The designing and calculation of insulating layer thickness of the directly buried hot-water heat-supply fiber reinforced plastics pipes

根据热力学理论及采暖设计规范,提出了直埋热水供热玻璃钢管道的计算方法,并对各个参数的确定提出了要求。结合工程实例,列举了计算过程,计算结果表明,热水供热玻璃钢管道与普通供热钢管对比综合效益好。本文为玻璃钢聚氨酯复合保温管的研发和推广应用提供理论依据。

According to thermodynamics theory and design code for heating, the author puts forward calculation methods of the directly buried hot-water heat-supply fiber reinforced plastics （FRP） pipe and the requirements when confirming every parameter. Combined with project cases, calculation process is listed. The calculation result shows that compared with common heating pipes, the overall benefit of hot-water heat-supply FRP is bigger. This paper provides theoretical foundation on the research and promotion of FRP polyurethane compound insulation pipes.
