Development of a 40,000 Gallon High Profile, Collapsible, Rubberized Fabric, Fuel Storage Tank

摘要

This report describes the development and testing of an experimental 40,000 gallon collapsible, rubberized fabric, high-profile, petroleum fuel storage tank. The objective of the project was to develop a tank having a 40,000 gallon capacity which would occupy approximately the same ground area as a standard 20,000 gallon tank and meet the performance requirements of MIL-ST-82123. The tank was developed based upon a military adaptation of a commercial item (MACI) study following which a prototype unit was fabricated and tested. The prototype tank assembly completed the functional testing without leakage but fitting collars were observed to lift during the stand test and overload test. A stress concentration was also seen to exist between the fill/discharge fittings and the body seams caused by the closeness of the fittings to the seams. The integrity of the tank was not affected by these conditions. During the overload test it was noticed that an approximate 2' long area of one end seam showed excessive elongation on the seam edge gum strip. The fitting collars and end seam were repaired prior to delivery of the tank to the Army. All material tests were passed.
