class="khcont">西氣東輸鋼管技術(shù)標(biāo)準(zhǔn)要求錯(cuò)邊量小于2mm，由此，要求帶鋼的月牙彎必須小于8mm/5m，但標(biāo)準(zhǔn)和國內(nèi)標(biāo)準(zhǔn)GS/714164-93規(guī)定帶鋼的月牙彎為25mm/m，很難滿足這個(gè)要求。這就是加拿大為什么用鋼板而不用鋼卷來制作螺旋管的原因。何況螺旋焊管用機(jī)械擴(kuò)徑方法來應(yīng)力難度大，外防腐層厚度在螺旋焊縫處的厚度比管體上的要減薄近30％，這些都不能不列入工程考慮范圍之內(nèi)。制管全過程是一個(gè)系統(tǒng)工程，不僅僅限于學(xué)術(shù)研究上討論管體力學(xué)分析，不能避開管型制作工藝流程、應(yīng)力方法、無損檢測方式以及防腐效果諸多問題。力學(xué)分析只是其中一個(gè)重要方面，但不是全部，因此，螺旋焊管工藝及設(shè)備方面要適應(yīng)我國天然氣工業(yè)的發(fā)展，技術(shù)改造應(yīng)當(dāng)作為重點(diǎn)，例如預(yù)精焊、擴(kuò)徑等，同時(shí)，由于國內(nèi)競爭已大大飽和，不宜再建新的生產(chǎn)線。關(guān)于焊管“無縫化”工藝的解讀西方工業(yè)發(fā)達(dá)的產(chǎn)鋼大國焊管取代無縫管的個(gè)階段之所以是70年代，同焊管“無縫化”技術(shù)的成熟有關(guān)系。焊管能在質(zhì)量上優(yōu)于無縫管，主要是70年代冶金技術(shù)的發(fā)展使熱軋板卷可以作為焊管的質(zhì)優(yōu)、價(jià)廉、充足的原料，電子計(jì)算機(jī)技術(shù)的發(fā)展使焊管工藝可以全線連續(xù)自動，在線熱處理技術(shù)的發(fā)展使焊管在焊接后中頻退火處理、自動無損檢測技術(shù)的發(fā)展可以對焊縫和母材進(jìn)行質(zhì)量檢查，保證，從而使客戶放心使用而無后顧之優(yōu)。</div><p><img
