An upheaval buckling prediction approach is proposed for a high-temperature cased insulated flowline (CIF). Based on the tensile cracking and compression crushing analyses of the CIF concrete-weighted coats, the curvature-related nonlinear bending stiffnesses of CIF systems are discussed. A changeable stiffness is included in this buckling prediction approach developed using a transfer matrix method. Due to a relatively low bending stiffness, greater curvature and higher bending stress would be induced in the carrier pipe at field-joint positions in the buckling response of CIF systems, while the shear force change would be induced in the five pipe coats of CIF systems. Using the approach developed in this paper, the field-joint stress of a CIF carrier pipe and the interlayer shear forces of the CIF pipe coats can be obtained along the buckling path of the CIF systems by plotting the relationship curves between the carrier pipe axial forces and the CIF buckle lengths.
