摘要：A new hydroforming process for manufacturing corrosion-resistant-alloy(CRA)-lined pipe is proposed to overcome the disadvantages in existing technologies, and a new kindof hydraulic expansion device for bimetallic CRA-lined pipe has been researched and developed. Itsoperational principal and technical characteristic is also introduced. The stress and strain in theliner and outer pipe during the hydroforming process have been analyzed and the mechanism ofhydraulic expansion method is studied theoretically. The final forming pressure formula is suggestedand the theoretical analysis is verified by experimental investigation. The results indicate thatthe new technology is feasible and can be applied in industrial production.
