草草視頻:20#無縫鋼管廠家現貨生產:無縫鋼管由圓鋼經過高溫穿孔制成,表面上無焊縫的鋼管,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、擠壓管等。按照斷面形狀,無縫鋼管分圓(yuan)形(xing)(xing)(xing)和異形(xing)(xing)(xing)兩種,異形(xing)(xing)(xing)管(guan)(guan)(guan)有方形(xing)(xing)(xing)、橢圓(yuan)形(xing)(xing)(xing)、三角形(xing)(xing)(xing)、六角形(xing)(xing)(xing)、瓜子形(xing)(xing)(xing)、星形(xing)(xing)(xing)、 帶翅管(guan)(guan)(guan)多種復雜形(xing)(xing)(xing)狀。******直徑達(da)650mm,最小直徑為 6mm。根據用途(tu)不同, 有厚壁管(guan)(guan)(guan)和薄壁管(guan)(guan)(guan)。無(wu)縫鋼管(guan)(guan)(guan)主(zhu)要用做石油地(di)質鉆探管(guan)(guan)(guan)、石油化(hua)工(gong)用的(de)裂化(hua)管(guan)(guan)(guan)、鍋 爐管(guan)(guan)(guan)、軸承管(guan)(guan)(guan)以(yi)及汽(qi)車、拖拉機、航空用高(gao)精度結構(gou)鋼管(guan)(guan)(guan)。
20#無縫鋼管用(yong)途很廣泛。一般(ban)用(yong)途的無縫鋼(gang)管(guan)(guan)由普(pu)通(tong)的碳素結(jie)構(gou)鋼(gang)、低合金結(jie)構(gou)鋼(gang)或合金結(jie)構(gou)鋼(gang)軋制,產量最多(duo),主要(yao)用(yong)作輸送流體的管(guan)(guan)道或結(jie)構(gou)零件。.2、根據用(yong)途不同分(fen)(fen)三類(lei)供(gong)應(ying)(ying):a、按(an)化學成分(fen)(fen)和機械性能供(gong)應(ying)(ying);b、按(an)機械性能供(gong)應(ying)(ying);c、按(an)水壓試(shi)驗(yan)(yan)供(gong)應(ying)(ying)。按(an)a、b類(lei)供(gong)應(ying)(ying)的鋼(gang)管(guan)(guan),如用(yong)于承受液體壓力,也(ye)要(yao)進行水壓試(shi)驗(yan)(yan)。3、專門(men)用(yong)途的無縫管(guan)(guan)有鍋爐用(yong)無縫管(guan)(guan)、化工電力用(yong),地質用(yong)無縫鋼(gang)管(guan)(guan)及石油(you)用(yong)無縫管(guan)(guan)等多(duo)種。
20#無縫鋼管具有中空截面,大量用作輸(shu)送(song)流體的(de)(de)管道(dao),如輸(shu)送(song)石油(you)、天(tian)然(ran)氣(qi)(qi)、煤(mei)氣(qi)(qi)、水及某些(xie)固體物料(liao)的(de)(de)管道(dao)等(deng)(deng)。鋼管與圓鋼等(deng)(deng)實心鋼材相比,在抗彎抗扭強度相同時,重量較輕,是一(yi)種經濟截面鋼材。
廣泛(fan)(fan)用(yong)于制(zhi)造結構件(jian)和機(ji)械零件(jian),如石油鉆桿、汽車(che)傳動軸、自行車(che)架以及建筑施(shi)工中用(yong)的鋼(gang)腳手架等(deng)用(yong)鋼(gang)管制(zhi)造環(huan)形零件(jian),可提高材料利(li)用(yong)率,簡化制(zhi)造工序,節約材料和加工工時,已廣泛(fan)(fan)用(yong)鋼(gang)管來制(zhi)造。
