摘　　要：根据温度补偿器的工作原理及热水直埋管道的敷设方式,探讨了直埋玻璃钢/聚氨酯保温管温度补偿的设计方法。工程实例计算结果表明,玻璃钢/聚氨酯保温管与传统钢制热力管道相比,可以不设或少设温度补偿器。According to the principles of temperature compensator and lay down method ot heat-water cllreet layoown pipe, the design of temperature compensational of direct laydown glass fiber reinforced plastics （ FRP ） / polyurethane heat pipes was discussed.Compared with traditional steel heat-water pipe in the engineering projects, FRP / polyurethane pipes need not or less temperature compensator through calculate results of project examples.
