1、PE管的(de)用途：

　　PE管與傳統(tong)的(de)(de)金屬(shu)管和(he)其它塑料管相比,具有(you)密度低(di)、強度與質(zhi)量(liang)比高、脆給溫度化低(di)、韌性(xing)好、耐腐蝕絕緣性(xing)能好、易(yi)著色(se)、易(yi)于施工和(he)安裝等(deng)特點、廣(guang)泛應用(yong)于市政和(he)建筑(zhu)給排水、燃氣(qi)、供熱采暖、電線(xian)電纜穿(chuan)線(xian)、農用(yong)節水灌(guan)溉(gai)和(he)工業排污、礦(kuang)山礦(kuang)物輸送等(deng)領(ling)(ling)域(yu)。與鋼管相比，成本(ben)可(ke)降(jiang)12%左右，工作壽命(ming)長，可(ke)達成50a(鋼管一(yi)般為20a),而且維護(hu)費用(yong)低(di)。在(zai)國(guo)外的(de)(de)發達國(guo)家(jia)和(he)地(di)區，PE管是城際埋地(di)燃氣(qi)管道中的(de)(de)占有(you)量(liang)已達90%以上，在(zai)供水管所占市場份額達60%，并且國(guo)外在(zai)PE管材(cai)方面(mian)憶經建立起了非常成熟的(de)(de)標準的(de)(de)施工規(gui)范(fan)。在(zai)我國(guo)，鍍鋅管逐步被禁(jin)用(yong)后，PE管在(zai)建筑(zhu)供水等(deng)領(ling)(ling)域(yu)很有(you)競爭優勢，在(zai)燃氣(qi)、工業供排水、通訊(xun)、農業灌(guan)溉(gai)等(deng)領(ling)(ling)域(yu)PE管材(cai)也呈迅速(su)增(zeng)長的(de)(de)態勢，但(dan)有(you)些領(ling)(ling)域(yu)的(de)(de)管材(cai)標準和(he)規(gui)范(fan)還未(wei)跟上，在(zai)一(yi)定(ding)程度上影響了PE管材(cai)的(de)(de)應用(yong)和(he)發展。

　　2、PE管的分(fen)類方法：

　　PE管(guan)(guan)(guan)(guan)(guan)(guan)的分類(lei)方法很多，種類(lei)也很多。按用(yong)(yong)途分，可(ke)分為(wei)建(jian)筑和(he)市政(zheng)給排水管(guan)(guan)(guan)(guan)(guan)(guan)室外燃(ran)氣管(guan)(guan)(guan)(guan)(guan)(guan)、農用(yong)(yong)灌溉管(guan)(guan)(guan)(guan)(guan)(guan)、穿(chuan)線管(guan)(guan)(guan)(guan)(guan)(guan)(電(dian)線、電(dian)纜及光纜)、排污(wu)管(guan)(guan)(guan)(guan)(guan)(guan)等。表1列出了幾種常見用(yong)(yong)途的PE管(guan)(guan)(guan)(guan)(guan)(guan)材(cai)(cai)。按管(guan)(guan)(guan)(guan)(guan)(guan)材(cai)(cai)品(pin)質和(he)結(jie)構分，PE管(guan)(guan)(guan)(guan)(guan)(guan)材(cai)(cai)可(ke)分為(wei)普通(tong)PE管(guan)(guan)(guan)(guan)(guan)(guan)、鋁塑復合(he)管(guan)(guan)(guan)(guan)(guan)(guan)、鋼塑復合(he)管(guan)(guan)(guan)(guan)(guan)(guan)、鋼塑復合(he)管(guan)(guan)(guan)(guan)(guan)(guan)、加筋(筋為(wei)金屬絲，網等)管(guan)(guan)(guan)(guan)(guan)(guan)單(dan)/雙(shuang)壁波紋管(guan)(guan)(guan)(guan)(guan)(guan)、螺旋管(guan)(guan)(guan)(guan)(guan)(guan)、光纜用(yong)(yong)硅芯管(guan)(guan)(guan)(guan)(guan)(guan)等。按原材(cai)(cai)料密(mi)度(du)(du)分，可(ke)分為(wei)高密(mi)度(du)(du)管(guan)(guan)(guan)(guan)(guan)(guan)、低密(mi)度(du)(du)管(guan)(guan)(guan)(guan)(guan)(guan)以(yi)及中(zhong)(zhong)密(mi)度(du)(du)管(guan)(guan)(guan)(guan)(guan)(guan)(中(zhong)(zhong)密(mi)度(du)(du)管(guan)(guan)(guan)(guan)(guan)(guan)因用(yong)(yong)途與高密(mi)度(du)(du)管(guan)(guan)(guan)(guan)(guan)(guan)相同，常視為(wei)高密(mi)度(du)(du)管(guan)(guan)(guan)(guan)(guan)(guan)的一(yi)種)。
