直縫管介紹

直zhi縫feng管guan是shi指zhi焊han縫feng與yu鋼gang管guan縱zong向xiang平ping行xing的de鋼gang管guan。一yi般ban也ye稱cheng為wei直zhi縫feng焊han管guan或huo直zhi縫feng鋼gang管guan。直zhi縫feng管guan是shi通tong過guo高gao頻pin焊han接jie機ji組zu將jiang一yi定ding規gui格ge的de長chang條tiao形xing鋼gang帶dai卷juan製zhi並bing采cai用yong直zhi縫feng焊han接jie而er成cheng。直zhi縫feng管guan規gui格ge用yong公gong稱cheng口kou徑jing表biao示shi，按an壁bi厚hou可ke分fen為wei薄bo壁bi直zhi縫feng管guan和he厚hou壁bi直zhi縫feng管guan兩liang種zhong。按an形xing狀zhuang可ke分fen為wei圓yuan形xing、方形或異形管等。

直縫鋼管生產技術的發展始於建設製造業。正由於直縫鋼管與人類生活、生(sheng)產(chan)活(huo)動(dong)密(mi)不(bu)可(ke)分(fen)，直(zhi)縫(feng)鋼(gang)管(guan)工(gong)業(ye)的(de)生(sheng)產(chan)技(ji)術(shu)不(bu)僅(jin)發(fa)展(zhan)迅(xun)速(su)，而(er)且(qie)推(tui)陳(chen)出(chu)新(xin)，直(zhi)縫(feng)鋼(gang)管(guan)生(sheng)產(chan)在(zai)鋼(gang)鐵(tie)工(gong)業(ye)中(zhong)占(zhan)有(you)不(bu)可(ke)替(ti)代(dai)的(de)位(wei)置(zhi)。直(zhi)縫(feng)鋼(gang)管(guan)不(bu)僅(jin)用(yong)於(yu)輸(shu)送(song)流(liu)體(ti)和(he)粉(fen)狀(zhuang)固(gu)體(ti)、交換熱能、製造機械零件和容器，它還是一種經濟鋼材。用直縫鋼管製造建築結構網架
、支柱和機械支架
，可以減輕重量，節省金屬20～40%，而且可實現工廠化機械化施工。
