Application of acoustic emission inspection in risk based inspection of atmospheric storage tank

China Special Equipment Inspection and Research Institute, Beijing 100029, China

摘要: 常压储罐传统的“周期性检验”模式容易发生 “检验过剩”或“检验不足”，所以对常压储罐进行基于风险的检验可以保证储罐运行中的风险处在可接受的范围内。利用储罐底板声发射检测数据修正风险评估中预设的底板腐蚀速率，再结合设备早期的检验结果、服役时间、设备损伤水平等进行综合风险评价，可使得风险评估的结果更加准确可靠，为检验策略的制定提供参考依据。

Abstract: The traditional “periodic inspection” mode of atmospheric storage tank is prone to “inspection surplus” or “inspection deficiency”, hence the risk based inspection of atmospheric storage tank is carried out to ensure that the risk in the operation of the tank is within the acceptable range. Using the acoustic emission testing data of tank bottom plate to modify the preset corrosion rate of the bottom plate in risk assessment, and combining with the early inspection results, service time, equipment damage level and other comprehensive risk assessment, the results of risk assessment are more accurate and reliable, which provides a reference for the formulation of inspection strategy.
