Abstract
A pressure vessel comprising a cylindrical stress liner, a pair of end plates, a plurality of annular shrink rings positioned about the circumference of the stress liner, and a plurality of coolant-filled annular cooling coils positioned about the shrink rings is disclosed. Nonuniform stress producing bending stresses in the shrink rings are eliminated by the method comprising the steps for detecting a stress concentration in a shrink ring and causing coolant to be recirculated from a reservoir through the coil about the shrink ring.
