Stress corrosion cracking of oil and gas pipelines in near-neutral pH environment: A review of recent research results

Since the first discovery of transgranular stress corrosion cracking (SCC) on a Canadian gas transmission line in 1985, a great deal of research has been conducted in the past 20 years. Findings of the effects of operating conditions, metallurgical factors and the soil environment have been very useful in preventing and mitigating uncontrolled failures. Several overview summaries of the progresses in this area can be found in the open literature and this review is an effort to update the research results on this subject matter produced in the past five to six years.
