摘要
大型常压储罐检测传统方式是停产、开罐、清洗、喷砂除锈、置换、开始检测,检测周期长,费用高,效率低且随机性较大。而采用在线声发射检测技术,对储罐在线检测、评价及分级,对发现问题的储罐再进行开罐检测,既节省了大量费用,又缩短了储罐停产时间。
The paper introduces the traditional testing methods of large atmospheric pressure storage tanks such as the shutdown, opening tank, cleaning, sand blasting, rust removal, part replacementand starting testing. In this case it will results in the long testingcycle, highcost, and low efficiencywitha very high randomness. Whilewith onlineacousticemissiontesting technology, it isthe first step to conduct the on-line testing, evaluation and classification of storage tanks, afterwards open the storage tank if any defect is found during the testing, in this way it will not only save a lot of cost, but also shorten the storage tankshutdown time.
