API 650 liquid-storage tanks seismic use group i
Lateral braces between outer bay rafters must be provided if asymmetrical structural shapes are used for rafters and if the API 650 liquid-storage tanks API 650 tanks are located in areas subject to earthquakes. The bracing must be adequately sized for the seismic zone specified.
In the process of API 650 liquid-storage tanks steel transportation, enterprises often use railway transportation, highway transportation, water transportation and other ways to transport. According to the cargo owner's requirements on the timeliness of the goods and the different transportation routes, our company will choose API 650 liquid-storage tanks different modes of transportation. According to the specific needs of customers, or specify the mode of transportation.
API 650 liquid-storage tanks Liquid Relief ValvesA tank, which is likely to operate completely filled with liquid, shall be equipped with one or more liquid relief valves at the top of the roof, unless otherwise protected against overpressure. When such valves are, in effect, supplementary relief devices, they may be set at a pressure not greater than 1.25 times the design pressure. Because the relief valve at the pump, which provides the inflow of liquid to the tank, is set at a pressure greater than 1.25 times the design pressure of any tank that may be built under these rules, provision should be made for preventing overfilling of the tank by a self-closing float valve, by some practicable pilot-valve control, or by any other proven device.
Atmospheric API 650 liquid-storage tanks refer to storage tanks whose gas or vapor pressure is greater than -0.02MPa but less than 0.1MPa. Metal atmospheric storage tanks made of steel welded on the ground are often used to store petroleum, chemical and other similar liquids. Atmospheric API 650 liquid-storage tanks usually have a connecting pipe directly connected to the atmosphere, so that the operating pressure in the storage tank does not exceed the design pressure at all times.
