近10年,我国油气管道建设突飞猛进,截至2013年10月底,我国现有油气长输管道10.6万公里,比国家高速公路总里程多1万公里。管道输送已成为油气资源的最主要输送方式,是我国能源供应的大动脉。油气输送管道长时间服役后,会因外部干扰、腐蚀、管材和施工质量等原因发生失效事故,导致火灾、爆炸、中毒等事件,造成重大经济损失、人员伤亡和环境污染。如何保证油气管道的安全运行,已引起我国政府和管道运营企
In the past 10 years, the construction of oil and gas pipelines in our country has progressed by leaps and bounds. By the end of October 2013, China had 106,000 km of long-distance oil and gas pipelines and 10,000 km more than the total national highway mileage. Pipeline transportation has become the most important transportation mode of oil and gas resources, which is the artery of China’s energy supply. After a long period of service, the oil and gas pipeline will fail due to external interference, corrosion, pipe and construction quality, causing fire, explosion and poisoning, resulting in serious economic losses, casualties and environmental pollution. How to ensure the safe operation of oil and gas pipelines has caused our government and pipeline operators
