【摘要】天然气使用量的急剧增加，而管网设施是天然气发展的基本条件之一，也是国家现代化的重要标志，特别是城市燃气管网设施的建设，它是一个城市生存和发展的必要保障和国家重要的基础设施。
天然气管道从天然气供应场所到其使用地方，经过各种各样复杂的地形，管道所处环境千变万化，且天然气中往往含有硫化氢、二氧化碳等酸性气体，它们对天然气管道造成腐蚀威胁，影响天然气管道的平安运行，因此天然气管道在运营中必须实施防腐蚀保护。%The rapid increase of natural gas usage, and network facilities is one of the basic conditions of natural gas development. Also it is the important symbol of modernization of the country, especially the construction of city gas pipe network facilities. It is necessary to the survival and development of a city's security and the national important infrastructure.
Natural gas is transfered from supplier to each user by natural gas pipeline, after all sorts of complex terrain, pipeline environment, and natural gas often contains the acidic gas such as hydrogen sulfide, carbon dioxide. They can corrode gas pipeline, affect the safe operation of gas pipeline.So the natural gas pipeline corrosion protection must be carried out.
