6个答案
需要。保温作用：一、保温 ： 热水管保温防止水温度流失过快， 冷水管保温可以防止走冷水的时候管外壁结露、冷凝水形成 。二、是隔音降噪： 可以极大地降低水流的声音 ，减少对周围环境影响。三、保护： 可以减缓管道的外表老化；防止热水管道对老人，幼儿的烫伤。
用聚氨酯直埋保温管（埋地用的）外套管：高密度聚乙*管壳；无缝管是一种具有中空截面、周边没有接缝的长条钢材。全世界生产无缝管的共计有110多个*的1850多个公司下的5100多个生产厂，其中生产石油管的有44个*的170多个公司下的260多个厂。按生产方法不同可分为热轧管、冷轧管、冷拔管、挤压管等。
必须要的。1、保温 热水管保温防止水温度流失过快 冷水管保温可以防止 走冷水的时候 管外壁冷凝水2、隔音降噪 可以极大地 降低水流的声音3、也是一层保护 可以减缓 管道的外表 老化
其实管里存不下多少水，无所谓了。如果在室外的话，那就尽量设计的短一些吧暖气管就不用考虑保温，在墙里也是散热，一般也用不到保温，反正在家里都是散热，考虑用聚氨酯包一层吧。如果是洗澡水管
像25*3.5壁厚的水压式20兆帕，在这个范围内水管都不会有问题。冬天会爆管是因为水管里的水处于停止状态，结成冰，时间一长，水压增大，PPR分子不均匀。水管上面处于薄弱的那一点就爆裂。解决办法就是*的那一段水哗发糕菏蕹孤革酞宫喀管套一层保温管，或者把水龙头开一点，要水流通。压力就可以得到释放。
