Abstract:
1. An end fitting for a cylindrical pressure vessel, the end fitting integrally joined to the pressure vessel, the pressure vessel having an outer cylindrical wall, the end fitting comprising: a partial toroidal shell defining a hole, and including an outermost width that is attached to the outer cylindrical wall; a centrally disposed piece comprising a pipe and a center end fitting, the centrally disposed piece closing the hole; and structural members that connect either the centrally disposed piece and/or the toroidal shell to the outer cylindrical wall or to an extension of the outer cylindrical wall, wherein the end fitting is structured so that a fraction of the longitudinal forces from internal pressure is transmitted to the outer cylindrical wall or the extension by means of the structural members and a remainder of the longitudinal forces from the internal pressure is transmitted directly to the outer cylindrical wall.
