小加工廠無處不在,但很難白鐵加工廠家形成一個大型加工廠,形成規模效應。產品大多是低端產品,在國際市場上沒有競爭力,缺正規白鐵加工乏品牌和(he)聲(sheng)譽,整個加工(gong)工(gong)藝和(he)缺乏創(chuang)新。一般來說,成都白鐵加工(gong)行業發(fa)展(zhan)非常快,但(dan)是密集程度(du)太低,缺乏科技創(chuang)新、市場供求失衡突出這(zhe)些問題。

不銹鋼正規白鐵加工風管的空氣流動性好，有效通流面積大，由于強度大，因此風管振動引起的低頻噪聲更小，空白鐵加工廠家氣流(liu)動性(xing)能好，系(xi)統壓降(jiang)小，日(ri)常運行系(xi)統耗電量少。目前還可以采用扁橢圓形風管(guan)來(lai)降(jiang)低風管(guan)的占用空間高度，由于風管(guan)的兩邊是圓形，所以氣流(liu)穩(wen)定，風管(guan)的剛性(xing)好，外(wai)露安裝美(mei)觀性(xing)好，是比較理(li)想的風管(guan)系(xi)列。
