Failure Analysis and Prevention of Pressure Vessels in a Natural Gas Processing Plant

Taking a failed container in a natural gas treatment plant as an example, several methods were detecting pressure vessel cracks. Based on the test results, it is conduded that the failure of the pressure vessel was due to stress corrosion, and then the prevention and control measures of stress corrosion of pressure vessels and pipings were proposed. These may provide some reference for the management on pressure vessels and pipings of other natural gas processing devices.
