向日葵視頻在線觀看: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,無縫鋼管分圓形(xing)(xing)和異形(xing)(xing)兩種,異形(xing)(xing)管(guan)(guan)(guan)(guan)有方形(xing)(xing)、橢(tuo)圓形(xing)(xing)、三角形(xing)(xing)、六角形(xing)(xing)、瓜子形(xing)(xing)、星(xing)形(xing)(xing)、 帶翅管(guan)(guan)(guan)(guan)多種復雜形(xing)(xing)狀。******直徑(jing)達650mm,最小直徑(jing)為 6mm。根據用(yong)途不同, 有厚壁管(guan)(guan)(guan)(guan)和薄壁管(guan)(guan)(guan)(guan)。無縫鋼管(guan)(guan)(guan)(guan)主要用(yong)做石油(you)地質鉆探管(guan)(guan)(guan)(guan)、石油(you)化工用(yong)的裂化管(guan)(guan)(guan)(guan)、鍋 爐管(guan)(guan)(guan)(guan)、軸(zhou)承管(guan)(guan)(guan)(guan)以及汽車(che)、拖拉機、航空用(yong)高(gao)精(jing)度結構(gou)鋼管(guan)(guan)(guan)(guan)。
20#無縫鋼管用(yong)途(tu)很廣(guang)泛。一般用(yong)途(tu)的無縫(feng)(feng)鋼(gang)管(guan)(guan)由普通的碳素結(jie)構鋼(gang)、低(di)合(he)金結(jie)構鋼(gang)或合(he)金結(jie)構鋼(gang)軋制,產量最(zui)多(duo),主要用(yong)作輸送流體的管(guan)(guan)道或結(jie)構零(ling)件(jian)。.2、根據用(yong)途(tu)不(bu)同(tong)分(fen)三類供(gong)應(ying):a、按(an)化學(xue)成分(fen)和機械性(xing)能(neng)(neng)供(gong)應(ying);b、按(an)機械性(xing)能(neng)(neng)供(gong)應(ying);c、按(an)水(shui)壓試驗(yan)供(gong)應(ying)。按(an)a、b類供(gong)應(ying)的鋼(gang)管(guan)(guan),如用(yong)于(yu)承受液體壓力(li),也要進行水(shui)壓試驗(yan)。3、專門用(yong)途(tu)的無縫(feng)(feng)管(guan)(guan)有鍋爐用(yong)無縫(feng)(feng)管(guan)(guan)、化工電力(li)用(yong),地質(zhi)用(yong)無縫(feng)(feng)鋼(gang)管(guan)(guan)及石油用(yong)無縫(feng)(feng)管(guan)(guan)等多(duo)種。
20#無縫鋼管具有中空(kong)截面,大(da)量用(yong)作輸送流體(ti)的管道(dao),如輸送石油、天然氣(qi)、煤氣(qi)、水及某些固體(ti)物料的管道(dao)等。鋼管與(yu)圓鋼等實(shi)心鋼材相比,在抗(kang)彎抗(kang)扭強度相同時,重量較輕,是一種經濟截面鋼材。
廣泛用(yong)(yong)于制(zhi)(zhi)造(zao)結構件和機械零件,如(ru)石(shi)油鉆桿、汽車傳動軸、自行車架以及(ji)建筑(zhu)施工(gong)中(zhong)用(yong)(yong)的(de)鋼(gang)腳手架等用(yong)(yong)鋼(gang)管(guan)制(zhi)(zhi)造(zao)環形零件,可提高材料(liao)利用(yong)(yong)率,簡化制(zhi)(zhi)造(zao)工(gong)序,節(jie)約材料(liao)和加(jia)工(gong)工(gong)時,已廣泛用(yong)(yong)鋼(gang)管(guan)來制(zhi)(zhi)造(zao)。
