焊接鋼管也稱焊管，是用鋼板或鋼帶經(jīng)過卷曲成型后焊接制成的鋼管。焊接鋼管生產(chǎn)工藝簡單，生產(chǎn)效率高，品種規(guī)格多，設(shè)備投資少，但一般強度低于無縫鋼管。20世紀30年代以來，隨著優(yōu)異帶鋼連軋生產(chǎn)的迅速發(fā)展以及焊接和檢驗技術(shù)的進步，焊縫質(zhì)量不斷提高，焊接鋼管的品種規(guī)格日益增多，并在越來越多的領(lǐng)域代替了無縫鋼管。焊接鋼管按焊縫的形式分為直縫焊管和螺旋焊管。 </p> <p> 直縫焊管生產(chǎn)工藝簡單，生產(chǎn)效率高，成本低，發(fā)展較快。螺旋焊管的強度一般比直縫焊管高，能用較窄的坯料生產(chǎn)管徑較大的焊管，還可以用同樣寬度的坯料生產(chǎn)管徑不同的焊管。但是與相同長度的直縫管相比，焊縫長度增加30~100 %，而且生產(chǎn)速度較低。因此，較小口徑的焊管大都采用直縫焊，大口徑焊管則大多采用螺旋焊。 </p>
