LNG管道保冷材料及施工

摘要

Combing with the current situation of cold insulation of LNG pipelines all over the world,cellular glass, polyisocyanurate foam as well as flexible elastomeric foam were introduced.The cold insulation structures and construction processes of LNG pipelines were also elaborated for the relevant materials,respectively.%结合国内外液化天然气（LNG）管道保冷现状，介绍了以泡沫玻璃、聚异氰脲酸酯泡沫为代表的硬质保冷材料和以发泡弹性体为代表的柔性保冷材料，并分别对相应的LNG管道保冷结构及施工工艺进行了阐述说明。
