| Abstract: | Based on the AE signal character because of the marine pipes and valves' leak and the open and close movement,this paper discourses upon the status surveillance method and the experimentation and research of AE for the marine pipes and valves.This paper introduces AE surveillance technology,in which transducers were fixed on the pipes or valves,thus in virtue of it we can realize the status of key valves' work and functions,realize the long-distance and real time and lossless and continual surveillance,espe... |
