For those living the dream of being a process safety professional know that one of the fundamental decisions we eventually have to make is how will we “class” our PSM/RMP covered process piping. For almost all of us, the best Piping Inspection RAGAGEP will be API 570, Piping Inspection Code and this RAGAGEP has a very ingenious way of “classifying” process piping based on its content and a degree of hazard. But like many RAGAGEPs, it provides us “guidance” and this opens the door to questions and incorrect decisions. In this article, I hope to convince you that our PSM/RMP covered process piping should land in Class 1.
