PE给水管都在哪些地方出现

文章出处:本站责任编辑:Admin人气:发表时间:2017/11/23 10:05:03【
 1、城市自来水管网系统,这个是不容置疑的,现在城市自来水用的80%以上都是PE给水管。
 
2、城乡饮用水管道,这个和第一点有点差不多。
 
3、化工、化纤、食品、林业、印染、制药、轻工、造纸、冶金等工业的料液输送管道,这一点的话相对来说占比要小一点。
 
4、农用灌溉管道,很多灌溉用管现在都改用PE给水管了,耐用。
 
5、邮电通讯线路、电力电线保护套管,使用在这个用途的都是土豪,因为PE给水管的造价还是比较高的。
 
6、矿山砂浆输送管道,现在很多矿区都开始使用PE给水管了。
