摘要
本文主要介绍了该台设备壳体长、内径小、壁厚、折流环制造复杂及装配精度高的工艺技术,并介绍了该设备在整体热处理过程中怎样避免由于温差应力过大而使管子管板的角焊缝产生裂纹的方法。
This paper introduces a manufacturing techinque for heat exchanger with longer shell,small- er inside diameter,larger thichness,more complex fabracation of the baffles and more accurate assembly.And this article also introduces the methods to prevent fillet weld between tube and tube sheet from cracking,due to large stress for temperature differential during the heat treatment of heat exchanger.
