Abstract

This investigation was conducted to examine the probable cause of failure of a drum arching tube at a 140 MW thermal power plant. Preliminary macroscopic examinations along with visual examination, optical microscopy, dimensional measurement, chemical analysis, hardness evaluation, thickness measurement to evaluate extent of damage were carried out to determine the probable cause/causes of failure. It was concluded that the combined effect of corrosion gouging and hydrogen damage were responsible for the failure. Appropriate remedial measures for avoiding such future failures are also recommended.
