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)和(he)異形(xing)兩種，異形(xing)管有方形(xing)、橢圓(yuan)形(xing)、三角(jiao)形(xing)、六角(jiao)形(xing)、瓜子(zi)形(xing)、星形(xing)、 帶翅管多種復雜形(xing)狀(zhuang)。材質(zhi)：10#，20#，45#，16mn，27simn，12cr1movG，15crmoG，35crmo，42crmo等。根據用(yong)途不同(tong)， 有厚壁管和(he)薄(bo)壁管。無(wu)縫鋼管主要用(yong)做石油地質(zhi)鉆(zhan)探管、石油化工用(yong)的裂化管、鍋 爐(lu)管、軸承管以及汽車、拖拉機、航空用(yong)結構鋼管等等。
