial products came on to the market and the capabilities of these repairs have steadily increased as companies and universities have initiated research and development programs.
This research program will expand an existing PHMSA-funded research project by increasing the scope to include through-wall defects. A dedicated graduate student will investigate the performance of patch repairs under pressure fatigue loading. We expect that this project will give new insight into the performance of bonded composite repairs and will lead to revisions in the current design standards. This is a collaborative project between the research team and industry partners that have committed time and materials to this research program.
