埋地钢质管道保温管的使用寿命及结构方式

2019-06-10 14:25:30

管道腐蚀是一种普遍存在的问题,据介绍全世界因管线腐蚀而造成的经济损失已超过500亿美元;介质在管道中输送,将会有很大的热量损失,采用保温措施后可以减少90%的热损失,其经济效益十分显著。随着社会经济的不断发展,油田内外部产能建设增加,埋地管道工作量也随之大幅提升,管道防腐保温工程重要性逐渐凸显,管线输送介质温度一般不超过120℃。本文通过对埋地管道防腐保温的结构、选用材料、厚度、性能、防护、热损失和防水性等方面的标准规定进行梳理和确认,分析和研究埋地管道防腐保温的技术要点和改善措施,总结过去防腐保温的经验,提高管道防腐保温工程质量,以节约能源,延长管道使用寿命,确保管道防腐保温效果有所提升。
