國內電焊鍋爐鋼管的生產(chǎn)與應用

DOMESTIC PRODUCTION AND APPLICATION OFELECTRIC WELDED BOILER STEEL TUBES

摘要: 電焊鍋爐鋼管一般指中低壓及高壓鍋爐用管、熱交換器和壓力配管,材質為碳素結構鋼和合金鋼。由于這些鋼管的尺寸精度高、表面質量好、生產(chǎn)成本低,其使用范圍不斷擴大。國外電焊鍋爐管的質量已達到無縫鋼管的等效水平。結合哈爾濱鋼管廠試制電焊鍋爐鋼管的生產(chǎn)過程,簡介了國內產(chǎn)品的應用與生產(chǎn)情況。

Abstract: Made of carbon steels and alloy steels,electric welded boiler tubes mainly include tubes for low/medium/high pressure boiler services,tubes for heat-exchanger service and tubes for pressurized piping service.Owing to advantages of this welded tube category such as high geometric accuracy,fine surface quality and cost-effectiveness,application scope of these tubes is getting wider and wider.Electric welded tubes made overseas have been even competetive with seamless steel tubes in terms of quality.Based on the trial production of electric welded boiler tubes by Harbin Steel Tube Plant,the gives us an overview of domestic production and application of this kind of welded tubes.
