The safety relief capacity ensures that the pressure in the inner container is kept within 1.2 times the design pressure
Thread Content
It can be seen that many standards stipulate that the safety relief capacity must ensure that the pressure in the inner container remains within 1.2 times the design pressure. I’m curious why the coefficient is 1.2 times Where can I find the source of the 1.2 coefficient?
Could the original poster please specify which standards contain such provisions? GB150 stipulates that when a single relief device is installed, the overpressure limit for the container shall not exceed 10% of the design pressure or 20 KPa, whichever is greater; when multiple relief devices are installed, it shall not exceed 16% of the design pressure or 30 KPa, whichever is greater. In cases where fire or unexpected external heat sources could pose a risk, the overpressure limit shall not exceed 21% of the design pressure. The design pressure plus the overpressure limit represents the highest pressure allowed inside the container.
