Abstract: This paper introduces the design and development on laboratory simulation software for constant temperature oil pipeline on the basis of MCGS and VB programming. This software is helpful in design and calculation on the selection of pump and pipeline. The operators can master the normal operation condition,by-pass operation condition,plugging condition,leaking condition of pipeline,also the simulation conditionof pipeline in series and/or parallel operation of stations as well as relative operation condition analysis diagram by means of this simulation software.
