class="khcont">直縫電阻焊鋼管與流體輸送用無縫鋼管相比具有相當(dāng)?shù)募夹g(shù)優(yōu)勢(shì)，例如焊管壁厚較薄，尺寸精度較高，等等。檢查合格的鋼管耐力已達(dá)到2800psi(13MPa)，而管線管水壓試驗(yàn)小合格壓力為1870psi(19MPa)，所試驗(yàn)鋼管耐壓小合格壓力為930psi(4MPa)，這種用普通Q235材質(zhì)制成的焊管已達(dá)到美國(guó)石油學(xué)會(huì)API51關(guān)于高材質(zhì)X52級(jí)鋼種的小限壓力規(guī)定。關(guān)于直縫電阻焊鋼管與流體輸送用無縫鋼管的經(jīng)濟(jì)性對(duì)比，由于生產(chǎn)成本低，直縫電阻焊鋼管的銷售價(jià)格比流體輸送用無縫鋼管低，實(shí)際采購(gòu)情況表明，直縫電阻焊鋼管比流體輸送無縫鋼管每噸要低于1000元左右，并且隨著口徑的增大，差價(jià)可高達(dá)2000多元。這也是目前上大量發(fā)展大、中口徑直縫電阻焊管線輸送管、石油套管、油管的重要原因。無縫化鋼管無縫化鋼管結(jié)束語(yǔ)在《資本論》的序言中說:“工業(yè)較發(fā)達(dá)的向不發(fā)達(dá)所顯示的，只是后來者未來的景象”。西方工業(yè)發(fā)達(dá)鋼管生產(chǎn)結(jié)構(gòu)成功轉(zhuǎn)型及其形成的由無縫管數(shù)量逐漸減少、焊管數(shù)量逐漸上升的替代路徑，這一景象在中國(guó)90年代已經(jīng)初顯端倪，也開始印證了的預(yù)言。因此，我國(guó)焊管發(fā)展方向應(yīng)當(dāng)是:管型上重點(diǎn)發(fā)展直縫焊管，這個(gè)基本點(diǎn)不能動(dòng)搖;在技術(shù)上強(qiáng)力推行無縫化技術(shù);重點(diǎn)焊管企業(yè)向中、高層技術(shù)領(lǐng)域發(fā)展;螺旋焊管應(yīng)當(dāng)著力于進(jìn)行技術(shù)改造，提高產(chǎn)品的檔次和質(zhì)量，擴(kuò)大自身的市場(chǎng)份額。
