API standard 650 unanchored flat-bottom tank maximum design pressure

Application scope of API 650 petroleum storage tank:
1. API standard 650 unanchored flat-bottom tank Working pressure: atmospheric storage tank;
2. API 650 petroleum storage tank working temperature: -30℃～150℃;
3. API 650 petroleum storage tank liquid medium: various oil products, including naphtha, gasoline, diesel, kerosene, crude oil, fuel oil, heavy oil, benzene, xylene, methanol, ethanol;
4. API 650 petroleum storage tank volume: current design considerations generally do not exceed 10,000 cubic meters.

The hardness of the welds contacting these environments, including the heat-affected zones, shall be considered. The weld metal and adjacent heat-affected zone often contain a zone of hardness that is well in excess of a value of 22 on the Rockwell C scale and could be expected to be more susceptible to cracking than would unwelded metal. Any hardness criteria shall be a matter of agreement between the Purchaser and the API standard 650 unanchored flat-bottom tank manufacturer and shall be based on an evaluation of the expected hydrogen sulfide concentration in the product, the possibility of moisture being present on the inside metal surface, and the strength and hardness characteristics of base metal and weld metal.

API standard 650 unanchored flat-bottom tank Oil measuring hole: The oil measuring hole is used to measure the height, temperature and sampling of the oil stored in the tank, and is installed near the tank top platform. API standard 650 unanchored flat-bottom tank Fire extinguisher: The fire extinguisher (also known as the flame arrestor) of the oil tank is composed of a fire box, a copper wire mesh and an aluminum partition. It is installed under the breathing valve or safety valve to prevent sparks and air from entering the inside of the tank through the breathing valve or safety valve and causing accidents.
