Application Of Acoustic Technology Durring Safety Operation Of Tank In The Plants Of Oil Storage And Transportation

The tank is one of the most important equipment in oil transportation,transportation system, storage medium for crude oil, gasoline, diesel andother refined oil, these media are inflammable, explosive is dangerous, proneto tank process. Our country and the rest of the world according to their ownactual conditions to develop the relevant standards and norms, to require theuse of units of storage tank corrosion status of storage tank for regularinspection. Smooth operation to ensure that the storage tank safety state, toavoid the pollution caused by the destruction of ecosystem environment andthe accident.Because of these factors, we use the detection technology to achievesafe, reliable, flexible and effective. NDT technology, will provide a reliableguarantee for the smooth operation of safety, long cycle of operation of oilstorage and transportation equipment and facilities and transportation system,it has very important meaning. Periodic testing of storage tank is restricted bysite conditions, means and ways of detecting is limited. At present, the tankworld only accredited online detection method is acoustic emission detectionmethod. Acoustic emission technique is mainly used in the deformation andfracture of materials for acoustic materials locally because of the rapidrelease of energy produced, usually the signal strength is very weak, we useelectronic instruments sensitive (sensor) to receive and analysis, thus inferAE source location, leak, and judge the corrosion situation.In twentieth Century80time metaphase, acoustic emission detectiontechnology application in large storage tank in petrochemical units, has beenwidely used in petroleum, chemical, and mechanical manufacturing field.Acoustic emission technique is a mature nondestructive testing method, inthe petroleum chemical industry can be used for detection of pressure vessel,tank bottom leakage, the most advantage of the online detection and safetyassessment of storage tank, is of great significance to the safe operation ofthe enterprise safety in production, storage tank.
