Pipeline Failure by Transit Fatigue
A spiral welded pipeline failure that occurred during hydrotest was attributed to transit fatigue, caused during highway transportation. Transit fatigue during rail, road and marine transportation is a well-known failure mechanism. American Petroleum Institute (API) standards for prevention of transit fatigue during railroad and marine transportation are already established. Transit fatigue during highway transportation is rarely reported, and there is no industry standard addressing controls for line pipe transportation by highway.
