The mechanical properties of the rubber gasketed joints on ductile iron pipes

The mechanical properties of the rubber gasketed joints on ductile iron pipes are analyzed, which are commonly used in the water supply system. The theoretical calculation formulas of the maximum pull force and moment in the the rubber gasketed joints are deduced, and the maximum safe rotation is given. Based on the early test results, the stiffness matrix of the rubber gasketed joints on ductile iron pipes is established. Outcome of the research project can offer theoretical and technical support for the numerical simulations on the rubber gasketed joints.
