Abstract
A thin-walled pressure vessel having an improved insert. The insert increases the thickness of a portion of a pressure vessel's sidewall to allow the sidewall to accommodate a port. The insert comprises a main body structural member defining an opening through its center. The opening through the body member communicates with openings in an inner liner and an outer shell which comprise the vessel to provide an opening through the sidewall of the vessel. A fitting disposed in pressure contact with the main body member circumjacent the opening lines the walls of the opening in the body member and engages a portion of the main body member with an annual flange to restrain expansions of the body member at increasing temperatures while defining a port which maintains a constant shape and size for receiving other fittings.
