Webinar Overview
Managing the threat of corrosion intersecting a pipeline longitudinal seam weld (LSW) is a challenging task for pipeline operators. This is especially the case for operators who are tasked with adopting engineering best practices while still maintaining compliance with applicable federal regulations. Due to the current regulatory landscape regarding corrosion intersecting an LSW, pipeline operators—particularly those in the United States—are struggling to manage this threat in an effective manner.
Continued technological advancement of in-line inspection (ILI) technology has resulted in a higher instance of corrosion features reported to intersect an LSW; however, the inability of these ILI tools to reliably differentiate between selective seam weld corrosion (SSWC) and general corrosion that happens to intersect the LSW has resulted in overly burdensome response requirements. In many cases, there is sufficient justification that the elevated safety risk resulting from these excavations exceeds the risk associated with the corrosion feature itself. Regardless of the applicable regulatory environment, it is clear that the pipeline industry needs better guidance for managing this threat.
Inspectioneering teams up with Quest Integrity for our webinar, “Pipeline Seam Weld Corrosion Management.” This session will provide an overview of the current state of knowledge and industry best practices related to the assessment and management of corrosion intersecting an LSW. Topics to be discussed will include:
- Defining selective seam weld corrosion (SSWC)
- Coincident versus preferential corrosion
- Identifying and sizing SSWC via ILI and in the ditch
- Components of an effective seam weld corrosion management plan
- Navigating regulatory requirements related to seam weld corrosion
