A tube end piece for a separately manufactured tube mantle and method for assembly. The solutions presented in prior art for providing tube mantles with an end piece are generally satisfactory, except that the number of manufacturing steps is large compared with conventional manufacturing methods. With the aid of this invention, one step at least can be eliminated in the joining of the end piece and the mantle. The end piece is provided with an annular extension which can be pressed down so that it remains in its place, clamping the interposed mantle fast to the end piece. Thus by using the tube end piece it becomes possible to perform the joint seaming of the end piece to the tube mantle in one work step. |
