class="khcont5">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。隨后我國在大慶和遼河油田用日本提供的焊接套管建設過試驗油井。這些事實證明，只要有先進的生產工藝和質量控制手段，焊接鋼管在一定領域內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)引進焊管產品的一個主要原因。中國的無縫管、軋管產品都受到西方先進焊管產品的挑戰(zhàn)，只有跳出單純數(shù)量擴張的圈子，狠抓技術進步，降低成本，產品向次發(fā)展才有前途。因此，在20世紀末21世紀初，國內冶金行業(yè)無縫化鋼管技術的研究應運而生。無縫鋼管關于焊管發(fā)展方向的兩次重大研討會的觀點和影響國內有兩次涉及焊管發(fā)展方向的重大學術討論會：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及制管技術高級研討會”。

class="khcont">關于大口徑涂塑鋼管的外表預處理量量應達到GB/T8923尺度中劃定的Sa2?級要供。可根據不同的需要涂敷聚氯乙烯、聚乙烯、環(huán)氧樹脂等各種不同性能的塑料涂層，附著力好，抗腐蝕性強，可耐強酸、強堿及其它化學腐蝕，、不銹蝕、耐磨、耐沖擊、耐滲透性強，管道表面光滑，不粘附任何物質，能降低輸送時的阻力，提高流量及輸送效率，減少輸送壓力損失。涂層中無溶劑，無可滲出物質，因而不會污染所輸送的介質，從而保證流體的純潔度和衛(wèi)生性，在-40℃到＋80℃范圍可冷熱循環(huán)交替使用，不老化、不龜裂，因而可以在寒冷地帶等苛刻的環(huán)境下使用。錨紋淡度達到50μm―75μm。外表預處理功的鋼管應在6h內進行涂塑，超功6h后應從新進行處理。大口徑無縫鋼管彈性變形大，施工中操作不當易使大口徑鋼管產生較大豎向變形以至失穩(wěn)，嚴重影響使用功能.鋼管作為無縫鋼管鋼鐵產品的重要組成部分，在國民經濟發(fā)展中發(fā)揮著重大作用。目前全世界鋼管行業(yè)發(fā)展的總趨勢是：焊接鋼管產量增長速度要快于無縫鋼管的增長速度;焊接鋼管產量在比例上要遠遠大于無縫鋼管;在各個領域爭奪無縫管的市場;熱鍍鋅管在焊接鋼管管型中，ERW焊接鋼管在產量上占主導地位，而且在油氣長輸管線、城市燃氣管線的使用領域內向直縫埋弧焊管和螺旋埋弧焊管爭奪市場。
