有关规范对固定管板式换热器设计中管子、壳体应力规定的分析

Fixed Tubesheet Exchangers Stipulated by Some Relevant Codes

本文在前二文的基础上分析了TEMA、ASMEⅧ—1、CODAP、GB151—89、JB4732—95等规范对固定管板式换热器设计中管子和壳体应力的计算公式,再次指出的危险工况下管子和壳体应力在固定管板式换热器设计中的重要意义。

Based on the papers[1] and[2], the equations, given in TEMA, ASME VIII - 1, CODAP, GB 151 - 89 and JG4732- 95, for calculating the stresses of the tubes and the shell in the fixed tubesheet exchangers were analyzed. It is pointed out again that the stresses of the tubes and the shell in the dangerous operating conditions have the significant meaning.
