Storage Tank Acoustic Emission Detection Technology Application Research

With the rapid development of global economy, increasing petroleum demand and thearpid development of petroleum industry, petroleum reserve has been generally regarded, andstorage tank is an essential equipment of petroleum product?丁ank is affected by vairous factorsand inevitably injured in use process for long-term.. In order to ensure the safety of storagetanks, the tank was detected. Conventional nondestructive testing methods needs to stopproduction or opening tank conditions, with high detection cost, long test time, large laborintensity, which will cause a certain degree of environmental pollution, and diiffcult to achievea comprehensive detection. Acoustic emission detection technology advantage on-line,dynamic, integral detection, high sensitivity, low detection cost, short detecting time, highdetection eiffciency, low labor intensity and so on.Bottom plate of storage tank is most likely to occur problem, which main bottom leakageand corrosion tank defect can produce acoustic emission effective sound source, so acousticemission detection technology is researched on tank bottom corrosion and leakage to theactual situation. Through analysis of the stoarge tank acoustic emission source on tank bottomleakage and corrosion and simulation of tank floor leakage expeirment, the results showeffective active acoustic source of vairation and localization method. The storage tank acousticemission detection technology can be applied. The actual storage tank acoustic emissiondetection online application was executed, testing results was checked by conventionalnondestructive testing methods, which show that storage tank acoustic emission on-linedetection is effective and feasible.The results of research and application show that storage tank acoustic emission on-linedetection technology has very important application value.
