In closed oil transportation systems, it is necessary to conduct regular pressure relief tests on the low-pressure relief valves. 92. During the operation of the automatically controlled oil transfer station, it is necessary to regularly check the high and low pressure relief valves as well as the heating system for the pipelines, ensuring that they are in good condition; the heating temperature should be maintained within the range of 25–35°C. 93. To ensure the safe and smooth trial operation and commissioning of long-distance pipelines, centralized and unified scheduling and command are necessary. 94. Before the commissioning of long-distance pipelines, various oil transportation equipment, pipeline networks, valves, as well as control, regulating, and protection devices and instruments must undergo inspection and be found to be in good condition. 95. A practical and reliable operation plan must be developed before the long-distance pipeline is put into trial operation and production. Answer: 91. × In closed oil transportation systems, it is necessary to conduct regular pressure relief tests on the high-pressure relief valves. 92. During the operation of the automatically controlled oil transfer station, it is necessary to regularly check the high and low pressure relief valves as well as the heating system for the pipelines, ensuring that they are in good condition; the heating temperature should be maintained within the range of 25–45°C. 93.√ 94.√ 95.× A practical and reliable commissioning plan must be developed before the long-distance pipeline is put into operation.
