Corrosion Chronicles

In this episode, Ana Benz, Chief Engineer at IRISNDT, joins co-hosts Heather Allain and Marc Cook for a deep dive into selecting non-destructive examination (NDE) techniques based on expected damage mechanisms. Ana shares insights on recent advancements in radiography, field-based hardness testing, and imaging of hardness indents to assess effectiveness. The conversation also explores proper surface cleaning for inspections, the use of chemical composition analysis to detect degradation from galvanic corrosion, and the role of Integrity Operating Windows (IOWs). Additional topics include remote monitoring applications and innovations in remote inspection technology. Corrosion Chronicles is produced by Association Briefings.

In this episode, Ben Sprengard, managing director of innovation at Enerfab, sits down with co-hosts Heather Allain and Marc Cook to discuss fabrication considerations for duplex stainless steels. They explore key topics, including property comparisons to austenitic stainless steels, forming, machining, welding, phase transformation during cooling, welding QC, solution annealing, QC for duplex fabrication, in-service inspection, and heat exchanger specifics.

In this episode, Gary Whittaker, retired Engineering Fellow from Eastman Chemical and MTI Fellow, sits down with co-hosts Heather Allain and Marc Cook to recount some past failures he was involved in failure analysis on. They chat about: an API storage tank that leaked and contaminated a nearby river, some Nickel-Chrome-Moly alloy piping with stress cracking found due to indications on an associated clad vessel, and some Nickel-Moly alloy piping with stress cracking.

In this episode, Ben McCurry, Senior Expert of Materials Engineering and Inspection at BASF Corporation, joins co-hosts Heather Allain and Marc Cook to dive into the world of corrosion testing. They cover a wide range of topics, including the purpose of corrosion testing, lab testing versus in-situ methods, and the use of corrosion resistance tables. The discussion explores valuable insights from sister plants, decision-making criteria for conducting tests, and the design of coupons. They also tackle advanced topics like high-pressure/high-temperature data, the effects of aeration and agitation, post-exposure examination, grinding on coupons, field coupon accessibility, and how process conditions impact field testing results.

In this episode, Dale McIntyre, a designated professional with the Materials Technology Institute, joins co-hosts Heather Allain and Marc Cook to dive into the topic of anodic stress corrosion cracking, with a specific focus on chloride stress corrosion cracking (CSCC). They explore key SCC degradation mechanisms and discuss crucial factors in assessing CSCC risks. The conversation covers a range of topics, including reducing surface stress to minimize risk, temperature thresholds for CSCC, crack initiation timelines, NDE methods, the use of duplex stainless steel, insulation, painting, CSCC repair, and the role of castings in managing corrosion.

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. Show notes Ed would like to include his thanks to his colleagues Frank Upton, Rodney Ward and Chris Waddell.
