Abstract
Abstract A cover for cylindrical pressure vessels wherein the cylindrical cover having a reduced diameter section at the end extends into the cylinder. A prop ring having a tubular section is positioned between the reduced diameter part of the cover and the cylinder for alignment and support of the cover with respect to the cylinder axis. A radial flange on the prop ring extends into a groove in the cylinder wall to position the cover longitudinally along the axis of the cylinder and prevent the cover from moving outward.
