熱鍍鋅方管也稱(chēng)焊管，是用鋼板或鋼帶經(jīng)過(guò)卷曲成型后焊接制成的鋼管。焊接鋼管生產(chǎn)工藝簡(jiǎn)單，生產(chǎn)效率高，品種規(guī)格多，設(shè)備投資少，但一般強(qiáng)度低于無(wú)縫鋼管。隨著好的熱鍍鋅方管軋生產(chǎn)的迅速發(fā)展以及焊接和檢驗(yàn)技術(shù)的進(jìn)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(lái)越多的領(lǐng)域代替了無(wú)縫鋼管。焊接鋼管按焊縫的形式分為直縫焊管和螺旋焊管，盤(pán)龍區(qū)***熱鍍鋅方管。直縫焊管生產(chǎn)工藝簡(jiǎn)單，生產(chǎn)效率高，盤(pán)龍區(qū)***熱鍍鋅方管，成本低，發(fā)展較快，盤(pán)龍區(qū)***熱鍍鋅方管。螺旋焊管的強(qiáng)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(zhǎng)度的直縫管相比，焊縫長(zhǎng)度增加百分之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。昆明熱鍍鋅方管報(bào)價(jià)表，云南贛僑鋼材廠家供應(yīng)。盤(pán)龍區(qū)***熱鍍鋅方管</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:
