　　使(shi)用外3PE內IPN8710防腐鋼管(guan)結(jie)構特點:

　　(1)具有優良(liang)的抗腐蝕性能不要陰極防(fang)腐保護及其它防(fang)腐措施，不會對水和(he)其它介質產生二(er)次污染(ran)。產品使用壽命長。

　　(2)重量(liang)輕管(guan)道(dao)重量(liang)僅占同規(gui)格(ge)、同長度球墨鑄鐵管(guan)的(de)1:4，水泥管(guan)道(dao)的(de)1:10。運(yun)輸(shu)裝(zhuang)卸方(fang)便(bian)，易于安裝(zhuang)。

　　(3)單根(gen)管(guan)(guan)(guan)道長(chang)度長(chang)減(jian)少管(guan)(guan)(guan)線(xian)(xian)接頭，加速安裝(zhuang)速度，提高整條(tiao)管(guan)(guan)(guan)線(xian)(xian)質(zhi)量(liang)。 IPN8710飲水防(fang)腐鋼管(guan)(guan)(guan)鋼材表(biao)面除銹后應在16小(xiao)時內(nei)，在潮(chao)濕(shi)區和沿海地區應在8小(xiao)時內(nei)涂(tu)刷(shua)底漆，否則發生(sheng)(sheng)二(er)次生(sheng)(sheng)銹，則須用鋼絲刷(shua)處(chu)理。

　　(4)管(guan)壁(bi)(bi)內壁(bi)(bi)光滑(hua)減少流(liu)(liu)阻(zu)、提(ti)高(gao)流(liu)(liu)速(su)、降低(di)能耗。用(yong)(yong)較小口(kou)徑的(de)管(guan)道輸送同等流(liu)(liu)量的(de)流(liu)(liu)體，與同規(gui)格鋼管(guan)相比可提(ti)高(gao)流(liu)(liu)量的(de)10%左右；不結(jie)垢，長期使用(yong)(yong)不降低(di)流(liu)(liu)速(su)。擾和重蝕環境中電纜的(de)防護都有較好效果。
