摘　　要：随着我国热轧卷板质量及 ERW制管水平的提高 ,生产低中压锅炉用电阻焊钢管的条件已经成熟。介绍了采用 ERW钢管再经中频感应全管体热处理生产低中压锅炉用电阻焊钢管的工艺 ,研制的焊接锅炉钢管具有良好的机械性能、冷作工艺性能 ,焊缝质量优于钢管母材 ,几何尺寸精度高 ,实物质量指标完全符合低中压锅炉用钢管的要求。Along with the hot-rolled strip quality and the level of ERW pipe manufacture improve in domestic,the factors manufacturing welded pipe for low and medium pressure boiler have possessed.It is introduced that the technology manufacturing welded pipe for low and medium pressure boiler with ERW pipe and then to be normalizing heat-treated by medium frequency induction heating.Developed welded pipe for boiler has well mechanical properties and cold-forming technology performance,the weld quality is better than the base and the size are accurate,the pipe quality fully accord with the require for the pipe of low and medium pressure boiler.
