國內塑料管產品現狀及未來發展如何？pe市政工程管帶你了解。

塑(su)料(liao)(liao)(liao)管具有重量(liang)輕、耐(nai)腐蝕、水流損失小、安裝方(fang)便等特點(dian)，受(shou)到(dao)了管道工程界的青睞，同時因塑(su)料(liao)(liao)(liao)管與傳(chuan)統金屬管相比，其(qi)生產能耗少，環境污染小，日益受(shou)政府和相關行業重視。在國外，塑(su)料(liao)(liao)(liao)管材正(zheng)不(bu)斷替代金屬或其(qi)他傳(chuan)統材料(liao)(liao)(liao)的管材，發展(zhan)十分(fen)迅速。從1980—1990年(nian)的十年(nian)中除(chu)塑(su)料(liao)(liao)(liao)管以外，其(qi)它各種材料(liao)(liao)(liao)的管材增(zeng)(zeng)長率(lv)總(zong)和還不(bu)足2％，但塑(su)料(liao)(liao)(liao)管的增(zeng)(zeng)長率(lv)卻達(da)(da)到(dao)8％以上，近(jin)幾年(nian)已達(da)(da)到(dao)15%左右(you)，產值也大大提(ti)高。

一(yi)、國內生產能力狀(zhuang)況 

        我國自上(shang)(shang)世紀70年(nian)代開始生(sheng)(sheng)產(chan)(chan)(chan)塑(su)料管(guan)(guan)(guan)(guan)，八十(shi)年(nian)代初(chu)開始在工程建設中(zhong)推廣(guang)應用。近二十(shi)年(nian)來，塑(su)料管(guan)(guan)(guan)(guan)得到(dao)了很(hen)大發展(zhan)，不僅在數(shu)量(liang)上(shang)(shang)，而且在品(pin)種(zhong)和(he)規格上(shang)(shang)都得到(dao)很(hen)大的發展(zhan)。現(xian)在，全國塑(su)料管(guan)(guan)(guan)(guan)生(sheng)(sheng)產(chan)(chan)(chan)線約有2000多條，其中(zhong)引進設備約占(zhan)15％，各種(zhong)塑(su)料管(guan)(guan)(guan)(guan)的生(sheng)(sheng)產(chan)(chan)(chan)能力已達165萬噸，實(shi)際產(chan)(chan)(chan)量(liang)為100萬噸左右。其中(zhong)，PVC－U管(guan)(guan)(guan)(guan)50萬噸，占(zhan)50％；PE管(guan)(guan)(guan)(guan)36萬噸，占(zhan)36％。近幾年(nian)，隨著建筑業(ye)成(cheng)為國民經(jing)濟重(zhong)要支柱產(chan)(chan)(chan)業(ye)和(he)住宅產(chan)(chan)(chan)業(ye)的快速發展(zhan)，建筑室內(nei)塑(su)料管(guan)(guan)(guan)(guan)發展(zhan)很(hen)快，現(xian)已成(cheng)為當今投資的熱(re)點(dian)。 

    1、硬(ying)質聚氯(lv)乙烯(xi)管(guan)(guan)（PVC－U）。硬(ying)質聚氯(lv)乙烯(xi)管(guan)(guan)（PVC－U）主要(yao)用(yong)于城(cheng)市(shi)(shi)供(gong)水(shui)、城(cheng)市(shi)(shi)排水(shui)、建(jian)筑排水(shui)和建(jian)筑給水(shui)等輸送管(guan)(guan)道(dao)。目(mu)前，國(guo)(guo)內一些城(cheng)市(shi)(shi)PVC－U建(jian)筑排水(shui)管(guan)(guan)使用(yong)率達到90％以上；在(zai)城(cheng)市(shi)(shi)供(gong)水(shui)管(guan)(guan)道(dao)中(zhong)，已敷設PVC—U管(guan)(guan)道(dao)5000多公里。國(guo)(guo)內有PVC－U管(guan)(guan)生(sheng)產(chan)(chan)企業600多家，年(nian)生(sheng)產(chan)(chan)能(neng)力(li)達到100萬(wan)噸（實際生(sheng)產(chan)(chan)量(liang)約50萬(wan)噸）。PVC－U管(guan)(guan)生(sheng)產(chan)(chan)規模(mo)在(zai)10000噸／年(nian)以上的企業有30余家；規模(mo)在(zai)5000－10000噸／年(nian)的企業有近60家。PVC－U生(sheng)產(chan)(chan)設備基本(ben)上實現了國(guo)(guo)產(chan)(chan)化(hua)。

