焊接鋼管也稱焊管，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。20世紀(jì)30年代以來(lái)，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(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。 </p> <p> 直縫焊管生產(chǎn)工藝簡(jiǎn)單，生產(chǎn)效率高，成本低，發(fā)展較快。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> <p> <br /> </p> <p> <br /> 衡水方管多少錢(qián)熱鍍管的性能有哪些？</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:

（1）將要對(duì)接的兩根鋼管放在同一平面的同一軸線上。 </p> <p> （2）保持兩管端部間隙在2-3mm之間。為保證焊接間隙距離，可在兩管間隙之間加墊。 </p> <p> （3）保證對(duì)接鋼管的坡口角度。 </p> <p> （4）鋼管焊接后30分鐘內(nèi)不得受外力移動(dòng)，否則對(duì)接焊縫會(huì)開(kāi)裂，影響鋼管的使用效果。 </p> <p> （5）對(duì)接焊縫如需進(jìn)行無(wú)損檢測(cè)（X射線底片或超聲波探傷），在條件允許的情況下，應(yīng)在焊接完成后24小時(shí)內(nèi)進(jìn)行。 </p> <p> 2、法蘭連接 </p> <p> （1）金屬法蘭套在連接件上，并對(duì)兩個(gè)相應(yīng)的連接件進(jìn)行校正，使兩個(gè)連接法蘭垂直于管道中心線，表面平行。 </p>
