Abstract: The surge tests made are introduced for some oil pipelines in China, the performances of regulating valve system used in pipelines are basically described, and the surge control tests are analyzed in detail. It is emphasized that the regulating valve system must response sensitively and has a high closed speed. The operation mode of start-up and shut down of a pump are the same, which would produced a surge wave, while regulating valves go on the control in the wave source. It is vital for a regulating system to have the capacity of sensitivity, reliability and stability in the closed oil transportation, which is a fundamental mea- sures on optimizing and safetying operation. The regulating system should both stably regulate and control surge with fast respondency, and its regulating response is directly proportional to variational ratio of pressure. It is pointed out that the surge control mode and protection measures used in existing pipelines in China are: ① regulating valve control; ② protection with low pressure relief valve; ③ automatic shut down pumps. As for the control of the negative surge wave, quick opening regulating valves can be used, while the positive surge wave, low pressure relief valves can be used in pressure relieving besides sensitive regulating valve system, in order to reduce surge pressure.
