Abstract
An improved pressure vessel which maintains the press-fit between the concentric rings of different material at all temperatures up to the maximum operating temperature by providing an intermediate ring between the inner ring having a coefficient of expansion less than the coefficient of the outer ring wherein the intermediate ring has a coefficient of expansion greater than the outer ring, the radial thickness of the intermediate ring is determined in terms of the radial thicknesses and coefficients of expansion of the inner and outer rings such that upon the pressure vessel operating to the maximum temperature the combined expansions or increases in radial thicknesses of the inner and intermediate rings are equal, or substantially equal to, the expansion or increase in radial thickness of the outer ring.
