Cold and hot water heat preservation pipe

一种冷热水保温管

Abstract

The utility model discloses a cold and hot water heat preservation pipe. The cold and hot water heat preservation pipe is characterized in that a heat preservation layer, a liner pipe and an outer sleeve are sequentially arranged outside a cold and hot water steel pipe, the outer sleeve is an HDPE plastic pipe, the liner pipe is a steel thin-walled pipe which is manufactured in the outer sleeve in a liner mode, and the heat preservation layer is a polyurethane foam layer arranged between the cold and hot water steel pipe and the liner pipe in a filled mode. Compared with the prior art, the cold and hot water heat preservation pipe is good in tenacity and high in shock resistance, the strength, the rigidity, the waterproofness and the corrosion resistance of the heat preservation pipe are improved, and the heat preservation pipe is simple in structure, light in weight, good in heat preservation effect, low in manufacturing cost and convenient to construct, and effectively reduces heat loss of a pipe network.
本实用新型公开了一种冷热水保温管,其特点是冷热水钢管外依次设有保温层、内衬管和外套管;所述外套管为HDPE塑料管;所述内衬管为衬制在外套管内的钢制薄壁管;所述保温层为填充在冷热水钢管与内衬管之间的聚氨酯泡沫层。本实用新型与现有技术相比具有良好的韧性和抗冲击能力,提高了保温管道的强度、刚度以及防水和耐腐蚀性能,而且结构简单,重量轻,保温效果好,制造成本低,施工方便,有效减少管网的热损。
