Corrosion Chronicles – Details, episodes & analysis

In this episode, Steve Springer, a materials engineer at Chemours Engineering, joins co-hosts Heather Allain and Marc Cook to discuss the critical role of flexible hoses in chemical facilities. They cover a range of topics, including a tragic incident that resulted in a fatality, the importance of having a robust hose program, and key considerations in hose design and construction. The conversation also touches on appropriate and inappropriate uses, corrosion allowance, inspection protocols, full penetration welds for end connections, pressure and vacuum ratings, and best practices for installation.

In our season 2 premier, Ed Naylor, Senior Materials Engineering Associate at Nouryon, sits down with co-hosts Heather Allain and Marc Cook to discuss storm damage in the context of chemical facilities. They explore how to identify site-specific vulnerabilities, the unique hazards hurricanes pose, and essential preparation steps before storm season. The discussion also covers the role of hazard response teams, the cascading effects of storm damage, post-storm assessments, and the material degradation mechanisms to anticipate.
