..., respectively) from the suction line were analyzed. Evidence of overall thinning of the elbow and pipe material and ductile tearing of fractures indicated that the feed water pipe failed as a result of an erosion corrosion mechanism, which thinned the wall sufficiently to cause rapid, ductile tearing...

Further analysis of the boiler operation revealed that operational changes made in the last year of service caused an increase in velocity of the water/steam mixture. It was recommended that the operating parameters for the boiler be reevaluated...
