摘要
介绍直埋蒸汽管常规保温结构,提出选用气凝胶毡和耐高温离心玻璃棉保温层的优化保温结构。结合工程实例,对采用优化保温结构的直埋蒸汽管道单位管长温降进行实测计算。
The conventional insulation structure of directly buried steam pipeline is introduced,and the optimized insulation structure of aerogel felt and high- temperature resistant centrifugal glass cotton insulation layer is proposed. Combined with an engineering example ,the unit length temperature drop of the directly buried steam pipeline with the optimized insulation structure is measured and calculated.
