Nondestructive Testing Method and Testing Time Choice of Pressure Equipment

The engineering risk of pressure equipment is closely related on the structure and material of equipment as well as the parameters such as pressure, temperature, medium environment, etc., which it withstands. In order to reduce and control the engineering risk of the pressure equipment, appropriate nondestructive testing method and testing chance must be adopted at the stages of design, manufacture and installation to control the product quality and assess its safety status at the operation stage of pressure equipment. In this paper the importance of nondestructive testing method and chance selection for pressure equipment is discussed based on engineering cases. This paper shows that nondestructive testing technique is an important means for product quality control of pressure equipment and is also important guarantee for its safe operation. Under the condition that appropriate nondestructive testing method and testing chance are selected, the engineering risk of pressure equipment can be minimized.Copyright © 2013 by ASME
