PP風管是用(yong)于(yu)空氣輸送和分布的管(guan)(guan)(guan)(guan)(guan)(guan)(guan)(guan)道(dao)系統。有復(fu)(fu)合風(feng)(feng)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)(guan)和無機風(feng)(feng)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)(guan)兩(liang)種。復(fu)(fu)合風(feng)(feng)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)(guan)以(yi)Durkduct風(feng)(feng)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)(guan)為(wei)代表。可按截(jie)(jie)面(mian)(mian)形(xing)(xing)(xing)狀(zhuang)和材質分類。風(feng)(feng)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)(guan)制作(zuo)(zuo)不銹(xiu)鋼風(feng)(feng)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)(guan)制作(zuo)(zuo)是在咬口(kou)縫、鉚釘縫、法蘭(lan)翻邊四(si)角等縫隙(xi)處涂(tu)上密(mi)封(feng)膠(jiao)(jiao)(jiao)（如(ru)中性玻璃膠(jiao)(jiao)(jiao)）。涂(tu)密(mi)封(feng)膠(jiao)(jiao)(jiao)前應清除表面(mian)(mian)塵土和油污。按截(jie)(jie)面(mian)(mian)形(xing)(xing)(xing)狀(zhuang)，風(feng)(feng)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)(guan)可分為(wei)圓形(xing)(xing)(xing)風(feng)(feng)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)(guan)，矩形(xing)(xing)(xing)風(feng)(feng)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)(guan)，扁圓風(feng)(feng)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)(guan)等多(duo)種，其中圓形(xing)(xing)(xing)風(feng)(feng)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)(guan)阻力(li)小(xiao)但高(gao)度尺寸(cun)大，制作(zuo)(zuo)復(fu)(fu)雜。所以(yi)應用(yong)以(yi)矩形(xing)(xing)(xing)風(feng)(feng)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)(guan)為(wei)主。按材質，風(feng)(feng)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)(guan)可分為(wei)金屬風(feng)(feng)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)(guan)，復(fu)(fu)合風(feng)(feng)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)(guan)，高(gao)分子風(feng)(feng)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)(guan)。

PP風管用(yong)在化工(gong)企業用(yong)來排風(feng)的(de)管道，采用(yong)PP材質其有(you)腐蝕(shi)性。PP通(tong)風(feng)管有(you)圓(yuan)形和方(fang)形兩種(zhong)，以圓(yuan)型較多，顏色有(you)米黃色（微機(ji)灰）和白色，使用(yong)方(fang)便(bian)低，一(yi)般(ban)連接采用(yong)焊條承插。

PP通(tong)風管特點

1、不(bu)銹蝕：PP管可在(zai)(zai)很大的溫度(du)范圍內承受PH值，范圍在(zai)(zai)1～14的高濃度(du)的酸和堿的腐蝕。

2、損、不結(jie)(jie)垢：PP管(guan)及(ji)管(guan)件內壁均勻光滑，流動阻力(li)小并(bing)且不結(jie)(jie)垢。

3、減小振動(dong)和噪聲(sheng)：PP管具有優良的隔聲(sheng)性能，可減少(shao)由液體流動(dong)引(yin)起的振動(dong)和噪聲(sheng)。

4、防凍(dong)裂：PP材料彈性(xing)優良使得管材和管件截面可隨(sui)著凍(dong)脹(zhang)的(de)液體一起膨脹(zhang)而不會(hui)脹(zhang)裂。

5、防結露，熱損失少：PP材料為不良熱導體，可減少結露現象并減少熱損少。

6、安裝簡單：PP管(guan)重量輕，安裝操(cao)作方便，并且具有(you)可焊(han)性。

PP通風管(guan)從擠(ji)出(chu)機放出(chu)來的(de)(de)熔融(rong)原料(liao)慢(man)慢(man)變成環狀原料(liao)混合得(de)很好(hao)。發動機應配備分離(li)錐、分離(li)支(zhi)架等分離(li)設備，風管(guan)可根據截面形狀和材料(liao)進行分類，在(zai)壓力和溫度的(de)(de)作用(yong)下，它們在(zai)模(mo)具區域組裝出(chu)模(mo)具的(de)(de)成型(xing)(xing)部分然(ran)后冷卻(que)成型(xing)(xing)以(yi)獲(huo)得(de)復合型(xing)(xing)材所需的(de)(de)加工方(fang)法，是現在(zai)比較常見的(de)(de)一種(zhong)方(fang)式。
