Abstract : In 1965 a series of blast tests were performed on several OCD valves, and it was discovered that the valves failed at overpressures as low as 4 psi. The failures occurred in the threads of the stud holding the valve disk to the stem. One of the 16-inch valves was subsequently modified by using tougher steel for the stud and nut and by increasing their threaded areas. A new series of blast tests on the modified valve were conducted as described in this report. (Author)
