地暖管
地暖管指低温热水地面辐射采暖系统（简称地暖）中用来作为低温热水循环流动载体的一种管材。
管材特点
1.质量轻，易于运输，安装，施工。
2.具有良好的柔韧性，使其铺设时方便经济，生产的管材在施工时可以通过盘卷和弯曲等方法减少管件的使用量，降低施工成本。
3.管材弯曲时，在弯曲的部分的应力可以很快得到松弛，不会出现“回弹”现象，便于施工操作。
4.管内磨擦损失小，此种管的输送流体能力比同管径金属管大30%。
5.脆裂温度低。管材具有优越的耐低温性能，因此在冬季低温的情况下也可以施工，并且在弯曲时管道无需预热。
6.耐化学腐蚀性好，不生锈，使用寿命长。
7.良好的环境适应性。
8.在工作温度为70摄氏度压力为0.4MPa条件下，可安全使用50年以上。
9.管材在生产过程中不添加任何有毒助剂。内壁光滑，不结垢，不滋生细菌，可以安全应用在饮用水输送等领域。
10.抗冲击性能是PVC-U管材的5倍。
11.耐热耐压性好。
12.可以热熔连接和机械连接，可靠、不渗漏。而PE-X只能机械连接。
13.绿色环保产品，可回收再利用。
14.耐高温性好，在适当的压力条件下可使用50年；
15.耐低温霜冻性能好，同时具有优异的抗冲击性，适于冬季施工；
16.良好的抗化学腐蚀性能，使用寿命长；
17.无毒、无味、卫生性能好；
18.重量轻，柔韧性好，可盘管供货；
19.热熔性材料可回收，具有环保效益；
