An apparatus for use in conjunction with a pressure vessel, having a tubular conduit extending into the interior of the pressure vessel. The outer end of the conduit is rigidly fixed to one end of the pressure vessel in a pressure-tight connection. The inner end of the conduit is attached to a saddle at the other end of the pressure vessel, where the saddle is adapted to slidably receive the conduit such that upon expansion of the pressure vessel due to pressurization, the conduit will move independently relative to the saddle.

Expandable fiberglass pressure vessel having internal pipe connection

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.
