High Temperature Hydrogen Attack

About this episode

Nate Sutton discusses high-temperature hydrogen attack and its risk evaluation and mitigation strategies.

In this episode, Nate Sutton, materials engineer at Equity Engineering, joins co-hosts Heather Allain and Marc Cook for a deep dive into high-temperature hydrogen attack (HTHA) and the evolving guidance used to evaluate and mitigate its risks. Nate shares his firsthand insights on the origins and evolution of Nelson curves, the role of post-weld heat treatment, and the recent development of time-dependent curves still under review by API. The discussion also explores the role of advanced non-destructive examination (NDE) techniques, MTI’s contributions to HTHA detection and assessment, and how fitness-for-service decisions are made under high-stakes conditions. This episode is sponsored by Tricor Metals and Webco Industries. Corrosion Chronicles is produced by Association Briefings.
