　　無縫鋼管是一種具有中空截面、周邊沒有接縫的長條鋼材。無縫鋼管 具有中空截面，大量用作輸送流體的管道，鋼管與圓鋼等實心鋼材相比，在抗彎抗扭強度相同時，重量較輕，是一種經濟截面鋼材，廣泛用于制造結構件和機械零件，如石油鉆桿、汽車傳動軸、自行車架以及建筑施工中用的鋼腳手架等。了解更多>>>>無縫鋼管產品

　　無縫鋼管用(yong)(yong)途(tu)很廣(guang)泛。一般(ban)用(yong)(yong)途(tu)的(de)無(wu)(wu)縫(feng)鋼(gang)管(guan)(guan)由普通碳素結(jie)構(gou)鋼(gang)、低合(he)金結(jie)構(gou)鋼(gang)或合(he)金結(jie)構(gou)鋼(gang)軋制，產量最多，主要(yao)用(yong)(yong)作輸送(song)流體的(de)管(guan)(guan)道(dao)或結(jie)構(gou)零件。.2、根據用(yong)(yong)途(tu)不(bu)同分三類供(gong)(gong)應(ying)(ying)：a、按(an)化學成分和機(ji)(ji)械(xie)性能(neng)供(gong)(gong)應(ying)(ying);b、按(an)機(ji)(ji)械(xie)性能(neng)供(gong)(gong)應(ying)(ying);c、按(an)水(shui)壓試(shi)(shi)驗供(gong)(gong)應(ying)(ying)。按(an)a、b類供(gong)(gong)應(ying)(ying)的(de)鋼(gang)管(guan)(guan)，如用(yong)(yong)于承(cheng)受液體壓力，也要(yao)進行(xing)水(shui)壓試(shi)(shi)驗。3、專門用(yong)(yong)途(tu)的(de)無(wu)(wu)縫(feng)管(guan)(guan)有鍋爐(lu)用(yong)(yong)無(wu)(wu)縫(feng)管(guan)(guan)、地質用(yong)(yong)無(wu)(wu)縫(feng)鋼(gang)管(guan)(guan)及(ji)石(shi)油(you)用(yong)(yong)無(wu)(wu)縫(feng)管(guan)(guan)等多種(zhong)。

　　焊接鋼管也稱焊(han)管(guan)(guan)(guan)(guan)(guan)，是用鋼板或鋼帶經過卷曲成型(xing)后焊(han)接(jie)(jie)制成的(de)鋼管(guan)(guan)(guan)(guan)(guan)鋼管(guan)(guan)(guan)(guan)(guan)。焊(han)接(jie)(jie)鋼管(guan)(guan)(guan)(guan)(guan)生產工藝簡單，生產效率高，品種(zhong)規(gui)格多，設備資少，但一般(ban)強(qiang)度低(di)于無(wu)縫鋼管(guan)(guan)(guan)(guan)(guan)。20世紀30年代以來(lai)，隨著優質(zhi)帶鋼連軋生產的(de)迅速發展以及(ji)焊(han)接(jie)(jie)和(he)檢驗技(ji)術的(de)進步，焊(han)縫質(zhi)量不斷(duan)提高，焊(han)接(jie)(jie)鋼管(guan)(guan)(guan)(guan)(guan)的(de)品種(zhong)規(gui)格日益(yi)增(zeng)多，并在越(yue)來(lai)越(yue)多的(de)領域代替(ti)了無(wu)縫鋼管(guan)(guan)(guan)(guan)(guan)。

　　焊接鋼管按焊(han)(han)(han)(han)(han)縫(feng)的(de)形式分(fen)為直(zhi)縫(feng)焊(han)(han)(han)(han)(han)管(guan)(guan)(guan)(guan)和螺(luo)旋(xuan)焊(han)(han)(han)(han)(han)管(guan)(guan)(guan)(guan)。 直(zhi)縫(feng)焊(han)(han)(han)(han)(han)管(guan)(guan)(guan)(guan)生產(chan)工藝簡單，生產(chan)效率高(gao)，成本低，發展較快。螺(luo)旋(xuan)焊(han)(han)(han)(han)(han)管(guan)(guan)(guan)(guan)的(de)強度(du)(du)(du)一般比(bi)直(zhi)縫(feng)焊(han)(han)(han)(han)(han)管(guan)(guan)(guan)(guan)高(gao)，能用較窄(zhai)的(de)坯料生產(chan)管(guan)(guan)(guan)(guan)徑(jing)(jing)較大(da)(da)的(de)焊(han)(han)(han)(han)(han)管(guan)(guan)(guan)(guan)，還(huan)可以用同(tong)樣寬度(du)(du)(du)的(de)坯料生產(chan)管(guan)(guan)(guan)(guan)徑(jing)(jing)不同(tong)的(de)焊(han)(han)(han)(han)(han)管(guan)(guan)(guan)(guan)。但是與相同(tong)長度(du)(du)(du)的(de)直(zhi)縫(feng)管(guan)(guan)(guan)(guan)相比(bi)，焊(han)(han)(han)(han)(han)縫(feng)長度(du)(du)(du)增加30~100%，而且生產(chan)速(su)度(du)(du)(du)較低。 因此，較小口徑(jing)(jing)的(de)焊(han)(han)(han)(han)(han)管(guan)(guan)(guan)(guan)大(da)(da)都采用直(zhi)縫(feng)焊(han)(han)(han)(han)(han)，大(da)(da)口徑(jing)(jing)焊(han)(han)(han)(han)(han)管(guan)(guan)(guan)(guan)則大(da)(da)多采用螺(luo)旋(xuan)焊(han)(han)(han)(han)(han)。
