Abstract
Abstract : The 1200cfm and 6OOcfm gas filter housings were investigated using finite element analysis techniques to examine if ASTM A554, Type 304 stainless steel (yield strength = 25,000 lb/sq in) could be substituted for the currently specified AMS5563, Type 304 stainless steel (yield strength = 75,000 lb/sq in). The factor of safety for the l200cfm filter housing was determined to be 7.9 for the AMS5563 steel and 2.6 for the proposed ASTM A554 steel. The factor of safety for the 600cfm filter was determined to be 26.3 for the AMS5563 steel and 8.7 for the proposed ASTM A554 steel. The analysis results show that the fully loaded filter housings can be stacked at least two units high for the l2OOcfm and 6OOcfm gas filters. The analysis results also show that the support arrangement does not affect the maximum stresses or deflections.
