I worked for a major refinery here in Houston. We had a company check all of the bolting in the drum structure two times in 20 years. We did find a number of bolts missing and loose. We choose to do this about every 10 years. We had B-16 bolts in all of the hot oil lines. We didn’t have any problems with the bolting getting loose on any of our “hot” process piping.
