Narrative
Nustar discovered a crude oil release inside its big spring terminal and immediately shut down its pipeline system. A 1-inch valve was utilized to isolate a failed threaded steel pipe nipple used for chemical injection. Clean up and remediation of the site has been completed. The cause of the accident is under investigation. Update - an analysis of the failed 1/4 -inch threaded pipe nipple concluded that the failure occurred due to mechanical fatigue in bending. Cyclic stresses were likely generated by movement of the valve and fittings attached to the threaded pipe nipple due to mechanical loading transmitted through piping and structure from pumping equipment. The steel nipple has been replaced.
