Abstract
Cylinders used to store compressed gases ranging from air and natural gas to hydorgen and inert compositions must be tested periodically usually by a hydrostatic test. In addition to insensitivity of the hydrotest to small service-induced defects, this test involves removal of the vessel from service and contamination of the vessel interior with water. Results of a program that compared acoustic emission testing with the hydrotest will be discussed showing much higher defect sensitivity for acoustic emission. These results combined with the ability to monitor in situ with acoustic emission recommend the latter in a number of applications.
