Abstract
A pressure vessel has an interior chamber and includes an outer shell, a boss, and an internal liner disposed within the outer shell. The boss includes a port extending between the interior chamber and an exterior of the pressure vessel; and an annular flange extending radially from the port and having an exterior surface and an interior surface. The liner includes an exterior portion adjacent the exterior surface of the flange; an interior portion adjacent the interior surface of the flange; and a vent in the interior portion. A method for forming a pressure vessel includes mounting a boss on a mandrel, flowing a non-metallic polymer around a flange of the boss to form an internal liner of the pressure vessel, forming a vent in an interior portion of the liner; and forming an outer shell surrounding the liner and at least a portion of the flange of the boss.
