摘要
城镇燃气管道是燃气运输的必备手段,但是由于原有燃气管道的老化、腐蚀、运行管理不善等原因,这就给管道的运行带来了极大的安全隐患。文章浅析了造成城镇燃气管道内外面腐蚀的原因,并介绍了三种城镇燃气管道非开挖修复技术——管道穿插技术、胀管法和CIPP紫外线光固化法。
Urban gas pipeline is an indispensable means of gas transportation, but because of the aging of the original gas pipeline, corrosion, poor management and other reasons, it has brought great security risks to the pipeline operation. This paper analyzes the causes of urban gas pipeline inside and outside surface corrosion, and introduces three kinds of urban gas pipeline trenchless repair technology - pipeline intercalation technology, expansion tube method and CIPP ultraviolet light curing method.
