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)和(he)異(yi)形(xing)(xing)兩種(zhong)，異(yi)形(xing)(xing)管有(you)方形(xing)(xing)、橢圓形(xing)(xing)、三角形(xing)(xing)、六角形(xing)(xing)、瓜子形(xing)(xing)、星形(xing)(xing)、 帶翅管多種(zhong)復雜形(xing)(xing)狀。材(cai)質(zhi)：10#，20#，45#，16mn，27simn，12cr1movG，15crmoG，35crmo，42crmo等。根據用途不同(tong)， 有(you)厚(hou)壁管和(he)薄(bo)壁管。無縫鋼(gang)管主要用做石(shi)油地(di)質(zhi)鉆探管、石(shi)油化(hua)工用的裂化(hua)管、鍋(guo) 爐管、軸(zhou)承管以及汽車、拖拉機、航空用結構鋼(gang)管等等。
