class="ty-tips1212">以下是:柳州柳北無縫鋼管大型生產(chǎn)基地的圖文介紹 </div><div id="2udqvcc" class="khcont8">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。前者引導(dǎo)珠江鋼管公司上了JCOE及U0E大口徑直縫雙面埋弧焊管生產(chǎn)線以及其它的直縫焊管生產(chǎn)線。后者催生了石油天然氣系統(tǒng)新上了6條大口徑螺旋埋弧焊管生產(chǎn)線、青縣巨龍石油鋼管公司1條JCOE生產(chǎn)線、非石油天然氣系統(tǒng)10多條大口徑螺旋焊管生產(chǎn)線。英國核物理學(xué)家JOSEPHROTBHT在1999年“教科文組織和科學(xué)聯(lián)盟”召開的科學(xué)大會上說:“科學(xué)家是否應(yīng)該關(guān)心科學(xué)的道德以及科學(xué)對社會的影響?”從中我們應(yīng)該受到啟迪此外，企業(yè)界要思考，不要只看“風(fēng)”向，不要趕潮流，隨大流尤其在目前結(jié)構(gòu)調(diào)整時期，企業(yè)要“有進有退，有所為有所不為”。有所為，就是要以科技創(chuàng)新來擺脫企業(yè)的困境，避免同質(zhì)化引起的惡性競爭;有所不為，就是不能重復(fù)建設(shè)與歷史發(fā)展方向相悖的項目，不能參與慘烈的價格競爭，以免大傷元氣。

class="khcont">無縫管業(yè)內(nèi)對焊管的認(rèn)知，不盡相同。相對來說，東南沿海及長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機組、5m寬厚軋機和UOE大口徑直縫埋弧焊管生產(chǎn)線；武鋼集團擬開發(fā)2250mm寬帶熱連軋機及ERW610mm機組；大冶無縫鋼管廠在研討發(fā)展方向時決定避開焊管的優(yōu)勢，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。

class="khcont">在這類企業(yè)中也有一批裝備水平適中，產(chǎn)品質(zhì)量較好（可滿足相應(yīng)產(chǎn)品標(biāo)準(zhǔn)要求）的企業(yè)，它們占據(jù)了市場相當(dāng)?shù)姆蓊~。這些企業(yè)之所以能夠生存發(fā)展是他們找準(zhǔn)了市場的空間，生產(chǎn)那些大型企業(yè)不愿意生產(chǎn)或不能生產(chǎn)的小批量、多規(guī)格、多品種、薄壁產(chǎn)品，由于產(chǎn)品質(zhì)較好且生產(chǎn)成本較低，產(chǎn)品在市場上具有較強的競爭力，日前這類企業(yè)已成為無縫鋼管生產(chǎn)的重要力量。但是這類企業(yè)大部分為購坯生產(chǎn)企業(yè)，其管坯的采購和質(zhì)量沒有保證，尤其是近年礦石價格大幅度上漲，使管坯價格也在上漲。鋼管的利潤空間越來越小。另外，隨著供坯企業(yè)后繼加工線的建成，管坯的資源也會減少，未來的生產(chǎn)將會面臨嚴(yán)重的困境。上個世紀(jì)50年代初由前蘇聯(lián)援建的條自動軋管機組生產(chǎn)線在鞍鋼投產(chǎn)以來，我國已經(jīng)建成無縫鋼管機組近200臺套（這其中包括引進的設(shè)備和國內(nèi)自己研制的設(shè)備）涵蓋了當(dāng)今世界上各種機組。焊條選擇和使用是否得當(dāng)直接影響到焊縫的化學(xué)成分和使用性能，是大口徑無縫鋼管焊接準(zhǔn)備工作中很重要的一個環(huán)節(jié)。選擇合適的焊條，要綜合考慮多方面的因素，有時需要做試驗驗證，才能后確定。

class="khcont">無縫鋼管屈服強度的外在因素有:溫度、應(yīng)變速率、應(yīng)力狀態(tài)。隨著溫度的降低與應(yīng)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(yīng)變速率特別敏感,這導(dǎo)致了鋼的低溫脆化。應(yīng)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(zhì)指標(biāo),但應(yīng)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(jié)合鍵、組織、結(jié)構(gòu)、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(jié)合鍵的影響是根本性的。將制管用的板料的兩側(cè)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(zhǔn)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(yù)彎邊機：將銑邊機加工出兩邊焊接坡口的鋼板板邊進行預(yù)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(yù)焊，鋼管預(yù)焊機：將成型機成型合格的開口管坯,為內(nèi)、外焊做準(zhǔn)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。