    2、聚(ju)乙烯(xi)管(guan)（PE）。聚(ju)乙烯(xi)（PE）管(guan)主要用(yong)于城(cheng)市(shi)燃(ran)氣(qi)、城(cheng)市(shi)給水(shui)(shui)、城(cheng)市(shi)排(pai)水(shui)(shui)、建筑(zhu)給水(shui)(shui)等輸送管(guan)道。目前，國內有PE管(guan)生(sheng)(sheng)產(chan)企業近150余家（其中有近100家是生(sheng)(sheng)產(chan)農村給水(shui)(shui)管(guan)和農業用(yong)灌溉管(guan)），年(nian)生(sheng)(sheng)產(chan)能力達(da)到(dao)45萬噸，生(sheng)(sheng)產(chan)規模在5000噸／年(nian)以上的企業有10余家。 

    3、鋁塑(su)復(fu)合管。目前國內(nei)鋁塑(su)復(fu)合管生產(chan)(chan)企(qi)業達到近300家，生產(chan)(chan)線達到300余(yu)條（其中進(jin)口設(she)備占(zhan)10％，國產(chan)(chan)設(she)備占(zhan)90％），搭接焊(han)生產(chan)(chan)線占(zhan)70％，對接焊(han)生產(chan)(chan)線占(zhan)30％，生產(chan)(chan)能(neng)力達到8億(yi)米／年。 

    4、交聯聚(ju)乙烯管。目前國內(nei)交聯聚(ju)乙烯管生產(chan)企業有(you)近100家，生產(chan)線達到100多(duo)條（其中進口生產(chan)線有(you)10余條），生產(chan)能力達到5億米／年。

    5、無規共聚聚丙(bing)烯管（PP－R）。國(guo)產(chan)(chan)(chan)(chan)的(de)共聚PP原料在(zai)(zai)性(xing)能(neng)上與國(guo)外(wai)名牌PP－R管專用料相(xiang)比，在(zai)(zai)性(xing)能(neng)上尚有(you)一(yi)定差距。因(yin)此，目前國(guo)內生產(chan)(chan)(chan)(chan)PP－R管的(de)原料大部分是從國(guo)外(wai)進口。目前國(guo)內PP－R管生產(chan)(chan)(chan)(chan)企業有(you)近(jin)100家，生產(chan)(chan)(chan)(chan)線有(you)近(jin)120條（其中進口設備有(you)10余(yu)條），生產(chan)(chan)(chan)(chan)能(neng)力(li)達到5億米(mi)／年(nian)。

二、存在問題 

    1、原(yuan)材(cai)料(liao)品種少，質(zhi)量(liang)不穩定(ding)，與國(guo)外名牌專(zhuan)用料(liao)存在一定(ding)差距，導致一些原(yuan)料(liao)依靠進口。 

    2、企業生(sheng)產(chan)規模普遍較小，達不到(dao)經(jing)濟(ji)生(sheng)產(chan)規模，不利(li)于產(chan)品質(zhi)量(liang)提高和價格降低。 

    3、管件的品種少(shao)，規(gui)格不全(quan)，不能(neng)滿足(zu)工程需要。 

    4、產品標準、設計施工(gong)規(gui)范滯(zhi)后，工(gong)程技術人員缺(que)少專業培訓(xun)。 

    5、市場缺乏(fa)規范(fan)化管理，項目(mu)建設盲目(mu)，缺乏(fa)統一規劃，導致一些地區(qu)生(sheng)產(chan)能力過剩，生(sheng)產(chan)設備開工率(lv)嚴重不足(zu)。再加(jia)上質量監督管理力度不夠，假冒偽劣產(chan)品充斥市場。
