API standard 650 cylindrical tanks external pressure

Determination of Required Capacity
The aggregate capacities required for any vent valves, pressure-relieving valves, and/or vacuum-relieving valves to be provided should be determined as follows:
a)For thermal breathing and product movement, the rules given in API 2000 shall be followed. The required capacity as the result of the product movement into the tank API standard 650 cylindrical tanks given in API 2000, shall be multiplied by the ratio of the absolute tank pressure to atmospheric pressure (14.7 lbf/in.2 absolute).
b)For supplemental safety pressure-relieving devices to take care of extra venting capacity required in case of external fire exposure, the rules in API 2000 shall be followed.

API 650 is widely used for tanks that are designed to internal pressures of 2.5 PSI or less and store products such as crude oil, gasoline, chemicals and API standard 650 cylindrical tanks produced water. Advance Tank has extensive experience with API 650 tanks ranging in diameter from 8' - 300' for refineries, terminals, pipeline facilities and other clients.

Good news: In May 17th, 2018, the Myanmar navy's local representative visit our office and hot rolled plate production line, and sign another contract 2025 tons LR A shipbuilding steel plates API standard 650 cylindrical tanks order in our office. With the fast development in Myanmar, Myanmar navy build frigate every year. Bebon cooperated with Myanmar Navy company from from 2015. They purchased 412 ton LR AH36 ship steel plate from Bebon as trial order in 2015. After receiving the goods, they speak highly of the quality and bebon's service. After that they purchase the shipbuilding steel plate from bebon regularly.

Volatilization is the characteristic of oil. Under normal temperature and pressure, as long as the oil is in contact with air, the surface will volatilize. Through scientific analysis and summary, the causes of oil volatilization loss in API standard 650 cylindrical tanks are: natural ventilation loss, static storage loss, dynamic liquid level loss. In the use of API standard 650 cylindrical tanks, static storage loss and dynamic liquid level loss are common losses.
