通風管道是一種空心方形(xing)的截面輕型(xing)薄(bo)壁鋼(gang)管,也稱為鋼(gang)制(zhi)冷彎型(xing)材。它是以Q235熱(re)軋或冷軋帶鋼(gang)或卷板為母材經(jing)冷彎曲加工成型(xing)后再經(jing)高頻焊(han)接制(zhi)成的方形(xing)截面形(xing)狀尺寸(cun)(cun)的型(xing)鋼(gang)。熱(re)軋特(te)厚(hou)壁方管除壁厚(hou)增厚(hou)外情況,其角部尺寸(cun)(cun)和邊部平直度(du)均達到甚至超(chao)過電阻焊(han)冷成型(xing)方管的水(shui)平。綜(zong)合力學性(xing)(xing)能(neng)好(hao)(hao),焊(han)接性(xing)(xing),冷,熱(re)加工性(xing)(xing)能(neng)和耐腐蝕性(xing)(xing)能(neng)均好(hao)(hao),具(ju)有良好(hao)(hao)的低(di)溫(wen)韌性(xing)(xing)。
通風管道的用途(tu)有建筑,機(ji)械制造,鋼(gang)鐵建設(she)等項目, 造船(chuan),太陽能發電(dian)(dian)(dian)支架(jia),鋼(gang)結構工(gong)程,電(dian)(dian)(dian)力工(gong)程,電(dian)(dian)(dian)廠,農業和化學機(ji)械,玻璃幕墻,汽車底(di)盤,機(ji)場(chang),鍋爐(lu)建造,高(gao)速路欄桿,房屋建筑,壓(ya)力容器,石(shi)油儲罐,橋梁,電(dian)(dian)(dian)站設(she)備,起重運輸機(ji)械及其他(ta)較高(gao)載荷的焊(han)接結構件(jian)等。
