Abstract: Pipeline valve station was the important facilities to ensure the safe operation of long distance pipeline. It can reduce oil leakage loss and environmental pollution. There are several problems in the design of pipeline valve station in China. It should be unified and specified at the standard level, such as the lack of flexibility in valve site selection and spacing, the difference in valve station crossing and over-crossing , the design of check valve, and the poor reliability of valve station in remote areas. The pipeline valve station design standards of USA, Russia and Canada were selected, and the important technical differences between domestic and foreign valve station design standards were studied, and the practical experience of foreign pipeline valve station design and operation management was introduced, such as the site selection principle of reducing oil leakage risk and economic loss, 10% and 25% distance adjustment for oil and gas pipeline valve station in special area, the RTU valve station setting principle, the recommended practice of river crossing and over-crossing valve station, valve station power demand to determine the power supply mode, preferred to use above-ground valve station, etc. Finally, some suggestions are put forward to improve the design standard of pipeline valve station in China.
