摘要
针对硫酸盐还原菌(SRB)对燃气管道的腐蚀问题,介绍了硫酸盐还原菌对管道的腐蚀机理及主要影响因素。结合现场实际案例,分析了硫酸盐还原菌(SRB)的腐蚀特征及采取的防护措施。结果表明:通过定期清管、加注杀菌剂、保持合理流速、采用内涂层是有效防控硫酸盐还原菌腐蚀的主要措施。研究结论可为城镇燃气管道的腐蚀防护提供借鉴。
The corrosion mechanism of sulfate-reducing bacteria(SRB)on pipeline and its main influencing factors were introduced.The corrosion characteristics of sulfate-reducing bacteria(SRB)and the protective measures were analyzed.The results showed that regular pigging,adding fungicide,maintaining reasonable flow rate and using inner coating were the main measures to effectively prevent and control sulfate reducing bacteria corrosion.The conclusion can provide reference for the corrosion protection of urban gas pipelines.
