Abstract

Abstract: This paper establishes a mathematical model for calculating the temperature rise along the styrene pipeline, taking into account the axial and radial heat transfer of the styrene pipeline and the influence of the frictional heat generated by the medium in pipeline on the temperature rise. The characteristics of the axial and radial heat transfer of pipeline are analyzed, the heat transfer calculation methods in different directions are given, and the thermodynamic properties of styrene medium during pipeline transportation under different working conditions are studied. The research results have certain guiding significance for the design and field operation of styrene pipelines in practical projects

Key words: styrene, piping, mathematical model, thermodynamic property, flow
