Abstract:
1. A fuel storage container suitable for use in a fuel storage and delivery system for storing compressed natural gas fuel at pressures of about 20.7 MPa to 37.5 MPa (3000 psia-5440 psia) and delivering compressed natural gas fuel on demand for combustion in an engine, wherein said fuel storage container is constructed by joining together a plurality of discrete plates of materials comprising an ultra-high strength, low alloy steel containing less than 2.5 wt % nickel and having a tensile strength of at least about 900 MPa (130 ksi), and wherein joints between said discrete plates have adequate strength and toughness at said pressure conditions to contain said compressed natural gas, said joint strength being at least about 90% of the tensile strength of said ultra-high strength, low alloy steel.
