關(guān)于復(fù)合或貼合鋼管發(fā)展中若干問(wèn)題的考查和探討(上)

Review and Discussion on Issues about Development of Clad or Lined Steel Tube(Part I)

摘要: 介紹了冶金復(fù)合鋼管與機(jī)械貼合鋼管的本質(zhì)差異及其發(fā)展態(tài)勢(shì)；探討了內(nèi)壁直接堆焊CRA復(fù)合鋼管方法在發(fā)展中存在的問(wèn)題；提出了優(yōu)化復(fù)合或貼合鋼管焊縫質(zhì)量的方法，以及確保貼合鋼管制造和應(yīng)用質(zhì)量的方法；對(duì)比分析了國(guó)內(nèi)外復(fù)合鋼板（管）熱處理標(biāo)準(zhǔn)的差異，討論了復(fù)合鋼板的鍵合質(zhì)量檢驗(yàn)方法及其標(biāo)準(zhǔn)；簡(jiǎn)要討論了復(fù)合鋼管的選材依據(jù)。

Abstract: Elaborated here in the paper are the essential difference between the metallurgically-clad steel pipe and the mechanically-lined steel pipe, and the development situations thereof.Also discussed are the problems as staying with application of the CRA clad pipe process in the development.Further proposed are the method for optimization of weld quality of the clad pipe or the lined pipe, and the methods for assuring of the manufacture and application quality of the lined steel pipe.Comparatively analyzed are differences between applicable foreign and domestic standards for heat treatment of the clad steel plate(pipe).And finally discussed are the method and standard for inspection of the bonding quality of the clad steel plate, and the basis for determining material of the clad steel pipe.
