Abstract: For almost all the simulation software for multi-products oil pipeline, the lane data of pipeline are necessary. However, the number of data from regarding pipeline companies is tremendous, which results in slow speed of software. So, the users of software often have to pre-handle the original data to decrease the scale of them. The software for data filtering can help them out of tedious and time-consuming job. In this paper, the author provides a case to apply this software to Southwest Products Oil Pipeline. The application result shows that the human error is basically low to zero level in data filtering, and the influence to the hydraulic calculating accuracy of the pipeline is within the allowable scope of software, which is practical.
