    Column Internals

    In this episode, Danny Mock, managing partner for M10 Process Equipment, Inc., joins co-hosts Heather Allain and Marc Cook to take listeners inside the world of column internals and the fundamentals that drive mass-transfer performance. Danny breaks down what mass-transfer equipment is and how internals efficiency is evaluated, offering practical insight into design considerations that influence reliability and long-term operation. He discusses the importance of selecting materials with appropriate corrosion allowances, how internals are attached and supported, and what engineers should know about bolted fasteners, dissimilar metals, tray flatness, and the risks associated with creep and thermal expansion. The conversation also covers column fires, static charge generation, and the role of random packing in modern column design. Whether you're troubleshooting existing towers or designing new equipment, this episode provides a comprehensive look at the details that matter most inside a process column.

    Explosion Cladding

    In this episode, Mukesh Ahlavadi, Global Director of the Chemicals Market at NobelClad, joins co-hosts Heather Allain and Marc Cook to explore the world of metal cladding and its critical role in modern engineering applications. Together, they provide an overview of hot roll bonding versus explosion cladding, examining the key drivers behind each process and why industries turn to cladding for enhanced material performance and corrosion resistance. Mukesh walks through essential fabrication considerations, including the use of batten strips, interlayers, and post-cladding operations, while sharing insights into heat treatment, forming clad plate, and lessons learned from a 1990s clad failure. Listeners will gain a clear understanding of how explosion cladding was discovered, the mechanics of the process, and how the distinctive wave pattern at the clad interface reflects quality and bonding integrity.

    How a Materials Lab Works

    In this episode, Jennifer Larimore and Avery Boyer, Materials Engineers at Chemours, join co-hosts Heather Allain and Marc Cook to share an inside look at how a materials lab works. Jennifer and Avery walk through the step-by-step process of analyzing samples—from sectioning, cleaning, reviewing documentation and photographing through the final wrap up of documenting and communicating findings to the customer. They discuss analysis methods like nondestructive evaluation, XRF identification, hardness, fracture testing, polishing and metallography to uncover critical material properties. The discussion also explores the importance of turning technical findings into clear, actionable recommendations. Throughout the conversation, the guests highlight how these practices help solve real-world challenges, prevent failures, and ensure long-term reliability.   This episode is sponsored by Tricor Metals and Webco Industries.   Corrosion Chronicles is produced by Association Briefings.

    Materials Selection During Project Execution

    In this episode, Cathleen Shargay, Advisor of Materials and Welding Engineering at Becht, joins co-hosts Heather Allain and Marc Cook to explore the complexities of materials selection during project execution. The conversation covers a wide range of essential topics, from understanding what materials selection diagrams (MSDs) are and how they interface with process engineering, to evaluating life cycle cost inputs and establishing design life. Cathleen also unpacks how MSDs relate to Integrity Operating Windows (IOWs) and Corrosion Control Documents (CCDs), and how these tools work together to support informed decision-making. The episode dives into strategies for managing excursions, assessing corrosion circuits, and understanding the consequences of material failure. Finally, the discussion looks ahead to how artificial intelligence is beginning to shape materials selection and analysis in the future of engineering.
