ASTM A333 pipe API 650 mechanically-anchored tanks
API 650 mechanically-anchored tanks, Vertical oil storage tank is an important equipment for many enterprises to carry out production, which provides important support and help for the storage of many reagents. Vertical storage tank is generally used as atmospheric pressure vessel. Advantages: the filling rate of cylindrical structure is second to that of spherical tank, and the largest volume of the storage tank can be made into tens of thousands of cubic meters. The structure is simple and the construction requirements are relatively low.
Pressure Setting of Safety DevicesExcept as provided in API 620 tank 9.5 for certain liquid relief valves, the pressure setting of a pressure-relieving device shall in no case exceed the maximum pressure that can exist at the level where the device is located when the pressure at the top of the tank equals the nominal pressure rating for the tank (see API 620 tank 5.3.1) and the liquid contained in the tank API 650 mechanically-anchored tanks is at the maximum design level.Vacuum-relieving devices shall be set to open at such a pressure or partial vacuum that the partial vacuum in the tank cannot exceed that for which the tank is designed when the inflow of air (or other gas or vapor) through the device is at its maximum specified rate.
Floating roof is the key component of floating roof API 650 storage tank, which can be divided into external floating roof and internal API 650 mechanically-anchored tanks floating roof. The internal floating roof has a fixed top cover above the floating roof, which can prevent the floating roof from being exposed to wind and rain, and ensure the quality of oil stored under API 650 storage tank.
