| Abstract: | A new kind of hydroforming device for manufacturing bimetal-lined pipe was designed and developed to overcome the disadvantages in conventional technologies, and its operational principle and technical characteristics were introduced. Based on elasticity-plasticity theory, the stress and strain in the inner and outer pipe during the hydroforming process were analyzed and the mechanism of hydraulic expansion method was studied. By using deformation condition of compatibility, the calculating formula related hydroforming pressure to the residual contact pressure at interfaces of bimetal-lined pipe was derived and verified by experiments. The results demonstrate that the new technology is feasible and can be applied in industrial production. |
