In pipe neck-spinning process, the feed speed has great significant on pipe deformation and smoothly proceeding of spinning. In this paper, the nonlinear finite element software SuperForm is used to simulate the deformation in pipe multi-pass neck-spinning process, the stress distribution inside and outside of the pipe deformation zone, as well as the stress on spinning roller. The results show that, after nine times neck-spinning, the maximum deformation locates in the pipe mouth, and the stress on the outside of the pipe is larger than the inside. With the increasing feeding rate, the thickness of pipe necking deformation zone decreases, while the pipe length is shortened to 4.66mm. The stress in X direction on spinning roller increases with the prolonging of time in the medium term of spinning, but that in Y direction did not changes significantly.
