JB/T 4735 怪为两个部分：
-- JB/T 4735.1 钢制焊接常压容器；
-- JB/T 4735.2 固体料仓。
本部分为JB/T 4735 的第2 部分，代替JB/T 4735-1997 中 圆筒形料仓” 内容。
本部分与JB/T 4735-1997 相比，主要变化如下：
-- 修订了料仓的设计压力、设计温度、公称容积等的适用范围；
-- 将料仓的安全系数由2.5 修订为2.4；
-- 增加了磨蚀裕量的规定；
-- 扩大了Q235 系列材料的使用范围；
-- 将料仓的设计计算方法由 詹森（Janssen）方法” 修改为 赖姆伯特（Reimebert）方法” ；
-- 撤消了图14-1d 锥顶悬挂式” 的结构；
-- 修改了14.19 环形支座” 的内容；
-- 增加铝制料仓的内容，包括铝材（第5 章的5.75.11）、制造（第8 章）；
-- 将原标准中的 制造、检验与验收” 分为：第7 章 钢制料仓的制造、检验与验收” 和
第8 章 铝制料仓的制造、检验与验收” 两个部分；
-- 增加了附录A 固体料仓的结构” 。
本部分的附录A 为资料性附录。
本部分由全国锅炉压力容器标准化技术委员会（SAC/TC 262）提出并归口。
