class="khcont1">經(jīng)過連續(xù)10年高達15%的快速增長，我國在無縫鋼管方面的總產(chǎn)能已近7000萬噸。中國無縫鋼管協(xié)會數(shù)據(jù)顯示，2014年我國無縫鋼管產(chǎn)量增長近10%至5765萬噸，約占全球總產(chǎn)量的一半，其中55%以上為焊管。2014年我國無縫鋼管表面消費量為5162萬噸，年增幅超8%。中國鋼鐵協(xié)會的數(shù)據(jù)顯示，我國2015年上半年共生產(chǎn)了3072萬噸無縫鋼管，比去年同期增長近20%。根據(jù)中國鋼結構協(xié)會對17家特級和29家一級鋼結構制作廠消耗的鋼材品種統(tǒng)計，目前我國鋼管消耗量占鋼結構產(chǎn)量的9%～10%。按每年2000萬噸鋼結構產(chǎn)量計算，用于工程中的結構用鋼管約為200萬噸，遠少于熱軋H型鋼，也遠低于日本、美國和歐洲的用量，這些數(shù)據(jù)表明鋼管在我國有著較大的發(fā)展空間。另外，強勁的海外需求支撐著我國無縫管的持續(xù)穩(wěn)定出口，而國內鋼廠也積極在東南亞、南美、中東、非洲等新市場開拓業(yè)務。2016年4月份鋼材產(chǎn)量為8109萬噸。4月份鋼管產(chǎn)量為605萬噸，占鋼材總產(chǎn)量的45%。4月全國無縫管產(chǎn)量235萬噸，環(huán)比減少84%同比增加8%。

class="khcont">入世后，無縫化鋼管無縫化鋼管知識解釋們需要對市場經(jīng)濟再認識，例如市場經(jīng)濟規(guī)則不僅是優(yōu)勝劣汰，企業(yè)不是追求利潤化，而是追求一種理性利潤，考慮到“雙贏”即客戶及競爭對手的贏利。因此，拋棄原有的陳舊落后的無縫鋼管和焊接鋼管，轉為生產(chǎn)高產(chǎn)量、低成本、高附加值的無縫化鋼管就成為了初期建廠的主要動機。焊接不是變形量越小越好，而是滿足使用要求的焊接就是優(yōu)異的焊接冷拔方矩管是在熱軋管的基礎上做的深加工。以熱軋管為原管，進行的二次加工！加工方法是：通過一種模具，對鋼管的口徑進行縮小，用一種拽的力，將鋼管在模具中拔過來！就是讓鋼管通過模具！這種加工方法，不需要加熱，所以稱為冷拔！冷拔的目的是將鋼管的口徑縮小！因為熱軋的工藝不能生產(chǎn)口徑太小的管子，由于其工藝的限制，太細的管子是熱軋做不出來的。只能通過冷拔的方法生產(chǎn)！比如60mm以下的管材！熱軋方矩管由于是穿孔制作而成！生產(chǎn)時只能定管子的外徑！所以管壁的厚度是有偏差的，也就是說穿孔時，做不到一點不偏正好穿到管丕的正中心！稍微有一點偏差，管子的厚度就會偏壁！冷拔方矩管由于做了一步深加工！其管壁相對于熱軋管來說是比較均勻的！偏壁較??！但還是有，因為用作冷拔的原管就有偏壁！對鍍鋅方矩管進行保管的時候是有獨立的倉庫，通風沒有雨水。應選擇在清潔干凈、排水通暢的地方，遠離產(chǎn)生有害氣體或粉塵的廠礦。

title="無縫管現(xiàn)貨直發(fā)"><br></p><div id="hxxtr1x" class="khcont1">無縫管業(yè)內對焊管的認知，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)內部，營銷部門比技術部門對焊管產(chǎn)品的認知要早；在技術部門內，一般技術人員與資深技術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)認知焊管要早。技術本身在發(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。
