The Failure Analysis of Cracking on Pressure Gauge Joint
During the use of a certain gas distribution cabinet equipment,the pressure gauge joint with 06Cr19Ni10 material cracked and caused gas leakage.The methods of macroscopic observation,energy spectrum analysis and microstructure analysis were adopted.Finally,the brittle cracking of the pressure gauge joint under stress corrosion in chloride ion environment was analyzed.In order to ensure the reli-able operation of the equipment,the corresponding preventive measures were put forward.
