苏联研制了一系列检测天然气管道漏气的激光仪,这种激光仪安装在Mi-8型直升飞机上,现场试验时,它可发现从输气管道微小孔隙中泄露的天然气。直升飞机离地面60m,飞行速度120km/h。苏联北部产气区,正在试验一台称作“Lskatel”的激光仪,它的性能与上述激光仪相类似,但这种仪器是安装在卡车上,激光束可对准整个管道追踪泄漏点。苏联还研制一种类似英国天然气公司的智能清管器的磁场检漏仪,可从管道内部发现缺 The Soviet Union has developed a series of lasers to detect gas leaks in natural gas pipelines installed on Mi-8 helicopters. During field tests, it can detect natural gas leaked from tiny pores in gas pipelines. Helicopters off the ground 60m, flight speed 120km / h. In the northern Soviet gas region, a laser called “Lskatel” is being tested and its performance is similar to that of the laser described above, but the instrument is mounted on a truck and the laser beam can be aimed at the entire pipe to track leaks. The Soviet Union also developed a magnetic leak detector similar to the British gas company’s smart pig, which can be found inside the pipeline from the lack of
