管線用鋼管有不經(jīng)焊接的軋制無(wú)縫鋼管和焊接制造的UOE鋼管以及電焊鋼管。焊接鋼管可分為直徑大于20"的UOE鋼管和直徑24"以下的電焊鋼管。這些焊接鋼管是用鋼板焊接制成的，所以作為原料的鋼板，其強(qiáng)度和焊接部位質(zhì)量保證至關(guān)重要。 </p> <p> 電焊鋼管是將鋼板成形為圓弧狀后，采用電阻焊對(duì)圓弧縫隙連續(xù)焊接使之接合制成的鋼管。電焊鋼管外觀好、價(jià)格低，廣泛用于汽車部件和建筑材料。20世紀(jì)80年代后，出現(xiàn)了高頻焊接方法，并用于電焊鋼管。但這種電焊鋼管不能用于-50℃以下的極寒地區(qū)。原因是鋼管焊接時(shí)產(chǎn)生的氧化物在寒冷地區(qū)導(dǎo)致焊接部位低溫韌性顯著下降。 </p> <p> 為此，開(kāi)發(fā)出低溫下焊接部位韌性不下降的管線用電焊鋼管，其制造技術(shù)包括對(duì)焊接產(chǎn)生的氧化物形態(tài)、分布進(jìn)行控制的焊接技術(shù)以及對(duì)焊接部位全長(zhǎng)進(jìn)行快速實(shí)時(shí)檢測(cè)的超聲波探傷技術(shù)。 </p> <p> 在進(jìn)行控制氧化物的焊接技術(shù)開(kāi)發(fā)中，用模擬解析方法，查明了高頻焊接時(shí)焊接部位發(fā)生的現(xiàn)象。高頻焊接時(shí)，高頻電流流過(guò)鋼板對(duì)鋼板進(jìn)行加熱。由于電流集中在鋼板角部和端面，將這些部位加熱到鋼的熔點(diǎn)以上，而鋼板厚度中央溫度。因此，對(duì)鋼板兩側(cè)進(jìn)行加壓焊接時(shí)，鋼板內(nèi)部的氧化物堆積在焊縫的外側(cè)，焊后可以將這些氧化物掉。但是由于鋼板角部和端面發(fā)生急速冷卻，板厚內(nèi)的氧化物被封閉到焊縫的內(nèi)側(cè)。
