Abstract
A pressure vessel having two separately formed vessel halves which are joined to form a compartment along a juncture, one of the halves further having a service port of a size sufficient to allow an individual to fully enter the vessel for working therein. The compartment is sealed at the juncture by a bonding layer surrounding both sides of the juncture inside and outside of the compartment, and is then wrapped circumferentially with tensioned, resin-wetted fiberglass filament. The vessel may have at least one fitted conduit which communicates with the interior of the compartment, the outer surface of the conduit adjacent to the compartment having an irregular surface which has been wrapped with resin-wetted, tensioned fiberglass filament. The juncture between the conduit and the compartment is overlayed with a layer of fiberglass material and subsequently coated with resin to form a rigid, fluid-tight seal. Resin-wetted fiberglass filaments are then wrapped circumferentially around the vessel, and additional resin is applied.
