Failure Analysis of API 5L (Grade B) Oil Field Separator Flowline Pipe

This paper presents the root cause failure analysis of an API 5L (Grade B) pipe that failed while in full well stream service in the oil and gas industry. The operating temperature ranged from 120 to 190 °F and was exposed to hydrogen sulfide (H 2 S) concentrations of 350–1000 ppm. Visual inspection...
