class="khcont">從行業(yè)現(xiàn)狀可知，我國長期以來走無縫鋼管發(fā)展之路，造就了一個“無縫鋼管大國”，在技術(shù)思路上似乎走了彎路，進(jìn)人了誤區(qū)?！肮艿拦こ探ㄔO(shè)所用的管材，經(jīng)過數(shù)年的努力，從無縫，到螺旋縫，到中直縫，走過了漫長的道路”，“大量使用無縫鋼管，甚至大量進(jìn)口，外國人對此都表示難以理解”。為什么外國人對中國“大量使用無縫管難以理解”就是因為國外早已用焊管來取代大部份用途的無縫管。中國本來是沿襲無縫鋼管發(fā)展的模式，而70年代后已經(jīng)將無縫管的比例下調(diào)到44％,可為什么我國一直照老路走下去呢?頗令人反思究其原因主要是舊計劃經(jīng)濟(jì)體制不計成本，不求效益，思想禁錮、慣性思維、缺乏創(chuàng)新意識。不見曾經(jīng)有人對焊管技術(shù)不理解、不放心，對焊管“無縫化”這個術(shù)語采取令，實際上焊管技術(shù)在不斷發(fā)展，“無縫化”的程度在不斷提高。中國鋼管業(yè)的重大變化發(fā)生在改革開放以后。隨著的解體、“冷戰(zhàn)”局面的告終，西方先進(jìn)技術(shù)源源不斷傳人中國，比較先進(jìn)的直縫焊管技術(shù)在80年代至90年代陸續(xù)登陸中國，石油石化行業(yè)率先推界到管道應(yīng)用。原中國石油天然氣總公司于1991年3月11日以(91)中油物字第173號文下發(fā)了《關(guān)于推廣使用無縫化鋼管替代無縫鋼管的通知》的紅頭文件，用行政方式來加以推廣。

class="khcont5">其中過熱區(qū)組織由于焊接的溫度在1100℃以上，奧氏體晶粒急劇長大，冷卻后晶粒粗大，在一定的化學(xué)成分和冷速條件下還會形成硬而脆的晶相。此外，由于溫度梯度的存在也會產(chǎn)生焊接應(yīng)力。其綜合結(jié)果，焊縫區(qū)的綜合機(jī)械性能比母材低。焊管物理無縫化就是通過焊縫熱處理，達(dá)到應(yīng)力、均化和細(xì)化組織、提高焊接熱影響區(qū)綜合機(jī)械性能的目的，而其根本目的是應(yīng)力。焊管物理無縫化處理主要有兩種方法:焊縫局部處理法和整體加熱處理法。由于主要是焊縫熱影響區(qū)有硬化現(xiàn)象、機(jī)械性能低下，所以我們首先應(yīng)考慮對焊縫熱影響區(qū)進(jìn)行局部處理。焊縫局部常化處理的方法是采用中頻感應(yīng)加熱裝置將焊縫熱影響區(qū)加熱至約927。9℃，然后空冷至538℃以下，隨后水冷。對于直徑較小的鋼管，采用管坯整體加熱方式處理，然后空冷或在帶有可控氣氛的冷卻室中冷卻。以上講的是高頻直縫焊管的無縫化技術(shù)。至于大口徑直縫埋弧焊管其用途上要是作為輸送管，在無縫化方面的要求就有所區(qū)別，在焊縫上由焊接工藝控制余高，再用擴(kuò)徑方法(機(jī)械擴(kuò)徑或水壓擴(kuò)徑)來應(yīng)力。無縫化鋼管無縫化鋼管知識解釋油專用管、管線管、標(biāo)準(zhǔn)管、機(jī)械管、結(jié)構(gòu)管、承壓管和不銹鋼管等7個方面的各占比例的對照，說明焊管用量在比例上大大超過了無縫管，在前面已談到美國高壓鍋爐管都用上了焊管，其焊管發(fā)展水平之高就可想而知了。
