摘要
介绍了国内外数种直埋式高温保温管的保温材料性能及结构特点,指出我国高温直埋管道技术近年进展很快,接近世界先进水平,但深入的基础研究尚待开展。
The article introduces the performances of insulation material and the structure characteristics of a number of domestic and foreign directly buried insu- lation pipes and points that,the development of domestic directly buried pipe tech- nique is quite rapid in the latest years and gets to access foreign advanced level,but it is necessary to develop the basic research deeply.
