1.国内外的应用情况 放射性检漏技术是50年代初开发的。英国于1952年应用钠-24检查水管线成功;于1955年检查油管,一次可达20km以上。苏联于1956年应用溴-82检查煤气管线;1978年检查4条柴油、汽油管线,取得经济效益28 000卢布。法国备有专门试验管线供长期研究;清管型(Pig)检漏仪已在长输管线上定期应用。美国在50年代曾用碘-131检漏;70年代购买了法国的刮塞式检漏方法专利。丹麦销售的检漏仪,一次可检查管线100km,
1. Applications at home and abroad Radioactive leak detection technology was developed in the early 1950s. The United Kingdom in 1952, sodium-24 check the water pipeline success; in 1955 inspection tubing, up to 20km or more. In 1956, the Soviet Union used bromine-82 to inspect the gas pipeline; in 1978, it inspected 4 diesel and gasoline pipelines and obtained economic benefits of 28,000 rubles. France has dedicated test lines for long-term research; pig-type leak detectors have been used regularly on long-distance pipelines. In the 1950s, the United States used iodine -131 for leak detection; in the 1970s, it purchased a French patent for leak-plug leak detection. Danish sales of leak detectors, a pipeline can be checked 100km,
