Research seeks more precise corrosion defect assessment; Part 1
- Battelle, Columbus, OH (United States)
Heightened competition among energy suppliers is making cost-effective maintenance and rehabilitation decisions increasingly important. Accepted methods for evaluating corroded pipe's remaining strength, while sound and well validated, are semi-empirical and limited to specific corrosion defect classes. Key industry concerns on the effects of axial loads on defect behavior and on interaction of adjacent defects cannot adequately be addressed by the classical acceptance criteria such as ASME B31G. The industry, through the Pipeline Research committee (PRC) of AGA and the Gas Research institute (GRI), has recognized the need for improved understanding and behavior models of corroded areas in pipelines. Under PRC sponsorship, Battelle is conducting research to develop engineering guidelines for evaluating corrosion defects, including axial load effects and defect interaction. GRI is funding research on use of a composite sleeve to more cost-effectively reinforce pipe line corrosion defects.
