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.

Bank Tube Failures in Bi-drum Boilers - IDC-Online

2019-2-4 · Reasons for bank tube failure The main reason for bank tube failure due to expanded joint failure is inadequate expansion. Many times it is very difficult to measure each tube ID for checking the percentage thinning, hence it is a practice to measure a few tubes in every 100 or 200 tubes and fix the expander torque to get the required thinning.
