Abstract
A system for preventing manway cover gasket over-compression utilizes machined surfaces on the top of eye bolt lugs on the side of a manway nozzle, machined compression stops on the periphery of the cover, and a specified distance between the top of the eye bolt lug and the manway nozzle edge to engage the stops at a predetermined amount of gasket compression. Force is distributed over an increased contact surface area between the manway cover and the bolt lugs to ensure that deformation occurs preferentially in the eye bolts before any other component in the manway cover system.
