通風管道是一種(zhong)空心方(fang)形的截(jie)面輕(qing)型(xing)(xing)薄壁鋼(gang)管(guan),也稱為鋼(gang)制冷(leng)(leng)彎型(xing)(xing)材。它是以(yi)Q235熱軋或冷(leng)(leng)軋帶鋼(gang)或卷板為母材經冷(leng)(leng)彎曲加工(gong)成(cheng)(cheng)型(xing)(xing)后(hou)再經高頻焊接制成(cheng)(cheng)的方(fang)形截(jie)面形狀尺(chi)寸的型(xing)(xing)鋼(gang)。熱軋特厚壁方(fang)管(guan)除壁厚增厚外情況(kuang),其角部(bu)尺(chi)寸和邊(bian)部(bu)平直度均(jun)達到甚至超過電阻焊冷(leng)(leng)成(cheng)(cheng)型(xing)(xing)方(fang)管(guan)的水平。綜合力學性能(neng)(neng)好(hao),焊接性,冷(leng)(leng),熱加工(gong)性能(neng)(neng)和耐腐蝕性能(neng)(neng)均(jun)好(hao),具有良好(hao)的低溫(wen)韌(ren)性。
通風管道(dao)的用途(tu)有建(jian)筑,機(ji)械(xie)(xie)(xie)制造(zao),鋼鐵建(jian)設(she)等項目, 造(zao)船,太陽能發電(dian)支架,鋼結(jie)構(gou)工(gong)程,電(dian)力工(gong)程,電(dian)廠(chang),農業和化學(xue)機(ji)械(xie)(xie)(xie),玻璃(li)幕墻,汽車底盤,機(ji)場,鍋爐建(jian)造(zao),高速(su)路欄桿,房屋(wu)建(jian)筑,壓力容器(qi),石(shi)油儲罐,橋(qiao)梁(liang),電(dian)站設(she)備,起重運輸(shu)機(ji)械(xie)(xie)(xie)及其他(ta)較高載荷的焊接結(jie)構(gou)件等。
