大型球形储罐内表面荧光磁粉检测实例分析
|
摘要
球罐因其承载能力大,占地面积小,节省钢材的特点,在大型化工装置与中广泛应用。但也因此具有检验难度高,事故风险大,事故后果严重的特点。荧光磁粉检测具有对比度高、灵敏度高、利于暗处检验的特点,适用于大型球罐内表面检测。本文对某大型化工厂球罐内表面检测实例进行分析,阐述荧光磁粉检测的实例应用,并对裂纹检出要点进行讨论。
The Spherical tanks are widely used in large-scale chemical plants because of their large carrying capacity,small footprint and steel saving.But it also has the characteristics of high test difficulty,big accident risk and serious accident consequence.Fluorescent magnetic particle testing has the characteristics of high contrast,high sensitivity and favorable for dark inspection.It is suitable for internal surface inspection of large spherical tanks.A case study on internal surface test of spherical tank in a large chemical plant was carried out.The application of fluorescent magnetic particle inspection was expounded,as well as the key points of crack detection.
