426無縫鋼管24小時裝貨

　　426無縫鋼管是由整塊金屬制成的，表面上沒有接縫的鋼管，稱為無縫鋼管。根據生產方法，無縫管分熱軋管、冷軋管、冷拔管、擠壓管、頂管等。按照斷面形狀，無縫鋼管分圓(yuan)形(xing)(xing)和異形(xing)(xing)兩種，異形(xing)(xing)管(guan)(guan)有(you)方形(xing)(xing)、橢(tuo)圓(yuan)形(xing)(xing)、三角形(xing)(xing)、六(liu)角形(xing)(xing)、瓜子(zi)形(xing)(xing)、星形(xing)(xing)、 帶翅管(guan)(guan)多種復(fu)雜形(xing)(xing)狀。材質(zhi)：10#，20#，45#，16mn，27simn，12cr1movG，15crmoG，35crmo，42crmo等。根(gen)據用(yong)途不同， 有(you)厚壁(bi)管(guan)(guan)和薄(bo)壁(bi)管(guan)(guan)。無縫鋼管(guan)(guan)主要用(yong)做石(shi)油(you)地質(zhi)鉆探管(guan)(guan)、石(shi)油(you)化工用(yong)的裂化管(guan)(guan)、鍋(guo) 爐管(guan)(guan)、軸承管(guan)(guan)以及汽車、拖拉機、航空用(yong)結構(gou)鋼管(guan)(guan)等等。
