class="khcont5">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”，在技術思路上似乎走了彎路，進人了誤區(qū)?！肮艿拦こ探ㄔO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)有人對焊管技術不理解、不放心，對焊管“無縫化”這個術語采取令，實際上焊管技術在不斷發(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，西方先進技術源源不斷傳人中國，比較先進的直縫焊管技術在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="khcont">無縫鋼管屈服強度的外在因素有:溫度、應變速率、應力狀態(tài)。隨著溫度的降低與應變速率的增高,材料的屈服強度升高,尤其是體心立方金屬對溫度和應變速率特別敏感,這導致了鋼的低溫脆化。應力狀態(tài)的影響也很重要。雖然屈服強度是反映材料的內(nèi)在性能的一個本質指標,但應力狀態(tài)不同,屈服強度值也不同?！　∮绊憻o縫鋼管屈服強度的內(nèi)在因素有:結合鍵、組織、結構、原子本性。如將金屬的屈服強度與陶瓷、高分子材料比較可看出結合鍵的影響是根本性的。將制管用的板料的兩側面進行機械加工,并使兩板邊的平行度達到規(guī)定的公差范圍內(nèi)，為制造出高精度的鋼管做準備。使鋼板板邊具有鋼板將成型鋼管半徑相等曲率半徑，鋼板預彎邊機：將銑邊機加工出兩邊焊接坡口的鋼板板邊進行預彎。防止成型機成型成型鋼管中產(chǎn)生過長的直邊，保證鋼板的圓度。全自動鋼管成型機：完成對各種金屬板料的彎曲成型。進行進一步的合縫和預焊，鋼管預焊機：將成型機成型合格的開口管坯,為內(nèi)、外焊做準備。焊接小車運送工件沿軌道行走，雙絲內(nèi)焊機：用于對大口徑直縫鋼管進行自動埋弧焊接,配合主機實現(xiàn)對工件的焊接。

class="khcont">從去年至今，無縫管業(yè)陷入了一種“去產(chǎn)能焦慮”之中。今年一季度，鋼價瘋漲氛圍下帶動一批鋼企復產(chǎn)，以建龍無縫管為代表的一批大小鋼廠重燃高爐，將產(chǎn)能和庫存又逐步推向高位。其中，5月份粗鋼日均產(chǎn)量234萬噸，創(chuàng)出歷史新高。一時間，無縫管去產(chǎn)能之路更加道阻且長。從市場化去產(chǎn)能的角度來看，記者采訪的多位業(yè)界人士達成的共識是，企業(yè)只有在真正長期虧損的情況下才能實現(xiàn)去產(chǎn)能。有業(yè)內(nèi)人士指出，按照經(jīng)驗，當鋼企在連續(xù)2到3個月噸鋼虧損200至300元的條件下，才有可能關停高爐。而上半年的回暖行情一定程度上延緩了企業(yè)主動淘汰產(chǎn)能、退出市場的進程。事實上，無縫管去產(chǎn)能阻力重重的背后折射出經(jīng)濟學上的“囚徒困境”理論：盡管幾乎所有無縫管企業(yè)都明白只有一起去產(chǎn)能才能救這個行業(yè)，但很多時候企業(yè)都希望別人先減產(chǎn)，自己則是堅持到后的那一家。這正反映了個人的選擇有時并非團體的選擇。事實上，勞動生產(chǎn)率低、經(jīng)營效率不足是早一批建立的無縫管集團的通病。在為新中國成立之初的無縫管工業(yè)作貢獻時，它們也背負了特殊國情和時代背景下產(chǎn)生的歷史負擔。
