This is the third and final part of the blog trilogy relating to life management of pressure swing absorber (PSA) vessels. In this article, we will explain how to develop a life management plan and an inspection strategy based on fatigue analysis. In Part 1, we explored the significance of measuring longitudinal weld peaking in […]
In the first part of our blog series on the Life Management of Pressure Swing Absorbers (PSA), we discussed the importance of accurately measuring weld peaking and how it influences stress and fatigue life. As we delve into the second part of this series, our focus shifts to the quality of Non-Destructive Testing (NDT) inspections, […]
Introducing the first blog in a trilogy about the life management and assessment of Pressure Swing Absorber (PSA) vessels. Can the lifespan of a PSA can be extended beyond its designed lifespan of 20 to 30 years of service? Operators often start worrying about the integrity of their PSA vessels as these approach the end […]
Weld peaking or out-of-roundness affecting PSAs is evaluated, highlighting the value of conducting peaking measurements to determine a PSA’s inherent stress concentration. Below is an excerpt from the article. This article was published in the Revamps Issue of PTQ 2022 Can the life of a pressure swing absorber (PSA) be extended beyond its intended design […]
