In the world of process safety, pressure vessel safety plays a major role! Yet many facilities do not have engineers available to them and thus some will struggle with which code(s) apply and what must be done to maintain their pressure vessel(s) in tip top safety shape. This is my cheat sheet that I have used for years that helped me when others were talking BPVC lingo. It list each section of the American Society of mechanical Engineers (ASME) Boiler and Pressure Vessel Code and provides a brief explanation of what is in each section of the code. In very general terms, most (but not all) pressure vessels used in a PSM/RMP covered process will be built to “ASME Section VIII” – to better understand what this means, see below…
