热力管道用直埋聚氨酯保温管特点

发布日期:2019-06-20 作者: 点击:

聚氨酯保温管上海11选5在结构上具有下列特点:1、采用固定在内工作钢管上的流动支架和外套管内壁摩擦,保温材料跟随工作钢管一起活动,不会出现保温材料的机械磨损、粉化。2、外套钢管强度高、密封性能好,可有效地防水、抗渗。3、外套钢管的外壁采用优质防腐处理,使外套钢管的防腐层寿命在20年以上。4、工作钢管的保温层选用优质保温材料,保温效果好。5、工作钢管保温层与外套钢管之间留有10~20mm左右的间隙,既可直到进一步保温的作用。又是直埋管道极为通畅的排潮通道,使排潮管真正起到及时排潮的作用,同时起到信号管的作用;或将其抽成低真空,可更有效地保温并降低外套管内壁腐蚀。
