通風管道是一種空心方形的截面輕型(xing)薄壁(bi)(bi)鋼管,也稱為鋼制冷彎型(xing)材。它是以Q235熱軋或(huo)冷軋帶鋼或(huo)卷板為母(mu)材經冷彎曲加(jia)工(gong)(gong)成(cheng)型(xing)后再經高頻焊(han)接制成(cheng)的方形截面形狀尺寸(cun)的型(xing)鋼。熱軋特厚壁(bi)(bi)方管除(chu)壁(bi)(bi)厚增厚外情(qing)況,其角(jiao)部尺寸(cun)和邊部平直(zhi)度均(jun)達(da)到甚至(zhi)超過電阻焊(han)冷成(cheng)型(xing)方管的水平。綜合力學性(xing)(xing)(xing)能(neng)(neng)好,焊(han)接性(xing)(xing)(xing),冷,熱加(jia)工(gong)(gong)性(xing)(xing)(xing)能(neng)(neng)和耐腐蝕性(xing)(xing)(xing)能(neng)(neng)均(jun)好,具有良好的低溫韌性(xing)(xing)(xing)。
通風管道的(de)用途(tu)有建(jian)筑,機(ji)械(xie)制造(zao),鋼鐵(tie)建(jian)設等(deng)項目, 造(zao)船(chuan),太陽能(neng)發電(dian)(dian)支(zhi)架,鋼結構(gou)工(gong)程(cheng),電(dian)(dian)力(li)工(gong)程(cheng),電(dian)(dian)廠,農業和(he)化(hua)學(xue)機(ji)械(xie),玻璃幕墻,汽(qi)車底盤,機(ji)場,鍋爐建(jian)造(zao),高速路欄桿,房屋建(jian)筑,壓力(li)容器(qi),石油儲罐,橋梁,電(dian)(dian)站設備,起(qi)重運輸機(ji)械(xie)及其他較高載荷(he)的(de)焊(han)接結構(gou)件等(deng)。
