声发射检测是储罐底板腐蚀状态的在线定性检测技术,具有快捷、简便、费用低廉的特点,适用于腐蚀状态的快速筛查;漏磁检测结果直观,定位定量准确,是储罐底板腐蚀状态检测的有效手段。将声发射在线检测与漏磁检测技术联合检测,可以根据声发射检测结果,确定储罐的开罐检测计划,即可以保证储罐运行安全,又可以节约大量的维修费用,对于实现储罐检维修的科学化、高效化,减少和避免环境污染以及安全事故具有非常重要的意义。
Acoustic emission detection is an online qualitative detection technology for the corrosion status of tank bottom. It has the characteristics of fastness, simplicity and low cost. It is suitable for the rapid screening of corrosion status. The results of magnetic flux leakage test are intuitive and the positioning is accurate. Effective means of detection. The combination of acoustic emission on-line detection and magnetic flux leakage detection technology can be combined to detect the open tank inspection program based on acoustic emission test results, which can ensure the safe operation of the tank and save a large amount of maintenance costs. Maintenance of scientific, efficient, reduce and avoid environmental pollution and safety accidents is of great significance.
