ABSTRACT:
A fluid apparatus including a fluid tank having a shell and defining a fluid containment compartment. A well is recessed into the fluid tank at an opening in the shell. The well has a well wall secured to the shell and a support ring at the shell opening and secured to and inside of the well wall. A cover plate is removably securable to the support ring to form a pressure-tight connection relative to the interior of the well such that the cover plate can retain in the well a pressure at least as great as the working pressure of the fluid in the compartment. This pressure-tight securement is preferably made by threading bolts through the plate and into drilled, tapped blind holes in the ring. The well can have a well head secured to the well wall and opposite to the shell opening. The well head in turn can be equipped with an internal manway cover openable into the tank and closable in a pressure-tight manner relative to the well wall.
