Advice on using nondestructive testing to detect corrosion under insulation on process piping is the focus of a new podcast episode.

In an interview with editor Linda Becker, Suzy Vohsen, who handles marketing and customer experience for Gamma Graphics Services and LIXI Incorporated., talks about nondestructive inspection and testing for process piping, and how to handle corrosion under insulation if it is detected.

Podcast highlights include:

  • What is nondestructive inspection and testing, and why does it matter for process cooling? [0:33]
  • What is corrosion under insulation, or CUI? How does it get started? [2:16]
  • How does the moisture get introduced? [3:21]
  • How common is corrosion under insulation? [4:20]
  • Suppose someone decides that as a part of their proactive maintenance plan, they want to incorporate nondestructive testing to detect corrosion under insulation. What are the next steps? Do they just buy a tester and get started? Or is this a technique that you need a trained professional to perform? [5:25]
  • What are their testing options? [6:21]
  • So if you haven't performed any testing, a good place to start is to get a baseline to serve as a comparison for future testing results? [7:55]
  • Once you start an inspection plan, if you identify an area of leaking and repair it, how often should you check for corrosion under insulation under that repaired location? Where should you inspect for corrosion under insulation? [8:12]
  • Are there any codes that require such inspections? [10:35]
  • What are some of the benefits of inspection and nondestructive testing? [12:25]
  • Are there any places you should not use nondestructive testing in industrial cooling or refrigeration piping? [17:09]
  • How are Gamma Graphics Services and LIXI Inc. positioned to help a company perform nondestructive testing and inspection? [19:24]
  • From your perspective, what are some of the major challenges for the thermal process industry right now? [22:55]
