| Abstract: | The cracking occurred in dehydration tower was described in this article. By using optical microscope, scanning electron microscope and energy--depressive spectrum equipment, the shape of the cracks and the products of corrosion were analyzed. It was proved that the main cause of crack was stress corrosion. Then, some useful protecting methods were presented. |
