Abstract

Plastic pipe is removed from a mandrel by forming two circumferential grooves of different depth in the pipe wall, attaching a holding means to the pipe where the holding means has projections which fit into the grooves, and then applying an axial force to the holder. This method prevents damage to the mandrel and the pipe.
