ECC is pleased to introduce this Guidance for Managing Near Neutral pH Stress Corrosion Cracking, which is a companion document to the guideline CEPA produced in 2015. Both SCC guidance documents will be referenced in the upcoming revision of CSA Z662.
This guidance comprises nine steps encompassing three main aspects: susceptibility assessment; condition assessment and mitigation; and condition monitoring. This guidance, with an expanded section on circumferential SCC, reflects updated research and practices by the pipeline industry in general and by member companies in particular for the management of near-neutral pH SCC on their gas and liquid pipeline systems. Some practices are common among operators; others differ. The dynamic nature of this threat necessitates active monitoring and as-needed changes in practices by each operator when and where warranted.
This revised SCC Guidance was developed via an ECC committee including colleagues at:
-
Gibson Energy Inc.
-
Husky Midstream
-
Pembina Pipeline Corporation
-
Plains Midstream Canada ULC
-
TC Energy Corporation
-
Trans Mountain Corporation
We also recognize Dynamic Risk Assessment Systems, Inc. for leading the update. We thank all involved for their dedication to this project.
