摘　　要：对不同介质温度条件下有空气保温层的“钢套钢”蒸汽直埋管保温结构厚度进行了数值计算,并将计算结果与无空气保温层的保温结构厚度进行了比较。计算结果若用于实际工程,可在确保保温效果的前提下,减小保温层厚度和外套钢管的使用量,以达到减少材料的使用、节约投资的目的。This paper calculates the thermal insulation thickness of the ＂steal sheated steal＂ directly buried steam pipe with air thermal insulation layer under the condition of different temperatures, and compares it with the system without air thermal insulation layer. This calculation can be applied to practical projects for thinning the thermal insulation thickness and reducing the use of coat steel pipe, contributing to the purpose of reducing materials and investment.
