When the boss gives you a lemon, how do you make it into lemonade?
That brand new, shiny vessel drove off the fabrication lot years ago and is now showing its age. And it did not age well.
Over the years, it became thinned out and lost its luster, an unsightly eyesore that nobody is thrilled to think about. And it’s your job to evaluate it for shutdown-necessary, tune-up candidacy.
Can you avoid the tune-up? Is this vessel perhaps bound for the junk yard altogether? How do you know? And what will you have to tell your boss?
Fortunately, there’s some documentation, some make and model information, the year of fabrication, some specs, so you have a place to start. You pull up PV Elite and enter what you can.
“Material”… hmm. You have the name of the material, but that purple ink isn’t really legible where the allowable stress is. Now what? You can guess, true, or use go-bys and slap on a safety factor, but there is a third option.
In PV Elite, you go to Tools - Configuration and a dialog opens. In the bottom right corner where the materials information is, there is a drop-down menu. Joy! Now you see ASME material data that goes all the way back to 1943. You find your material’s name and roughly the year of fabrication. Clicking on the material, you view the material properties and breathe. That solves one problem.
