The springs made from Inconel X-750 and used in Oxygen Scavenger service have failed by extensive corrosion within a short span of two years. The metallurgical compatibility between the material of spring and the process fluid is excellent.

After through investigations including deposits analysis of deposits found inside the valve it was found that vapors of the oxygen scavenger have been carried into the spring chamber and condensed into liquid and then degraded due to constant influx of air through a breather valve connected to the tank.

A detailed study of design of the chemical day tank was carried out it was found that the failure has actually occurred due to a gap of communication between the designer and supplier of the chemical day tank and the client.

This paper highlights the findings of the investigation carried out and the possible recommendations that can be put in place to avoid such untoward failures.
