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(liang)種，異形(xing)(xing)管(guan)有方形(xing)(xing)、橢(tuo)圓(yuan)形(xing)(xing)、三角形(xing)(xing)、六(liu)角形(xing)(xing)、瓜子形(xing)(xing)、星形(xing)(xing)、 帶(dai)翅管(guan)多種復雜形(xing)(xing)狀。材質(zhi)：10#，20#，45#，16mn，27simn，12cr1movG，15crmoG，35crmo，42crmo等。根據(ju)用途不同， 有厚壁(bi)管(guan)和(he)薄壁(bi)管(guan)。無縫鋼(gang)管(guan)主要用做(zuo)石油地質(zhi)鉆(zhan)探(tan)管(guan)、石油化工用的裂(lie)化管(guan)、鍋 爐管(guan)、軸承管(guan)以及汽(qi)車、拖拉機、航空用結(jie)構鋼(gang)管(guan)等等。
