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(he)異形(xing)(xing)兩種，異形(xing)(xing)管(guan)(guan)有(you)方(fang)形(xing)(xing)、橢(tuo)圓(yuan)形(xing)(xing)、三角(jiao)形(xing)(xing)、六(liu)角(jiao)形(xing)(xing)、瓜子形(xing)(xing)、星形(xing)(xing)、 帶翅管(guan)(guan)多種復雜形(xing)(xing)狀。材質：10#，20#，45#，16mn，27simn，12cr1movG，15crmoG，35crmo，42crmo等(deng)。根(gen)據用途不(bu)同， 有(you)厚壁(bi)管(guan)(guan)和(he)薄壁(bi)管(guan)(guan)。無(wu)縫鋼管(guan)(guan)主要用做石油地質鉆探(tan)管(guan)(guan)、石油化(hua)工用的裂化(hua)管(guan)(guan)、鍋 爐管(guan)(guan)、軸(zhou)承管(guan)(guan)以及汽車、拖拉機(ji)、航空(kong)用結構鋼管(guan)(guan)等(deng)等(deng)。
