Discussion on Non-destructive Testing Techniques of Pressure Special Equipments

Pressure vessels ale very important equipments which widely used in industrial production and people＇s daily life, But they also have potential danger. The nondestructive testing technique plays one of the most important roles for insuring manufacturing quality and operation safety of pressure vessels. This paper reviews the nondestructive testing technology of pressure vessels manufacturing.and using process, including ultrasound, ray, magnetic powder, osmosis, unconventional testing technology, and it introduces all kinds of non-destructive inspection technalogy＇s good and bad aspects and the selection principle, discussed the domestic non-destructive inspection technology present situation and problems.
