The operating temperature of API Std 650 floating-roof tanks
In API 650 oil storage tank, when the mixing ratio of combustible medium and air reaches a certain limit, it is easy to cause explosion. Therefore, it is necessary to add API Std 650 floating-roof tanks external floating roof to open cylindrical steel API Std 650 floating-roof tanks tank. At present, the external floating roof is most suitable for large-scale API 650 oil storage tank in China, ranging from 20000, 30000, 50000 cubic meters to 100000 cubic meters.
Usually, the wind load in the API Std 650 floating-roof tanks construction area should be considered before the tank design and construction. The wind load in the API Std 650 floating-roof tanks construction area has an impact on the stability and economy of the API Std 650 floating-roof tanks. In the area with large wind load, it is safe to design the tank as "squat". When calculating the wind force, the influence of the thickness of the insulation layer of the API Std 650 floating-roof tanks, the shape of the ladder, the platform, the pipeline and the top cover must be considered.
API Std 650 floating-roof tanks Pressure-relieving DevicesTanks shall be protected by automatic pressure-relieving devices that will prevent the pressure at the top of the tank from rising more than 10% above the maximum positive gauge pressure except as provided in API 620 standard 9.2.2.Where an additional hazard can be created by the exposure of the tank to accidental fire or another unexpected source of heat external to the tank, supplemental pressure-relieving devices shall be installed. These devices shall be capable of preventing the pressure from rising more than 20% above the maximum positive gauge pressure. A single pressure-relieving valve may be used if it satisfies the requirements of this paragraph and 9.2.1.
