Russia must first pump "technical" gas into the pipeline, raising the pressure to the point where commercial deliveries can begin.
俄罗斯必须首先向该天然气管道注入“技术性”天然气，使管内压力升到一定水平，商用输气才可以开始。No lubrication air compressor can only do gas transmission does not include any oil content, can't do it no water.
无润滑空压机只能做到输气不含油，不能做到不含水。European nations worry about their dependency on Russian gas, particularly in the light of previous pipeline closures.
欧洲国家因其对俄罗斯天然气的依赖而忧心忡忡，尤其是在俄罗斯数次关闭输气管道之后。This provides for the development of genuine spot markets, since the movement of gas is no longer limited by how far pipelines extend.
这种流程为建立真正的天然气现货市场创造了条件，因为天然气的运输不再受限于输气管道的分布了。Usually, the leakage of natural gas transport pipelines account for 10% of the total amount of transported gas.
通常天然气管道的泄漏量一般大约要占输气总量的10%。Per the Zetas, gas lines are a very real danger, not to be ignored.
根据齐塔人的说法，输气管道是一个很大的威胁，不要忽视。Gas turbines are also used for gas transmission and injection.
燃气轮机也被用来输气和注气。The scenario on replacing the leaked gas pipeline and its implementation for north-loop line located at Sichuan is introduced.
介绍了四川北半环输气干线停输更换漏气管段方案实施过程及步骤。The experimental result shows, the condensor in the environmental of pressure can be used in the detectation of the pipelines leak.
输气管道泄漏点检测实验结果表明，压力场环境下的声纳传感器可以应用于输气管道泄漏检测。
