Abstract

312,024. Vereinigte Stahlwerke Akt.- Ges., and Reichenbecher, G. Nov. 15, 1928. Pipes.-The end of a pipe 1, Fig. 3, is reinforced by expanding the heated free end by a mandrel 3 to form a socket 4 which is then pushed over the unexpanded portion by a ring 7. In a modification the mandrel is withdrawn after the first operation and then advanced after a plate 5, Fig. 2, has been interposed. The reinforced end may be consolidated by rolling by radial pressure or by the operation of expanding to form a socket end.
