不(bu)銹(xiu)鋼風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)主要(yao)(yao)用(yong)(yong)(yong)途：主要(yao)(yao)用(yong)(yong)(yong)在大(da)型鍋爐房通(tong)風(feng)(feng)(feng)排(pai)煙工程(cheng)、供暖(nuan)(nuan)、采暖(nuan)(nuan)設備排(pai)煙體(ti)系、廚房排(pai)煙工程(cheng)，大(da)型排(pai)煙、通(tong)風(feng)(feng)(feng)工程(cheng)，既體(ti)現了(le)外墻的(de)(de)美觀，又有(you)防風(feng)(feng)(feng)防雨防蟲的(de)(de)實(shi)用(yong)(yong)(yong)性(xing)，它堅久耐用(yong)(yong)(yong)，不(bu)老化，涇風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)，在現代(dai)修建(jian)方面(mian)增添了(le)現代(dai)化的(de)(de)氣(qi)息。風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)，是用(yong)(yong)(yong)于空氣(qi)輸(shu)送(song)和(he)分(fen)布的(de)(de)管(guan)(guan)(guan)(guan)道系統(tong)。有(you)復合風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)和(he)無機風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)兩種。復合風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)以Durkduct風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)為代(dai)表(biao)。可按截面(mian)形(xing)狀和(he)材(cai)質分(fen)類。鍍鋅風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)的(de)(de)優點(dian)：強度高，阻力(li)小，密封性(xing)能好，外形(xing)美觀，安裝(zhuang)簡單(dan)，使用(yong)(yong)(yong)壽命長。所用(yong)(yong)(yong)原材(cai)料均為本鋼鍍鋅鋼板。

不銹鋼風管的(de)特(te)點：外形美觀、內壁光滑、阻力小(xiao)、氣密性(xing)好、承(cheng)壓強(qiang)度高，能適(shi)合非(fei)常(chang)復雜的(de)排氣工程。風管內的(de)空(kong)(kong)氣流速對通風、空(kong)(kong)調(diao)系統(tong)的(de)經濟(ji)型(xing)有(you)較大(da)的(de)影(ying)響。流速高，風管斷面小(xiao)，鍍鋅板風管，材料耗用少，建(jian)造費用小(xiao)；但是系統(tong)的(de)阻力大(da)，動(dong)力消耗增大(da)，運用費用增加(jia)。同時接縫均勻平整、咬口緊密、連接力強(qiang)、密封性(xing)好。安全密封圈(quan)防漏系統(tong)。精(jing)巧的(de)螺旋壓制(zhi)楞筋工藝使不銹鋼風管具有(you)承(cheng)受壓力的(de)強(qiang)度，增加(jia)螺旋型(xing)楞筋后。

管(guan)(guan)(guan)道(dao)穿(chuan)墻或(huo)樓板處必(bi)須(xu)設置套管(guan)(guan)(guan)，圓形(xing)風(feng)管(guan)(guan)(guan)，其內(nei)(nei)徑應比管(guan)(guan)(guan)道(dao)（不(bu)(bu)保(bao)(bao)溫(wen)）或(huo)保(bao)(bao)溫(wen)層(ceng)(ceng)外徑大20-30mm。安裝(zhuang)在(zai)(zai)(zai)墻體內(nei)(nei)的(de)(de)套管(guan)(guan)(guan)，除塵(chen)風(feng)管(guan)(guan)(guan)，其兩端應與(yu)墻飾面相平(ping)；穿(chuan)樓板的(de)(de)套管(guan)(guan)(guan)應比建筑面層(ceng)(ceng)高(gao)30mm。管(guan)(guan)(guan)道(dao)的(de)(de)接頭焊縫不(bu)(bu)得設在(zai)(zai)(zai)套管(guan)(guan)(guan)內(nei)(nei)。在(zai)(zai)(zai)保(bao)(bao)溫(wen)工(gong)程竣(jun)工(gong)后，套管(guan)(guan)(guan)與(yu)保(bao)(bao)溫(wen)層(ceng)(ceng)外徑之(zhi)間的(de)(de)空隙(xi)用不(bu)(bu)燃保(bao)(bao)溫(wen)材料(liao)塞緊。通(tong)風(feng)管(guan)(guan)(guan)道(dao)吊裝(zhuang)：按系統編(bian)號和標記進行安裝(zhuang)；檢(jian)查安裝(zhuang)部位風(feng)管(guan)(guan)(guan)的(de)(de)尺寸，法蘭(lan)安裝(zhuang)是(shi)否正(zheng)確；風(feng)管(guan)(guan)(guan)及法蘭(lan)制作(zuo)允許偏差是(shi)否符合規定；風(feng)管(guan)(guan)(guan)安裝(zhuang)前應清(qing)除其內(nei)(nei)、外表(biao)面粉塵(chen)及管(guan)(guan)(guan)內(nei)(nei)雜物。
