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，無縫鋼管分圓形(xing)(xing)(xing)(xing)(xing)和異(yi)形(xing)(xing)(xing)(xing)(xing)兩種(zhong)(zhong)，異(yi)形(xing)(xing)(xing)(xing)(xing)管(guan)有方形(xing)(xing)(xing)(xing)(xing)、橢圓形(xing)(xing)(xing)(xing)(xing)、三角(jiao)形(xing)(xing)(xing)(xing)(xing)、六角(jiao)形(xing)(xing)(xing)(xing)(xing)、瓜子形(xing)(xing)(xing)(xing)(xing)、星形(xing)(xing)(xing)(xing)(xing)、 帶翅管(guan)多種(zhong)(zhong)復雜形(xing)(xing)(xing)(xing)(xing)狀。材質(zhi)：10#，20#，45#，16mn，27simn，12cr1movG，15crmoG，35crmo，42crmo等。根據用(yong)途不同， 有厚壁管(guan)和薄(bo)壁管(guan)。無縫鋼(gang)管(guan)主要(yao)用(yong)做石(shi)油地質(zhi)鉆探管(guan)、石(shi)油化(hua)工用(yong)的裂化(hua)管(guan)、鍋 爐管(guan)、軸承管(guan)以及(ji)汽車、拖拉機、航空用(yong)結構(gou)鋼(gang)管(guan)等等。
