新的换热器标准以国标GB151-89《钢制管壳式换热器》代替原来的JB1147-80《钢制列管式换热器技术条件》,它将设计、制造合二为一,有利于标准的贯彻。由于新旧标准差别较大,笔者将新旧标准中有关制造、检验方面的不同之处作了一个粗略的比较,见表1。另一方面,由于换热器本身的特点GB151-89《钢制管壳式换热器》与一般压力容器标准GB150-
The new standard heat exchanger GB151-89 “steel shell and tube heat exchanger” instead of the original JB1147-80 “steel tube heat exchanger technical conditions,” it will design and manufacture into one, Conducive to the implementation of the standard. Due to the large difference between old and new standards, the author of the old and new standards for manufacturing, testing the differences made a rough comparison, shown in Table 1. On the other hand, due to the characteristics of heat exchanger itself GB151-89 “steel shell and tube heat exchanger” and the general pressure vessel standard GB150-
