TESTS ON ATLAS BLAST VALVES
Abstract
The WS-107A-1 Silo Blast Closures, 16- and 42-in. were subjected to a series of performance experiments. These performance experiments were designed to simulate the actual operating conditions and/or environments to which the closures would be subjected during normal operation. The 16-in. closures reacted satisfactorily to all the performance experiments with the exception of cold environments. They were subjected to maximum test blast load without failure. During the cold environment experiments, pressure leaks in the hydraulic system of the closures developed at approximately 0 F. These pressure leaks resulted from the shrinkage of the teflon seals in the system. The 42-in. closures responded satisfactorily only to the hot environment experiments. The temperature of the 42-in. closures was raised to 300 F before any failures occurred. Pressure leaks in the hydraulic system occurred when the closures were air-blast loaded. Extensive damage developed during repeated cycling experiments. (Author)
