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(fen)圓(yuan)形(xing)(xing)(xing)和異形(xing)(xing)(xing)兩種(zhong)，異形(xing)(xing)(xing)管(guan)(guan)(guan)有(you)方形(xing)(xing)(xing)、橢圓(yuan)形(xing)(xing)(xing)、三角形(xing)(xing)(xing)、六角形(xing)(xing)(xing)、瓜子(zi)形(xing)(xing)(xing)、星形(xing)(xing)(xing)、 帶翅管(guan)(guan)(guan)多種(zhong)復雜形(xing)(xing)(xing)狀。材質：10#，20#，45#，16mn，27simn，12cr1movG，15crmoG，35crmo，42crmo等(deng)(deng)。根據用(yong)途不同， 有(you)厚壁(bi)管(guan)(guan)(guan)和薄壁(bi)管(guan)(guan)(guan)。無(wu)縫鋼(gang)管(guan)(guan)(guan)主要用(yong)做石油地(di)質鉆探管(guan)(guan)(guan)、石油化(hua)工用(yong)的裂化(hua)管(guan)(guan)(guan)、鍋(guo) 爐管(guan)(guan)(guan)、軸承管(guan)(guan)(guan)以及汽車、拖拉機、航空用(yong)結構鋼(gang)管(guan)(guan)(guan)等(deng)(deng)等(deng)(deng)。
