采用多种无损检测方法,对一台安全状况为4级且带大量超标缺陷的在役液化石油气球罐进行了定期检验。通过综合安全评定,鉴别并排除了其中的危险缺陷。既减少了返修工作量,又提高了球罐的安全状况等级。
A variety of nondestructive testing methods were used to regularly test a liquefied petroleum gas (LPG) balloon tank in service at a level 4 safety condition with a large number of oversized flaws. Through the integrated safety assessment, identify and eliminate one of the dangerous defects. Not only reduce the rework workload, but also improve the level of security of the spherical tank.
