| Abstract: | The plastic theory of metal forming is used to analyze the
forming processes and its feasibility of extruding and bulging large strain multi way pipes
directly with tubes. The effect of various bulging mediums is discussed. It is seen that fluid
material fits extrude and bulge. The formula to calculate the dimension of the tube and the medium
is also given. The largest ratio of the height to the diameter of the pipe is 3.6. |

| Keywords: | multi way pipes bulging medium forming limit |
