Ammonia Stress Corrosion Cracking of Admiralty Brass Heat Exchanger Tubes in Refinery Cooling Water System

Sudharsanan Soundararajan
... for failure as Ammonia Stress Corrosion Cracking. Process parameter analysis revealed that the leak from a recycle gas cooler in Hydrocracker unit as the possible source for ammonia in cooling water system. The full-length tube expansion for plate type fins is the source for residual stress. This paper briefs...
