The endpiece comprises an outer shell(20) which tapers between an outer periphery and inner periphery, and which in the region of the inner periphery forms a flat flange contact face(17). The outer shell is dome-shaped or dish-shaped in construction, whereby the flat flange contact face forms the base of the dome or dish. An insulation(22) is provided between the inner(18) and outer shells. The inner and outer shells, at least in the region of the inner periphery, are interconnected by means of inert gas welding. |
