Tube Failures in High Pressure Boilers

There are twenty-two primary reasons for tube failures in a boiler, which can be classified under six major groups. They can be analyzed and corrective and preventive action can taken. Good operating and maintenance practice reduces tube failures. Tube failures during the initial operation period, the normal operation period, and after ten to fifteen years operation show different trends.
