摘要
介绍直埋蒸汽管道复合保温层的塑(或玻璃钢)套钢结构、钢套钢结构。以钢套钢结构的直埋蒸汽管道(设计温度为300℃,设计压力为1.6 MPa,公称直径400 mm的工作管)为例,进行复合保温材料的厚度计算。
The fiberglass reinforced plastic （FRP） jacket structure and steel jacket structure of composite insulation layer of directly buried steam pipe are introduced. Taking directly buried steam pipe with steel jacket （ under design temperature of 300 ℃, design pressure of 1.6 MPa and nominal diameter of 400 mm） for example, the thickness of composite insula- tion material is calculated.
