Weld Flaw Acceptance Criteria for New Pipelines – 21 June 2022

16 May 2022 1:12 PM | Anonymous

We are excited to invite you to attend our upcoming Structural Integrity Technical Group webinar titled, ‘Weld Flaw Acceptance Criteria for New Pipelines,’ on the 21 June 2022, 2:00 PM - 6:00 PM (UK Time).


Attendees will learn about the implementation of fracture mechanics methods, (Engineering Critical Assessment = ECA), to derive flaw acceptance criteria for pipeline girth welds. In particular, overviews of the main standards applied for this purpose will be discussed, e.g. CSA Z662, API 1104 and DNV-OS-F101/RP-F108. Challenges introduced with the use of ECA will be discussed and the event will be rounded off with presentations on fatigue assessment for offshore risers and future challenges for the use of ECA on pipelines.

This webinar is aimed at materials, welding and NDT engineers, fracture mechanics specialists, pipeline engineers and all others who are interested in pipeline integrity, especially those involved in pipeline construction whether it is onshore or offshore.
