<span style="white-space:normal;">综上所述，直埋保温管道在保温性能，初投资，施工条件，维护工作量及日常运行费上均有较大优势。保温直埋管道的设计因本工程空调用热水的更高温度为60℃，更低温度为7℃，因此直埋管道承受的应力不会太大。一般直埋管道材料为20号无缝钢管或Q235管材，在15℃以上的温度下安装时，直埋敷设供热管道（<100℃）不用采取任何措施，按无补偿安装形式将管道直接埋设地下（无固定支座、无补偿器），管道就可达到安全运行。因此对于区域供冷供热（<100℃的水系统）使用无补偿安装形式将是便捷、安全和经济的。无补偿直埋敷设是利用土壤与外套管之间的摩擦力固定管道。管道敷设完覆土前应预热管道，管线上*设补偿器，通常也*设固定支架。为减小工程费用，可在预热的同时进行水压试验。区域供冷供热的管线特点是管内介质温度不高（<100℃），工作压力<1.0MPa，但管线较长，直管段经常长达几百米。土壤摩擦力远大于温度应力，在直管段中间出现“锚固段”，锚固端为危险断面，要应力验算使之满足钢材许用应力。使用无补偿安装形式的直埋敷设供热管道的水平弯头、三通处应力集中。，设计时，应通过应力计算，选择合适压力等级的弯头及三通。一般来说，对空调供回水管道，为保险起见，在选用弯头和三通时可以考虑采用比管道高一个压力等级。</span><br style="white-space:normal;" />
