ABSTRACT:
An end wall closure device for supporting the end wall of a pressure vessel against axial movement when subjected to load conditions. A retaining member made up of a segmented shear key and a segmented compression key is inserted within an internal groove provided within the vessel casing. The shear key is seated in a recessed shoulder formed in the end wall and is provided with a pair of raised moment control pads which, in assembly, act upon the compression key and the casing wall. The pads are strategically positioned to negate the bending moments acting on the retaining member thus minimizing the deflection of the retaining member when placed under load.
