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，無縫鋼管分圓形(xing)(xing)(xing)(xing)(xing)和異形(xing)(xing)(xing)(xing)(xing)兩種，異形(xing)(xing)(xing)(xing)(xing)管(guan)有(you)方形(xing)(xing)(xing)(xing)(xing)、橢(tuo)圓形(xing)(xing)(xing)(xing)(xing)、三(san)角(jiao)形(xing)(xing)(xing)(xing)(xing)、六角(jiao)形(xing)(xing)(xing)(xing)(xing)、瓜(gua)子(zi)形(xing)(xing)(xing)(xing)(xing)、星形(xing)(xing)(xing)(xing)(xing)、 帶翅管(guan)多種復雜形(xing)(xing)(xing)(xing)(xing)狀。材(cai)質(zhi)(zhi)：10#，20#，45#，16mn，27simn，12cr1movG，15crmoG，35crmo，42crmo等。根據用途不同(tong)， 有(you)厚(hou)壁管(guan)和薄(bo)壁管(guan)。無(wu)縫鋼管(guan)主要(yao)用做石油地(di)質(zhi)(zhi)鉆探管(guan)、石油化(hua)工(gong)用的裂化(hua)管(guan)、鍋 爐(lu)管(guan)、軸承(cheng)管(guan)以及汽車、拖拉機、航(hang)空用結構鋼管(guan)等等。
