采用多种无损检测方法对1台安全状况为4级的,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。由此既减少了返修工作量,又提高了球罐的安全状况等级。
A number of non-destructive testing methods were used to conduct regular inspections on an in-service liquefied petroleum gas (LPG) balloon tank with a safety status of 4 and a large number of over-standard defects. Through the integrated safety assessment, identify and eliminate one of the dangerous defects. This will not only reduce the rework workload, but also improve the level of security of the tank.
