The Ministry of Chemical Industry of the People's Republic of China issued WHG/T3127-1998
This standard is compiled according to the needs of the development of domestic industrial production and with reference to the standard HG5-1232-79 "Glass Tower Section".
This standard is compatible with all glass equipment standards issued after 1991, and is also compatible with other relevant standards. This standard will replace HG3-1232-79 from the date of implementation. This standard is proposed by China National Chemical Equipment Corporation. This standard is under the jurisdiction of the National Technical Committee for Standardization of Glass Equipment. The responsible drafting unit of this standard is Shanghai Pharmaceutical Design Institute of the State Pharmaceutical Administration. Zibo Chemical Equipment Factory participated in the drafting. The main drafters of this standard are Li Yijun and Ji Chuanhui. 1 Scope

3 Types, basic parameters and main dimensions
3. 1 Type
Glass tower sections are divided into three types: Type A, Type B and Type C. Type A is the tower body, Type B is the tower top, and Type C is the tower bottom specially used for sugar glass distillation containers. The connection types between A, B and C tower sections are divided into high neck flange type (Type I) and screw hole flange type (Type II). 3.2 Basic parameters and main dimensions
3.2.1 Basic parameters and main dimensions of type A are shown in Figure 1, Tables 1 to 3. 3.2.2 Basic parameters and main dimensions of type B are shown in Figure 2, Tables 1 to 3. 3.2.3 Basic parameters and main dimensions of type C are shown in Figure 3, Tables 1 to 3. Approved by the Ministry of Chemical Industry of the People's Republic of China on March 17, 1998 and implemented on October 1, 1998
