鯨魚視頻: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)(xing)和異形(xing)(xing)(xing)(xing)兩種，異形(xing)(xing)(xing)(xing)管(guan)(guan)(guan)有方形(xing)(xing)(xing)(xing)、橢圓(yuan)形(xing)(xing)(xing)(xing)、三角(jiao)形(xing)(xing)(xing)(xing)、六角(jiao)形(xing)(xing)(xing)(xing)、瓜(gua)子形(xing)(xing)(xing)(xing)、星形(xing)(xing)(xing)(xing)、 帶翅管(guan)(guan)(guan)多種復雜形(xing)(xing)(xing)(xing)狀。******直(zhi)徑達(da)650mm，最小直(zhi)徑為 6mm。根據用途(tu)不同， 有厚壁管(guan)(guan)(guan)和薄(bo)壁管(guan)(guan)(guan)。無縫鋼管(guan)(guan)(guan)主要用做石油地(di)質鉆探管(guan)(guan)(guan)、石油化(hua)工用的裂化(hua)管(guan)(guan)(guan)、鍋 爐管(guan)(guan)(guan)、軸承管(guan)(guan)(guan)以及汽車、拖拉(la)機、航空用高精度結構鋼管(guan)(guan)(guan)。

　　20#無縫鋼管用(yong)(yong)(yong)途很廣(guang)泛。一般(ban)用(yong)(yong)(yong)途的(de)無(wu)縫(feng)鋼(gang)(gang)(gang)管(guan)由(you)普通的(de)碳素結(jie)構鋼(gang)(gang)(gang)、低合(he)金(jin)結(jie)構鋼(gang)(gang)(gang)或合(he)金(jin)結(jie)構鋼(gang)(gang)(gang)軋制，產(chan)量(liang)最多，主要(yao)用(yong)(yong)(yong)作輸(shu)送流體的(de)管(guan)道(dao)或結(jie)構零件(jian)。.2、根據用(yong)(yong)(yong)途不同分三類供(gong)(gong)(gong)應(ying)(ying)：a、按(an)化學(xue)成分和機(ji)械性能(neng)供(gong)(gong)(gong)應(ying)(ying);b、按(an)機(ji)械性能(neng)供(gong)(gong)(gong)應(ying)(ying);c、按(an)水壓試驗(yan)供(gong)(gong)(gong)應(ying)(ying)。按(an)a、b類供(gong)(gong)(gong)應(ying)(ying)的(de)鋼(gang)(gang)(gang)管(guan)，如用(yong)(yong)(yong)于承(cheng)受(shou)液體壓力，也要(yao)進行水壓試驗(yan)。3、專門用(yong)(yong)(yong)途的(de)無(wu)縫(feng)管(guan)有鍋爐(lu)用(yong)(yong)(yong)無(wu)縫(feng)管(guan)、化工電力用(yong)(yong)(yong)，地質用(yong)(yong)(yong)無(wu)縫(feng)鋼(gang)(gang)(gang)管(guan)及石油用(yong)(yong)(yong)無(wu)縫(feng)管(guan)等多種。

　　20#無縫鋼管具有中空(kong)截(jie)面，大(da)量用(yong)作輸(shu)送流體的管道，如輸(shu)送石(shi)油(you)、天(tian)然氣、煤氣、水及某(mou)些固(gu)體物料(liao)的管道等。鋼(gang)管與(yu)圓鋼(gang)等實心鋼(gang)材相比，在抗彎抗扭強度相同時，重量較輕(qing)，是一(yi)種經(jing)濟截(jie)面鋼(gang)材。

　　廣泛(fan)用(yong)于制(zhi)造結構件和機械零件，如石油鉆桿、汽車傳動軸、自行車架以(yi)及(ji)建筑施工(gong)中用(yong)的鋼(gang)(gang)腳手架等(deng)用(yong)鋼(gang)(gang)管制(zhi)造環(huan)形零件，可提高材(cai)料(liao)利用(yong)率，簡化制(zhi)造工(gong)序，節約(yue)材(cai)料(liao)和加工(gong)工(gong)時(shi)，已廣泛(fan)用(yong)鋼(gang)(gang)管來(lai)制(zhi)造。
