Abstract

During long-time operation, thermal deformation of heat exchange pipe weaken the capability and reduce the reliability of heat transfer system, especially the heat exchange pipe with initial bending in high temperature storage condition will make problem more seriously. The finite element simulation study based on ABAQUS code was carried out to explore thermal deformation behavior of heat exchange pipe and interaction between pipe-soil interfaces, through establishing the typical initial bending model of pipe body and the description of the basic equations The distribution law of effective stress, displacement and plastic strain at feature edges and the cross section were obtained. The result showed that value of effective stress, displacement and plastic strain distribution of soil are cyclical fluctuation change with different bending deflection and bending direction, the location of maximum bending deflection is the most serious heat transfer attenuation areas.
