通風管道是一種空心方形的截面(mian)(mian)輕型(xing)(xing)薄壁(bi)鋼(gang)管,也稱為鋼(gang)制冷(leng)(leng)彎(wan)型(xing)(xing)材(cai)。它是以Q235熱(re)軋(ya)或(huo)冷(leng)(leng)軋(ya)帶鋼(gang)或(huo)卷板為母材(cai)經(jing)冷(leng)(leng)彎(wan)曲加工成(cheng)型(xing)(xing)后再經(jing)高頻焊(han)接(jie)制成(cheng)的方形截面(mian)(mian)形狀尺寸(cun)的型(xing)(xing)鋼(gang)。熱(re)軋(ya)特厚壁(bi)方管除壁(bi)厚增厚外情況,其(qi)角部(bu)尺寸(cun)和邊(bian)部(bu)平(ping)直度均(jun)達到甚至(zhi)超過電阻焊(han)冷(leng)(leng)成(cheng)型(xing)(xing)方管的水平(ping)。綜(zong)合力學性(xing)(xing)(xing)能好,焊(han)接(jie)性(xing)(xing)(xing),冷(leng)(leng),熱(re)加工性(xing)(xing)(xing)能和耐(nai)腐蝕(shi)性(xing)(xing)(xing)能均(jun)好,具(ju)有良好的低溫韌性(xing)(xing)(xing)。
通風管道的用途有建(jian)筑(zhu),機(ji)械制造(zao),鋼(gang)鐵(tie)建(jian)設(she)等項目, 造(zao)船,太陽能(neng)發電支架,鋼(gang)結構(gou)工程,電力工程,電廠,農(nong)業(ye)和化學機(ji)械,玻璃(li)幕墻(qiang),汽車(che)底(di)盤,機(ji)場,鍋爐(lu)建(jian)造(zao),高速路(lu)欄(lan)桿(gan),房(fang)屋建(jian)筑(zhu),壓力容(rong)器,石油儲罐,橋梁,電站設(she)備,起重運(yun)輸機(ji)械及(ji)其(qi)他較高載荷(he)的焊接結構(gou)件等。
