Narrative
A one-inch threaded steel pipe nipple failed inside nustar's big spring terminal. The nipple was located on booster pump 16 and was part of a thermal relief system. The nipple was sent to a third-party laboratory for analysis. Update - there were two failed threaded nipples within the one-inch thermal relief piping assembly. The cause of the failures was mechanical fatigue due to excessive vibration of the unit 16 suction piping and header manifold. Cracking initiated in the pipe thread roots and propagated through wall and around the circumference of the pipe nipples.
