| Abstract: | In this text, aim for the phenomenon that breach with cooling wall pipes of the industry boiler,by the means of physical and chemical measuring method, material object analysis was carried on, as a result, defect such as crack and scab which leaded to serious stress corrosion in the intrinsic cooling wall pipe was the reason of the pipe breach. The systemic and scientific overhaul method was expound for the likeness event with cooling wall pipes of industry boiler. |
