天然气长输管道的防腐与防护措施

Anticorrosion and Protective Measures for Long-distance Natural Gas Pipeline

天然气运输管道在造价方上资金支出较少,有助于工程建设,而且建设安全,可以减少污染物的排放,还有一定的环保性,便于运输且不容易发生损耗,使得天然气能够得到全面的使用。但是运输管道即便是优点突出,然而由于其埋藏方式也还是有一定的缺陷,在气候、微生物以及化学物质等的作用下出现腐蚀,如果处理不及时,可能会造成比较大的经济损害。本文重点讲解了天然气长输管道一旦出现腐蚀穿孔等事件带来的危害,并其讨论了如何进行防腐和防护。

The natural gas transportation pipeline has less capital expenditure on the cost side,which is conducive to the project construction.Moreover,the construction is safe,which can reduce the emission of pollutants.It is also environmentally friendly,easy to transport and not prone to loss,so that the natural gas can be used comprehensively.However,even though the transportation pipeline has outstanding advantages,it still has certain defects due to its burial mode.corrosion occurs under the action of climate,microorganisms and chemical substances.If it is not treated in time,it may cause relatively large economic damage.This paper focuses on the hazards caused by corrosion and perforation of long-distance natural gas pipeline,and discusses how to carry out anti-corrosion and protection.
