I am trying to start a reliability program for safety critical valve. I know I need to do frequent quialty PMs. Does a valve get to a certain age that even if it passes a pm it should be changed anyway? It seems like critical valves should be on a changeout rotation. Am I correct on this?
Well during the winter the chemical will condense in the lines at 80*. During the summer it will remain a vapor, so to keep it constant they will just keep the lines steam traced..
At my new job at a chem plant they take the impulse lines and heat them to keep the liquid a vapor.... Has anyone ever seen this.... How does this work?
I just took a new job that uses alot of thermocouples! My old job used mostly RTDs, so I was looking for some trouble shooting tips for these and I had one question in particular.. Where my 2 T/C wires land on my Xmitter can I check voltage across it while the wires are still connected?
