Hydrofluoric Acid and Anhydrous Hydrogen Fluoride - Part 2

About this episode

The episode continues the discussion on hydrofluoric acid and anhydrous hydrogen fluoride, focusing on detection techniques, material selection, and real-world applications.

In this episode, the second installment of a two-part series, Bert Jennings, owner of Jennings Materials Consulting in Spring, Texas, rejoins co-hosts Heather Allain and Marc Cook to continue their discussion on hydrofluoric acid (HF) and anhydrous hydrogen fluoride (AHF) service. Building on Part 1, the conversation shifts to detection, materials, and real-world application. Bert outlines key NDE techniques for identifying cracking and hydrogen blistering, then dives into weld practices and the importance of proper stress relief in carbon steel systems. The group also explores alternative materials, including austenitic stainless steels, ceramics, and glass, along with a “learn from failures” story that highlights the consequences of small oversights. The episode wraps with insights on nickel alloys, welding challenges, and the role of FRP and fluoroplastics—reinforcing that success in HF service depends on both material selection and execution. This episode is sponsored by Tricor Metals and Rolled Alloys.
