黃瓜視頻下載: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(fen)圓形(xing)和(he)異形(xing)兩種(zhong),異形(xing)管(guan)(guan)有(you)方形(xing)、橢圓形(xing)、三角形(xing)、六角形(xing)、瓜(gua)子形(xing)、星(xing)形(xing)、 帶翅管(guan)(guan)多種(zhong)復雜形(xing)狀。******直徑(jing)達650mm,最(zui)小(xiao)直徑(jing)為 6mm。根據用(yong)(yong)途不(bu)同, 有(you)厚壁(bi)管(guan)(guan)和(he)薄壁(bi)管(guan)(guan)。無縫鋼管(guan)(guan)主要用(yong)(yong)做石(shi)油(you)地質鉆(zhan)探管(guan)(guan)、石(shi)油(you)化工用(yong)(yong)的裂(lie)化管(guan)(guan)、鍋 爐管(guan)(guan)、軸(zhou)承(cheng)管(guan)(guan)以及(ji)汽車、拖拉(la)機、航空用(yong)(yong)高精度結構(gou)鋼管(guan)(guan)。
20#無縫鋼管用(yong)(yong)途(tu)(tu)很(hen)廣泛。一般用(yong)(yong)途(tu)(tu)的(de)無(wu)縫(feng)(feng)鋼(gang)(gang)管(guan)由(you)普通的(de)碳素結(jie)構(gou)鋼(gang)(gang)、低合金(jin)結(jie)構(gou)鋼(gang)(gang)或合金(jin)結(jie)構(gou)鋼(gang)(gang)軋(ya)制(zhi),產量最多,主(zhu)要用(yong)(yong)作輸送流(liu)體的(de)管(guan)道或結(jie)構(gou)零件(jian)。.2、根據用(yong)(yong)途(tu)(tu)不(bu)同(tong)分(fen)三類供(gong)應(ying):a、按化學成分(fen)和(he)機(ji)械性(xing)能供(gong)應(ying);b、按機(ji)械性(xing)能供(gong)應(ying);c、按水(shui)壓試(shi)驗(yan)供(gong)應(ying)。按a、b類供(gong)應(ying)的(de)鋼(gang)(gang)管(guan),如(ru)用(yong)(yong)于承受液(ye)體壓力(li),也(ye)要進行(xing)水(shui)壓試(shi)驗(yan)。3、專門用(yong)(yong)途(tu)(tu)的(de)無(wu)縫(feng)(feng)管(guan)有鍋爐用(yong)(yong)無(wu)縫(feng)(feng)管(guan)、化工電(dian)力(li)用(yong)(yong),地質(zhi)用(yong)(yong)無(wu)縫(feng)(feng)鋼(gang)(gang)管(guan)及石(shi)油用(yong)(yong)無(wu)縫(feng)(feng)管(guan)等多種。
20#無縫鋼管具(ju)有中空截面,大量(liang)用作輸(shu)送(song)流體的管(guan)道,如輸(shu)送(song)石(shi)油(you)、天然氣(qi)、煤氣(qi)、水及某些固(gu)體物料(liao)的管(guan)道等。鋼(gang)管(guan)與圓鋼(gang)等實心鋼(gang)材相比(bi),在抗(kang)(kang)彎抗(kang)(kang)扭強度相同時,重(zhong)量(liang)較輕,是(shi)一種(zhong)經濟截面鋼(gang)材。
廣(guang)(guang)泛用于(yu)制(zhi)造(zao)結構件(jian)和(he)機械零件(jian),如石(shi)油鉆桿、汽車傳動軸、自行車架以(yi)及建筑施工中用的鋼腳手架等用鋼管(guan)(guan)制(zhi)造(zao)環形零件(jian),可(ke)提高(gao)材(cai)(cai)料(liao)(liao)利(li)用率,簡化制(zhi)造(zao)工序,節約材(cai)(cai)料(liao)(liao)和(he)加工工時,已(yi)廣(guang)(guang)泛用鋼管(guan)(guan)來制(zhi)造(zao)。
