天然气输送管道的腐蚀与保护探讨

Discussion on Corrosion and Protection of Natural Gas Pipeline

天然气是我国社会发展和经济建设的重要能源,尤其其气体的状态以及物理化学特性,对运输的方式具有很高的要求。目前,管道运输是使用最广泛、最主要的运输方式。在长期、长距离的天然气管道运输的过程中,如果出现腐蚀的情况,很容是造成天然气的泄漏,造成资源的浪费和环境的污染等,严重的情况会导致天然气发生爆炸,危害到人们的生命和财产安全。本文对天然气输送管道的腐蚀原因进行分析,并且提出相应的保护措施。

Natural gas is an important energy source for China＇s social development and economic construction, ln particular, the state of gas and its physieo-chemical characteristics have very high requirements on the mode of transportation. At present, pipeline transport is the most widely used and the most important mode of transport. In the long-term and long-distance natural gas pipeline transportation, if corrosion occurs, it is very easy to cause natural gas leakage, resulting in resource wastage and environmental pollution. In severe cases, natural gas will explode and endanger people＇s Life and property safety. This paper analyzes the corrosion causes of natural gas pipeline, and puts forward corresponding protection measures.
