class="khcont">無縫化鋼管依據(jù)成型方式不同分為無縫鋼管、焊接鋼管和熱擴(kuò)管等幾類。無縫鋼管執(zhí)行標(biāo)準(zhǔn)為《低中壓輸送流體用無縫鋼管》(GB/T8163-1999)，是指利用柱狀鋼坯加熱，模具穿孔方式生產(chǎn)的熱軋鋼管和利用冷拔機(jī)組將原管拉伸方式生產(chǎn)的冷拔鋼管。該類鋼管特點(diǎn)為管徑大、直度好、壁厚大、產(chǎn)量低、耗能大、成本高、長(zhǎng)度10米左右且非定尺，另外一個(gè)重要特征是所有鋼管均有偏壁現(xiàn)象，即壁厚不均勻,偏差較大。焊接鋼管目前根據(jù)焊縫形式不同分為直縫焊接鋼管、螺旋焊接鋼管兩種，直縫焊接鋼管就焊接工藝不同又分為直縫電阻焊鋼管（ERW）和直縫埋弧焊鋼管（LSAW），執(zhí)行標(biāo)準(zhǔn)為《低壓流體輸送用焊接鋼管》(GB/T3091-2001)，焊接鋼管均是利用軋輥等模具將帶鋼延圓形漸開線逐步卷為圓形，再通過埋弧、電阻等不同焊接方式焊接成型生產(chǎn)的鋼管。該成型方式的特點(diǎn)是產(chǎn)品產(chǎn)量高、成本低、耗能小、長(zhǎng)度可以達(dá)16米且可以定尺、直徑及壁厚可良好控制，缺點(diǎn)主要是目前國內(nèi)鋼管生產(chǎn)設(shè)備技術(shù)落后，導(dǎo)致焊縫部分強(qiáng)度不足，壁厚一般國內(nèi)無法做厚。</div><p><img

class="khcont">無縫管業(yè)內(nèi)對(duì)焊管的認(rèn)知，不盡相同。相對(duì)來說，東南沿海及長(zhǎng)江中下游的無縫管企業(yè)較早接受，例如寶鋼前幾年就開始策劃上高頻直縫焊管ERW610mm機(jī)組、5m寬厚軋機(jī)和UOE大口徑直縫埋弧焊管生產(chǎn)線；武鋼集團(tuán)擬開發(fā)2250mm寬帶熱連軋機(jī)及ERW610mm機(jī)組；大冶無縫鋼管廠在研討發(fā)展方向時(shí)決定避開焊管的優(yōu)勢(shì)，不上大口徑無縫管生產(chǎn)線，生產(chǎn)發(fā)揮無縫管厚壁優(yōu)勢(shì)的產(chǎn)品；天津無縫鋼管有限公司也在研究發(fā)展焊管產(chǎn)品、熱帶生產(chǎn)線的可行性。在無縫管企業(yè)內(nèi)部，營銷部門比技術(shù)部門對(duì)焊管產(chǎn)品的認(rèn)知要早；在技術(shù)部門內(nèi)，一般技術(shù)人員與資深技術(shù)專家的感受也不盡相同。在行業(yè)外，石油系統(tǒng)比冶金系統(tǒng)認(rèn)知焊管要早。技術(shù)本身在發(fā)展，但有的快、有的慢。板、帶、棒、線材發(fā)展連鑄連軋技術(shù)快，而無縫管材就慢，因而成本居高不下。國外焊管品種隨著焊接技術(shù)的進(jìn)步快速發(fā)展，從水煤氣管發(fā)展到套管、鍋爐管。我國在1987-1992年間，大慶、勝利和塔里木油田僅從日本新日鐵就購買了規(guī)格為￠137–337mm，的油井用焊管16萬噸。
