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(fen)圓形(xing)(xing)(xing)和(he)異形(xing)(xing)(xing)兩(liang)種(zhong)，異形(xing)(xing)(xing)管(guan)有(you)(you)方形(xing)(xing)(xing)、橢(tuo)圓形(xing)(xing)(xing)、三(san)角(jiao)形(xing)(xing)(xing)、六(liu)角(jiao)形(xing)(xing)(xing)、瓜子形(xing)(xing)(xing)、星形(xing)(xing)(xing)、 帶翅管(guan)多(duo)種(zhong)復雜形(xing)(xing)(xing)狀(zhuang)。材質：10#，20#，45#，16mn，27simn，12cr1movG，15crmoG，35crmo，42crmo等。根據用(yong)途不同， 有(you)(you)厚(hou)壁管(guan)和(he)薄壁管(guan)。無縫鋼(gang)管(guan)主要(yao)用(yong)做石(shi)油地(di)質鉆(zhan)探管(guan)、石(shi)油化(hua)工用(yong)的(de)裂化(hua)管(guan)、鍋 爐管(guan)、軸承管(guan)以及汽車、拖拉機(ji)、航(hang)空用(yong)結構鋼(gang)管(guan)等等。
