Pressure-Velocity Model for In-Pipe MFL Detector in Gas Pipeline

Abstract:

The accuracy of the data detection can be affected by speed of in-pipeline MFL detector during non-destructive testing of gas pipeline. So speed regulation of in-pipeline MFL detector is researched in this paper. Speed regulation of in-pipeline MFL detector can be seen as change of speed under different steady state. In-pipeline MFL detector and up-down stream gas are regarded as a particle. According to principles of fluid mechanics, the relationship of pressure of pipeline and speed of in-pipeline detector is analyzed and pressure-speed model of in-pipeline detector is built. The speed of in-pipeline detector is calculated under different steady state based on pressure-speed model for the purpose of speed adjustment. The results of simulation in the Second West-East natural gas pipeline show that the speed of in-pipeline detector can be accurately calculated and effectively adjusted.
