This paper carries out the pull-out test on the rubber gasket joint of ductile cast iron pipeline,which is commonly used in the urban water supply pipe network system. By applying tension at the ends of DN150,DN200 and DN300 pipe,the relationships between axial drawing force and displacement are obtained. The maximum axial force and the leakage displacement are given and the nonlinear relationships between axial drawing force and displacement are pointed out.
