HDPE管與PVC－U管、PP－R管、鋁塑復(fù)合管的價(jià)格比較：

室外給水管道主要有球墨鑄鐵管、鍍鋅鋼管、PVC-U給水管、HDPE管等，HDPE給水管道之所以能取得如此快速的發(fā)展和應(yīng)用，還在于HDPE管道具有經(jīng)濟(jì)實(shí)用的特點(diǎn)，下面以一工程實(shí)例說明。

例如一個(gè)項(xiàng)目，室外供水管道需從500m外的市政給水管道引入，引入管管徑為DN400.至建筑紅線處，分兩路進(jìn)水，管徑為DN300，室外環(huán)管總長約800米。原設(shè)計(jì)為球墨鑄鐵管。按照公司規(guī)定，需要對(duì)管
