摘　　要：从换热器的总传热系数及换热管厚度计算两个方面阐述了标准中为什么规定换热管不考虑腐蚀裕量;指出换热管考虑腐蚀裕量的方式与其它受压元件不同;总结了换热管考虑腐蚀裕量的几个方面。Why not to take into account corrosion allowance of the heat exchanger tube in the standard was discussed from two aspects of overall heat transfer coefficient and heat exchanger tube thickness calculation. It＇s pointed out that means to take into account corrosion allowance of the heat exchanger tube is different from other pressure parts. Several factors to take into account corrosion allowance of the heat exchanger tube were also presented.
