ABSTRACT:
A filament-wound vessel for containing corrosive and pressurized fluids is disclosed. The vessel comprises a thermoplastic resin inner liner having a cylindrical sidewall and integral oblate, ellipsoidal end sections, and axially aligned access openings at each end of the vessel. One of the openings has a relatively wide diameter compared to the other opening, and a tank fitting is mounted in the wide diameter opening. The tank fitting comprises a fiber-reinforced plastic female member having a cylindrical end projecting into the wide diameter opening of the inner liner and a cylindrical neck portion projecting from the opening. An annular boss is provided between the cylindrical end and the cylindrical neck and rests on an exteriorly facing annular portion of the end section. A sealing ribbon, which comprises a substantially uniform mixture of a thermoplastic material and ferromagnetic particles, seals the boss to the annular portion upon the application of electromagnetic energy. The sidewall of the vessel is provided with a circumferential winding, and the entire sidewall of the vessel is provided with a helical winding which extends over the end sections to provide further reinforcement for the annular bosses. A circumferential winding is provided around the neck section to ensure the dimensional stability of the neck section upon the application of internal pressure to the tank.
