How should the design pressure of a storage tank equipped with a breathing valve be determined? Are there any guidelines to refer to?
It has a breathing valve that leads to the atmosphere, which indicates that it is a atmospheric-pressure storage tank and not a pressure vessel; a design pressure of less than 0.1 MPaG is sufficient.
So how should the specific value of the design pressure for this storage tank be determined? If the pressure of the breather valve is known, are there any relevant formulas or regulations?
The design pressure is usually a little higher than the pressure of the breather valve. For example, if the positive pressure of the breathing valve is 1760 Pa, the design pressure of the storage tank is set at 2000 Pa.
First, the design pressure is determined based on the maximum operating pressure; generally, storage tanks with a pressure of less than 6.9 KPa are considered atmospheric pressure tanks. The maximum opening pressure of the breathing valve is less than the design pressure value.
The priorities are reversed. Should the breathing valve be chosen based on the container, or should the container be chosen based on the breathing valve? It’s not feasible for liberal arts students to succeed without understanding the principles
Reference can be made to SHT-2007 \"Code for Design of Storage Areas in Petrochemical Storage and Transportation Systems\", as well as Sinopec’s document [2016] No. 127 \"Guidelines on the Implementation Plans for Oil and Gas Connection Processes in Petrochemical Storage Areas and Safety Measures\"
The installation of safety accessories for storage tanks is detailed in the table below
Sir, the image is not clear. May I ask which standard this image follows?
