  • Patent number: 11141930
    Abstract: A method for molding a composite pressure vessel liner to secure a boss to the liner is described. The method comprises providing a moldable liner having an end section with a neck and a port. A boss is positioned around the neck of the liner and the liner is heated and pressure is applied to mold the liner to form to the shape of the boss. The angle of the molded liner secures the boss in place around the liner and it is able to withstand high pressures. A tool for molding the liner and a method for using the tool is also described. The tool comprises a tool body and a pipe having external threads. The tool body abuts the liner and the boss. Winding the pipe exerts pressure on the liner, which when heated, forces the liner to mold to the shape of the boss.
