茄子視頻黃色: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)(xing)(xing)(xing)和異形(xing)(xing)(xing)(xing)(xing)兩種，異形(xing)(xing)(xing)(xing)(xing)管(guan)(guan)有方形(xing)(xing)(xing)(xing)(xing)、橢圓形(xing)(xing)(xing)(xing)(xing)、三角形(xing)(xing)(xing)(xing)(xing)、六角形(xing)(xing)(xing)(xing)(xing)、瓜子形(xing)(xing)(xing)(xing)(xing)、星形(xing)(xing)(xing)(xing)(xing)、 帶(dai)翅管(guan)(guan)多種復雜形(xing)(xing)(xing)(xing)(xing)狀。******直徑達650mm，最小直徑為 6mm。根據(ju)用(yong)途不同， 有厚壁管(guan)(guan)和薄(bo)壁管(guan)(guan)。無縫(feng)鋼(gang)管(guan)(guan)主要用(yong)做石(shi)油地質(zhi)鉆探管(guan)(guan)、石(shi)油化工用(yong)的裂化管(guan)(guan)、鍋 爐(lu)管(guan)(guan)、軸(zhou)承管(guan)(guan)以及汽車、拖拉機、航(hang)空(kong)用(yong)高精度(du)結構鋼(gang)管(guan)(guan)。

　　20#無縫鋼管用(yong)(yong)(yong)途(tu)(tu)很廣泛。一般(ban)用(yong)(yong)(yong)途(tu)(tu)的無(wu)(wu)縫(feng)(feng)鋼(gang)(gang)(gang)(gang)管(guan)(guan)(guan)(guan)由普通的碳素結(jie)構鋼(gang)(gang)(gang)(gang)、低(di)合金結(jie)構鋼(gang)(gang)(gang)(gang)或(huo)合金結(jie)構鋼(gang)(gang)(gang)(gang)軋(ya)制(zhi)，產量最多(duo)，主要(yao)用(yong)(yong)(yong)作輸送流體(ti)的管(guan)(guan)(guan)(guan)道或(huo)結(jie)構零(ling)件。.2、根據用(yong)(yong)(yong)途(tu)(tu)不同分三類供(gong)(gong)(gong)應(ying)：a、按(an)化學成分和機械性能供(gong)(gong)(gong)應(ying);b、按(an)機械性能供(gong)(gong)(gong)應(ying);c、按(an)水壓試驗(yan)供(gong)(gong)(gong)應(ying)。按(an)a、b類供(gong)(gong)(gong)應(ying)的鋼(gang)(gang)(gang)(gang)管(guan)(guan)(guan)(guan)，如(ru)用(yong)(yong)(yong)于承受液(ye)體(ti)壓力，也(ye)要(yao)進(jin)行(xing)水壓試驗(yan)。3、專門用(yong)(yong)(yong)途(tu)(tu)的無(wu)(wu)縫(feng)(feng)管(guan)(guan)(guan)(guan)有鍋爐用(yong)(yong)(yong)無(wu)(wu)縫(feng)(feng)管(guan)(guan)(guan)(guan)、化工電力用(yong)(yong)(yong)，地質用(yong)(yong)(yong)無(wu)(wu)縫(feng)(feng)鋼(gang)(gang)(gang)(gang)管(guan)(guan)(guan)(guan)及石油(you)用(yong)(yong)(yong)無(wu)(wu)縫(feng)(feng)管(guan)(guan)(guan)(guan)等多(duo)種。

　　20#無縫鋼管具有中空截面(mian)，大量(liang)(liang)用作輸送流體(ti)的管(guan)道，如(ru)輸送石(shi)油、天然氣、煤氣、水(shui)及(ji)某些(xie)固體(ti)物料(liao)的管(guan)道等。鋼(gang)管(guan)與圓鋼(gang)等實心鋼(gang)材(cai)相比，在抗(kang)彎抗(kang)扭強度(du)相同時，重量(liang)(liang)較輕，是一種經(jing)濟截面(mian)鋼(gang)材(cai)。

　　廣(guang)泛用(yong)于(yu)制造結(jie)構件和機(ji)械(xie)零件，如(ru)石油鉆(zhan)桿、汽車(che)傳動軸(zhou)、自(zi)行車(che)架以及建筑施工中用(yong)的(de)鋼腳手架等用(yong)鋼管制造環形零件，可提高(gao)材料利用(yong)率，簡化制造工序(xu)，節約材料和加工工時(shi)，已(yi)廣(guang)泛用(yong)鋼管來制造。
