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.

A fiberglass pressure vessel of the type that expands when pressurized comprising: two separately formed vessel halves each having exposed edges which are joined to form a compartment along a juncture, one of said vessel halves further having a service port of a size sufficient to allow an individual to fully enter said vessel for working therein, said compartment sealed at said juncture by a bonding layer surrounding both sides of said juncture inside and outside of said compartment, said compartment wrapped circumferentially with tensioned fibrglass filament in one direction substantially transverse to said juncture and in another direction substantially parallel to said juncture, said vessel provided with at least one tubular conduit of a material dissimilar to fiberglass and attached in a pressure tight connection to the vessel, said conduit having an outer and an inner end communicating with the interior of said compartment, said conduit having an irregular outer surface adjacent the exterior of said compartment, a second layer of fiberglass filament seated in said irregular surface for providing a mechanical interlocking engagement between the conduit and the fiberglass filaments, a separate fiberglass layer overlaying said fiberglass filament and joined to said compartment, said layer of tensioned fiberglass filament wrapped substantially parallel to said juncture being wrapped around said separate fiberglass layer and said second layer of fiberglass filament to integrally bond the tubular conduit to the compartment, and said compartment provided with a saddle for slidably receiving said inner end of said tubular conduit, said tubular conduit extending through said vessel half and being sealed and rigidly held thereto, wherein expansion of the compartment upon pressurization will allow said conduit to move independently relative to said saddle.
