風(feng)(feng)(feng)(feng)(feng)管(guan)，是用于空氣輸(shu)送和(he)分(fen)(fen)(fen)布(bu)的管(guan)道系統。有復合風(feng)(feng)(feng)(feng)(feng)管(guan)和(he)無機風(feng)(feng)(feng)(feng)(feng)管(guan)兩種。風(feng)(feng)(feng)(feng)(feng)管(guan)可(ke)(ke)按(an)截(jie)面(mian)(mian)形(xing)狀和(he)材質(zhi)分(fen)(fen)(fen)類。風(feng)(feng)(feng)(feng)(feng)管(guan)制(zhi)作(zuo)(zuo)不銹(xiu)鋼風(feng)(feng)(feng)(feng)(feng)管(guan)制(zhi)作(zuo)(zuo)是在咬口縫、鉚釘縫、法蘭翻邊四角(jiao)等縫隙(xi)處涂上(shang)密(mi)(mi)封(feng)膠(jiao)（如中性玻璃膠(jiao)）。涂密(mi)(mi)封(feng)膠(jiao)前應清除(chu)表面(mian)(mian)塵土(tu)和(he)油污(wu)。按(an)截(jie)面(mian)(mian)形(xing)狀，風(feng)(feng)(feng)(feng)(feng)管(guan)可(ke)(ke)分(fen)(fen)(fen)為圓(yuan)形(xing)風(feng)(feng)(feng)(feng)(feng)管(guan)，矩形(xing)風(feng)(feng)(feng)(feng)(feng)管(guan)，扁圓(yuan)風(feng)(feng)(feng)(feng)(feng)管(guan)等多種，其中圓(yuan)形(xing)風(feng)(feng)(feng)(feng)(feng)管(guan)阻力小但高度尺寸(cun)大，制(zhi)作(zuo)(zuo)復雜(za)。所以應用以矩形(xing)風(feng)(feng)(feng)(feng)(feng)管(guan)為主。按(an)材質(zhi)，風(feng)(feng)(feng)(feng)(feng)管(guan)可(ke)(ke)分(fen)(fen)(fen)為金屬風(feng)(feng)(feng)(feng)(feng)管(guan)，復合風(feng)(feng)(feng)(feng)(feng)管(guan)，高分(fen)(fen)(fen)子(zi)風(feng)(feng)(feng)(feng)(feng)管(guan)。
