Abstract
A tank for a railway tank car includes an outer tank, a nozzle, a fittings plate, and a set of pipes. The nozzle protrudes through the outer tank such that an outer edge of the nozzle extends past an exterior surface of the outer tank. An intersection between the nozzle and the outer tank defines an opening in the outer tank. The fittings plate is welded to the nozzle around the outer edge of the nozzle. The set of pipes pass through the fittings plate and into the outer tank through the nozzle. The set of pipes includes pipes to load and/or unload fluid from the tank.

A tank for a railway tank car comprising:
- an outer tank;
- a nozzle protruding through the outer tank, wherein:
- an outer edge of the nozzle extends past an exterior surface of the outer tank;
- and
- an intersection between the nozzle and the outer tank defines an opening in the outer tank;
- a fittings plate welded to the nozzle around the outer edge of the nozzle;
- a set of pipes passing through the fittings plate and into the outer tank through the nozzle, the set of pipes comprising at least one of pipes to load fluid into the tank and pipes to unload fluid from the tank;
- a cover plate, wherein:
- the fittings plate defines a set of openings, each opening of the fittings plate associated with a pipe of the set of pipes that passes through the opening;
- the cover plate defines a hole, wherein:
- a pipe of the set of pipes passes through the hole;
- and

A method for manufacturing a tank for a railway tank car comprising:
- coupling a nozzle to an outer tank, wherein:
- the nozzle is configured to protrude through the outer tank, such that an outer edge of the nozzle extends past an exterior surface of the outer tank;
- and
- an intersection between the nozzle and the outer tank defines an opening in the outer tank;
- passing a set of pipes through the nozzle, the set of pipes comprising at least one of pipes to load fluid into the tank and pipes to unload fluid from the tank;
- placing a fittings plate over the outer edge of the nozzle, the fittings plate defining a set of openings, each opening of the set of openings associated with a pipe of the set of pipes, wherein placing the fittings plate over the outer edge of the nozzle comprises passing each pipe of the set of pipes through the associated opening of the set of openings;
- welding the fittings plate to the nozzle around the outer edge of the nozzle;
- placing a cover plate on the fittings plate, the cover plate defining a hole, wherein:
- placing the cover plate on the fittings plate comprises passing a pipe of the set of pipes through the hole;
- and
- a diameter of the opening of the set of openings that is associated with the pipe is larger than a diameter of the hole;
- and
- welding the cover plate to the fittings plate around an outer perimeter of the cover plate.
