Development of Non-Destructive In-Service Detection of Damage Severity for Pipeline Steel Inspection

The objective of this project is to develop an advanced technique based on residual stress to evaluate the damage severity through the coating on coated steels, as regulated by Pipeline Safety Regulations 49 CFR Parts 190- 195. This will enable improved integrity assessment and reduce the number of unnecessary pipeline removal and replacement activities. The anticipated Phase I results will include the use of a residual stress mapping technique to analyze residual stress around pipe dents and wrinkles and will provide the foundation for Phase II activities to produce a calibration system that enables accurate measurement of residual stress in a variety of pipeline damage types. The ability to quantitatively measure residual stress is widely desired and the proposed tool should be useful in many areas. Potential commercial applications include assessment of onshore and offshore pipelines, risers, piping and tubing, and pressure vessels, as well as machining of a wide range of industrial, military, and government components (e.g. telescope lenses and missile nosecones).
