Blowout disks are installed on pressure vessels at atmospheric pressure; what should the burst pressure be?
Atmospheric pressure vessels should be connected to the atmosphere; is it necessary to install a relief device?
At normal pressure, just adding a vent elbow or filter is sufficient; there’s no need for an explosion vent. If one is used, what material should it be made of? These are really unreasonable requirements that are frustrating
The burst pressure of a rupture disc installed on an atmospheric-pressure vessel depends on the vessel’s design parameters and application scenario. When selecting the burst pressure for a rupture disc, the following factors need to be considered: 1. The maximum allowable operating pressure of the container ； 2. Materials and properties of shrapnel ； 3. Location and quantity of blast fragments ； 4. Methods and conditions for fragment activation ； Generally, the rupture pressure of a burst disc should be slightly higher than the maximum allowable operating pressure of the container, to ensure that pressure can be released in a timely manner when excessive pressure builds up inside the container, thereby preventing explosions. The specific blasting pressure needs to be considered and determined based on the actual conditions. .

Okay! Those who were copying documents downstairs didn’t notice it; it’s slightly higher than the operating pressure but not greater than the design pressure. Whether a rupture disc needs to be installed is determined by the user based on their own actual circumstances; in some situations a rupture disc is required, but its installation is not mandatory. Equipment connected to the atmosphere is not necessarily atmospheric-pressure equipment; there is a misunderstanding regarding laws and regulations.
If the design parameters of the container are specified as follows: design pressure at atmospheric pressure, operating pressure at atmospheric pressure, then what burst pressure should be chosen for this rupture disc?
