Cracking Investigation of Vaporizer Tubes
- 103 Downloads
This article describes the results of an investigation into failures of washing phenol vaporizer tubes. Thorough analyses including visual examination, chemical testing, fractography, metallography, heat treatment, and hardness testing have shown that the vaporizer tube failure is attributed to intergranular corrosion. The failure contributing factors are identified and elucidated.
