How should this device be classified?

This post was last edited by YeTangZhangShang on 2020-7-13 at 09:56. Atmospheric pressure; volume: 0.002 m³. It contains a liquid with extremely hazardous properties. Neither the pressure nor the volume falls within the scope of application of the Pressure Vessels Regulations; yet NBT47001 \"Atmospheric Pressure Vessels\" specifies that such vessels cannot be used to hold extremely or highly hazardous media. How should this situation be handled? Are pressure vessels calculated as atmospheric pressure vessels and therefore not subject to regulation? How is the design pressure determined? How to choose a head (the minimum size for standard heads is 300)?

Designed and manufactured in accordance with GB150

No classification; designed in accordance with GB/T150

So how is the design pressure determined? What about the test pressure and non-destructive testing?

Check whether there are any requirements regarding the pressure of the process system and system pressure testing; if no such requirements exist, determine it in accordance with GB150. The requirement for the inspection ratio in non-destructive testing to be 150 is also specified.

According to GB150, should the design pressure be set at 0.1? Additionally, a airtightness test is required, along with 100% non-destructive testing?

The attribute tables of the containers are designed and manufactured for normal pressure, while the testing is carried out at 150 pressure

Find a glass bottle for holding chemicals in the laboratory.

What about the other attributes? For example, a head with DN100, design pressure, and so on

Pressure vessels are designed and manufactured without supervision or inspection.

Design pressure: It should be based on the requirements of the device itself; in other words, it’s a device that isn’t classified as a 150-series device, but is still designed, manufactured, and tested according to 150-series standards. Does that make sense?
