A new kind of hydroforming device was researched and developed to overcome difficulties in manufacturing mechanically boned clad pipe with conventional technologies. The operating functions and technical characteristics of this new device were described. Based on the elasticity-plasticity theory, the stresses and strains of liner and outer pipe were analyzed and the mechanism of hydraulic expansion method was studied theoretically. The calculating formulas related the residual contact pressures to hydroforming pressures between liner and outer pipe of the CRA-lined pipe products had been derived, and the theoretical analyses were verified by experimental results. It is shown experimentally that the new technology is feasible and can be applied in industrial production.
