压力容器无损检测:球形储罐的无损检测技术

Pressure Vessel NDT: Nondestructive Testing Spherical Tanks

球形储罐是储存各种气体和液化气体的常用压力容器之一,在石油、化工、冶金和城市燃气供应等方面得到广泛使用。综述了球形储罐在制造、安装和使用过程中不同阶段可能出现的缺陷和分别采用的各种无损检测方法,包括射线检测、超声检测、磁粉检测、渗透检测、电磁涡流检测等技术。分别介绍了这些无损检测方法的特点。

The spherical tank is the storage of liquefied gases, and one of the commonly used pressure vessel, in the petroleum, chemical, metallurgical and city gas supply and so widely used. Summary of the spherical tank in the manufacture, installation and use may occur at different stages were used in a variety of defects and non-destructive testing methods, including testing, ultrasonic testing, magnetic particle testing, penetrant testing, eddy current testing techniques. Introduced the characteristics of these non-destructive testing methods.
