Prediction of liner wrinkling during high strain bending of mechanically lined pipe
peer-reviewed A high demand for transport of corrosive fluids subsea has generated interest in solid corrosion resistant alloy (CRA) and bi-metal pipes. Bi-metal pipes, including hot-roll bonded (HRB) clad and mechanically lined pipes (MLP), are made of a carbon steel (CS) pipe lined with a CRA laye...
