ABSTRACT:
A heat exchanger shell closure utilizing a tapered split ring is disclosed. The split ring of the invention has a tapered inner surface which fits into a corresponding tapered groove in a tube sheet barrel. A backup flange fits over the split ring, forcing the split ring into the deepest and forwardmost part of the groove, thereby preventing longitudinal movement of the split ring and the resulting movement and wear of a sealing ring which is held in place by the split ring as the heat exchanger undergoes load variations.
