Symposium Failure Prevention and Unconventional Failures
Presentation Title Metallurgical Failure Analysis of a Fractured Intermediate Coupling
Author(s) Craig J. Schroeder
On-Site Speaker (Planned) Craig J. Schroeder
Abstract Scope One section of a fractured intermediate coupling was received for metallurgical failure analysis. It was requested that the cause of failure be determined. The intermediate coupling was reportedly used in a sea water pumping assembly that cools a condenser for a power plant. It reportedly ran continuously at one speed and was made from ASTM A743 Grade CF3MN cast stainless steel. The coupling reportedly failed after approximately two years in service. Other couplings made from the same type of stainless steel in similar applications have reportedly been in service for decades without failing.
