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(jiān)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?！拔鳉鈻|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
