風(feng)管(guan)(guan)(guan)(guan)就(jiu)是用于空氣輸送和分布的管(guan)(guan)(guan)(guan)道。在(zai)化工，食品等(deng)行業，對通風(feng)管(guan)(guan)(guan)(guan)道系統的要求比較高，之(zhi)前的金(jin)屬(shu)風(feng)管(guan)(guan)(guan)(guan)，在(zai)經濟功效(xiao)比上(shang)遠(yuan)遠(yuan)落后(hou)于塑料風(feng)管(guan)(guan)(guan)(guan)。塑料風(feng)管(guan)(guan)(guan)(guan)中以PPH、PP風(feng)管(guan)(guan)(guan)(guan)所占比例大(da)。

PP圓形/方形風管配件特點：

1、耐化(hua)學性：在所有聚丙烯(xi)管(guan)材中，實驗證明具有.強(qiang)的耐化(hua)學性能。 

2、壽 命 長：具有更長的(de)使(shi)用壽命和更高的(de)系統安全性(xing)。

3、沖擊強(qiang)(qiang)度：與傳(chuan)統的相比(bi)較，具有顯著的低溫(wen)抗(kang)沖擊強(qiang)(qiang)度。 

4、耐溫(wen)：根(gen)據實際(ji)應(ying)用(yong)(yong)情況，適(shi)用(yong)(yong)的溫(wen)度(du)(du)范(fan)圍(wei)從-20度(du)(du)到100度(du)(du)。 

5、耐壓：在(zai)所有(you)應用(yong)于(yu)管(guan)路系統的(de)聚(ju)丙烯(xi)材料中，具有(you).高的(de)耐壓性能(neng)（MRS10）。 

6、高 性(xing) 能(neng)：性(xing)能(neng)優(you)異、使用靈活的焊接設(she)備以及專業的隊伍不(bu)僅(jin)可以保證。

7、PP管系統(tong)的焊接安裝質量，還(huan)可以(yi)根據需要為客戶提供非標產品(pin)的定制(zhi)加工。 

PP圓形/方形風管風(feng)(feng)(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan)，是(shi)(shi)用于空氣輸送和(he)分布的管(guan)(guan)(guan)(guan)(guan)道系統。有復合風(feng)(feng)(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan)和(he)無機風(feng)(feng)(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan)兩種。復合風(feng)(feng)(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan)以Durkduct風(feng)(feng)(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan)為代(dai)表(biao)。可按截面形(xing)(xing)狀(zhuang)(zhuang)和(he)材質分類。風(feng)(feng)(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan)制(zhi)(zhi)作(zuo)(zuo)不銹鋼風(feng)(feng)(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan)制(zhi)(zhi)作(zuo)(zuo)是(shi)(shi)在咬口縫(feng)、鉚(liu)釘縫(feng)、法蘭翻(fan)邊四角等縫(feng)隙處涂(tu)上密封(feng)膠（如中性玻璃膠）。涂(tu)密封(feng)膠前應清(qing)除表(biao)面塵土和(he)油污。按截面形(xing)(xing)狀(zhuang)(zhuang)，風(feng)(feng)(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan)可分為圓(yuan)(yuan)形(xing)(xing)風(feng)(feng)(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan)，矩形(xing)(xing)風(feng)(feng)(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan)，扁圓(yuan)(yuan)風(feng)(feng)(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan)等多種，其(qi)中圓(yuan)(yuan)形(xing)(xing)風(feng)(feng)(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan)阻力小但高(gao)(gao)度尺(chi)寸大，制(zhi)(zhi)作(zuo)(zuo)復雜。所以應用以矩形(xing)(xing)風(feng)(feng)(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan)為主。按材質，風(feng)(feng)(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan)可分為金(jin)屬風(feng)(feng)(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan)，復合風(feng)(feng)(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan)，高(gao)(gao)分子風(feng)(feng)(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan)。
