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)和異形(xing)兩(liang)種(zhong)，異形(xing)管(guan)有方形(xing)、橢(tuo)圓(yuan)形(xing)、三角形(xing)、六角形(xing)、瓜子(zi)形(xing)、星形(xing)、 帶翅管(guan)多種(zhong)復雜形(xing)狀。材(cai)質：10#，20#，45#，16mn，27simn，12cr1movG，15crmoG，35crmo，42crmo等。根據用途不同， 有厚壁(bi)管(guan)和薄壁(bi)管(guan)。無縫鋼(gang)管(guan)主要用做石油地(di)質鉆探管(guan)、石油化(hua)工(gong)用的裂化(hua)管(guan)、鍋 爐管(guan)、軸承管(guan)以及汽車、拖拉機、航空用結構鋼(gang)管(guan)等等。
