This standard is based on the GB/9019-1R nominal diameter of pressure vessel that has been implemented, and summarizes the application of pressure vessels in various industries over the years. This standard is formulated based on the main principles of enrichment and improvement. This standard has the following changes: --- The scope of application of the standard includes pressure vessels. --- Two diameter grades of 85mm and 5cm/1 are added. The nominal diameter of K vessels above LN1000 increases by 100mm for each additional diameter. This standard shall replace CB 9019-1588 from the date of implementation. The standard is proposed by the National Technical Committee for Standardization of Pressure Vessels, and is under the jurisdiction of the National Technical Committee for Standardization of Pressure Vessels. This standard is drafted by China National Chemical Engineering Corporation. The main drafters of this standard are Fei Zuo and Wen Bing. This standard was first issued in April 2018.

Nominal diameter of pressure vessels
Nounioal diameter of pressure vessels
This standard specifies the nominal diameter series size of the container. This standard is applicable to small pressure vessels and pressure vessels with pressure gauges. This standard is not applicable to gas cylinders. 2.2 The nominal diameter of pressure vessels is expressed by the diameter of the pressure vessel, which is divided into two series. 2.1 The nominal diameter of pressure vessels based on the internal diameter is selected from the current specifications in Table 1. At this time, the nominal diameter of the pressure vessel refers to the internal diameter of the container. Table 1
marking example, the pressure vessel with an internal diameter of 1300mm is shown in the figure. Nominal diameter of pressure vessel, nominal diameter N12UIGB/T9m19--21
Note that this standard does not limit the use of boxes with a weight of more than 6600. 2.2 The nominal diameter of the positive pressure vessel based on the outer weight is 5G0F
The nominal diameter of the pressure vessel is selected according to the provisions of Table 2. At this time, the nominal diameter of the repulsive pressure vessel refers to the outer diameter of the container. Table 2
Example: The nominal diameter of the pressure vessel with an outer diameter of 155r is used as a simplified pipe: Nominal diameter DN159GR/T9019: ·2007 National Quality and Technical Supervision Bureau 2001-02-13 approved with 377bZxz.net
