ESTIMATION OF
RESIDUAL CONTACT
PRESSURE IN HYDRAULICALLY
EXPANDED CRA-LINED PIPE *
Abstract: The mechanically bonded CRA-lined pipe is developed to meet the need for corrosion-resistant alloy steel pipe. Residual contact pressure at the interface of lined pipe is important factor that governs the quality of lined pipe. A simplified theoretical method is presented to predict the residual contact pressure created by hydraulic pressure. The calculating equation related hydro-forming pressure to the residual contact pressure between two metal faces is derived. And the validation of the proposed equation is accomplished by comparing its result to those obtained by experimental investigation.
