| 摘 要： | 某油罐底板发生了渗漏，采用AE声发射技术在油罐在用状态下检测出底板渗漏点的大致位置后，倒空油罐，对油罐内部管壁和底板进行热水循环清洗。用N2置换内部的油气，用轴流风机强制通风，检测罐内气体符合呼吸和防爆要求后，从人孔进入罐内。通过渗透检测和真空箱检测的方法精确找出缺陷位置，采用充N2隔离油气、浇水降温、钻孔等一系列措施挖除缺陷，更换底板下缺陷附件的含油沥青砂层。最后，在缺陷所在位置上焊接补丁钢板，成功地进行了易燃易爆油罐底板渗漏的修补。

| Abstract: | A certain oil tank had a leakage point on a certain bottom plate,after had found out the location of the leakage point approximately under living oil tank by the technology of acoustic emission detection(AE-detection),and emptied the oil tank.Cleaned the interior shell plates and bottom plates by circulate hot water,replaced the oil gas in the oil tank with nitrogen-filling,and inbreathed fresh atmosphere compulsively with blower.And the entry the oil tank through the manhole for following repair-working.After had found out the location of the leakage point precisely by penetrate test detection(PT-detection)and vacuum-box test detection,separated oil gas with nitrogen-filling,fell down temperature by irrigating cool water,excavated out the bug by drilling,the replaced the contain oil asphaltum-sand layer around the bug below the bottom plates,welded steel mend-plate on the bug in the end,repaired the bug on the bottom plate of the oil tank under flammability and explosive circumstance. |
