| Abstract: | Through experimental investigation and destructive comparision for three multilayer wrapped high- pressure vessels using acoustic emission method,an acoustic emission testing technology of multilayer wrapped pressure vessels was studied and the evaluation criterion of testing results were established.The method was applied to 80 urea reactors and many crack flaws were found.These applications showed that acoustic emission testing technology of multilayer wrapped urea reactors was effective. |
