class="khcont">焊接鋼管在一定領(lǐng)域內(nèi)可以完全替代無縫鋼管。焊管的厚度公差高于無縫鋼管厚度公差，材料節(jié)省率高，成本低。這就是石業(yè)引進(jìn)焊管產(chǎn)品的一個主要原因。中國的無縫管、軋管產(chǎn)品都受到西方先進(jìn)焊管產(chǎn)品的挑戰(zhàn)，只有跳出單純數(shù)量擴(kuò)張的圈子，狠抓技術(shù)進(jìn)步，降低成本，產(chǎn)品向次發(fā)展才有前途。焊管發(fā)展方向的兩次重大研討會的觀點(diǎn)和影響國內(nèi)有兩次涉及焊管發(fā)展方向的重大學(xué)術(shù)討論會：一次是1998年“大中直徑長輸管線用埋弧型直縫焊接鋼管研討會”，一次是2000年“天然氣管道輸送技術(shù)及制管技術(shù)高級研討會”。前一次研討會主張“發(fā)展直縫雙面埋弧焊管取代螺旋管”，后一次研討會提出“繼續(xù)堅持油氣輸送干線鋼管以國產(chǎn)螺旋焊管為主的技術(shù)路線”。這兩次研討會的結(jié)論截然相反，對制管業(yè)有不同影響。焊管發(fā)展方向問題的再認(rèn)識但從前面敘述的焊管取代無縫管的論述來講，也只能夠是直縫焊管挑大梁而不是螺旋焊管，這就是西方為什么要大力發(fā)展直縫焊管的原因所在，也是咱們公司之所以選擇直縫焊管的原因所在。“西氣東輸”工程的實(shí)踐已經(jīng)從一個側(cè)面說明螺旋焊管可以用于輸送天然氣(一類地區(qū))；但螺旋焊管的生產(chǎn)工藝要適應(yīng)成批、穩(wěn)定地生產(chǎn)大口徑（l000mm以上)、高鋼級(X70級以上)、厚厚(14mm以上)是頗為艱難的。</div><p><img

class="khcont5">焊管“無縫化”的含義焊管和無縫管相比，的區(qū)別是焊管有一道焊縫。由于有了焊縫，使外形凸出高于母材很多，明顯地看出了“縫”;同時，內(nèi)部物理性質(zhì)上也產(chǎn)生了變化。如果能夠在這兩個方面—外在與內(nèi)在，都能使焊縫與母材相同、相近或者相等母材性能，等同于無縫，這就是“無縫化”的含義?！盁o縫化”的兩個方面如上所述，焊管無縫化包含兩個方面的內(nèi)涵，幾何無縫化，使焊縫余高盡可能小;物理無縫化，使焊縫(包括周圍熱影響區(qū))的物理性能趨于與母材一致。焊管的幾何無縫化光滑地掉焊縫處因擠壓焊接后所形成的外毛刺和內(nèi)毛刺，使焊管在幾何外形上幾乎看不到焊縫。我國和美國標(biāo)準(zhǔn)中內(nèi)毛刺的殘留高度大致上規(guī)定了兩檔精度:檔(O.127mm;第二檔0.254mm)。焊管的物理無縫化幾何無縫化處理后的焊管雖然外表上已幾乎看不到焊縫，但焊縫內(nèi)部的金相組織與母材仍有較大區(qū)別，焊縫區(qū)的機(jī)械性能較低。為此，需要經(jīng)過熱處理細(xì)化焊縫區(qū)的晶粒、去除焊接應(yīng)力，實(shí)現(xiàn)與母體金相組織、機(jī)械性能的一致化，這個過程我們稱之為焊管的物理無縫化。
