Software tool for calculating top corrosion of moisture pipeline

A software tool for calculating the top corrosion of a moisture pipeline comprises a pipeline pressure and temperature analysis module which calculates the pressure and temperature of each section of pipeline according to pipeline pressure drop and temperature drop mechanism models; the natural gas physical property analysis module is used for calculating physical property parameters such as molar mass, density/relative density, critical pressure and temperature, compression coefficient, specific heat capacity and diffusion coefficient of natural gas according to a physical formula; the water dew point analysis function module is used for calculating the water dew point temperature of the medium in the pipeline; the pipe top condensation analysis module is used for calculating the condensation rate of the pipe top and the falling form of condensed water; and the electrochemical corrosion analysis module is used for calculating the top corrosion rate of the pipeline. The method has the beneficial effects that
