Abstract:

This paper provides a perspective on the stress corrosion cracking (SCC) of buried pipelines based on a paper by R.N. Parkins, et al., and associated works. The paper by Parkins, et al., included an identification of factors controlling near-neutral pH SCC (NNPHSCC) and a probabilistic approach to evaluating multiple cracks. Considerable research since the publication of the paper has shed light on the mechanisms of NNPHSCC and the various contributing factors. However, a probabilistic framework advanced by this paper is still a work in progress. This perspective describes the progress that has been made and the gaps still remaining in this area.
