Abstract
A segmented ring header is disposed between and welded to two pressure containment vessels. The segmented ring header comprises a first hemi-toroidal shell having a plurality of openings around its inner circumference shaped to mate with heat transfer tubes lining the first pressure containment vessel, a second hemi-toroidal shell having a plurality of openings around its inner circumference shaped to mate with heat transfer tubes lining the second pressure containment vessel, and a flat ring-shaped plate disposed between the first and second hemi-toroidal shells and welded therebetween. Both the first and second hemi-toroidal shells also have a plurality of openings along their outer circumference for directing the cooling fluid to a collection drum located outside of the pressure containment vessels. The hemi-toroidal shells are circumferentially welded to their respective pressure vessels along a locus located radially between the plurality of openings along the inner circumference of the shell and the plurality of openings along the outer circumference of the shell.
