A573 Gr 450 plates API 650 welded steel storage tanks
API 650 petroleum storage tank body design is mainly the design of tank bottom, API 650 welded steel storage tanks tank top and tank wall, and the design of tank wall is particularly important. As the main pressure bearing part of API 650 petroleum storage tank, the tank wall bears loads including liquid pressure, wind pressure, seismic load, opening stress, etc. The calculation of such loads is explained in detail in various API 650 welded steel storage tanks storage tank design standards. But in addition, the API 650 petroleum storage tank wall also bears the push-pull force and torque of the connected pipeline.
According to the structure type of floating roof, floating roof API 650 welded steel storage tanks can be divided into internal floating roof tank and external floating roof storage tank. The internal floating roof tank is a floating roof tank with tank roof. The top is the combination of dome roof and floating roof, the external is dome roof, and the internal is floating roof. There is no vault on the top of the External floating roof tank, only a top plate floating with the storage liquid. The common feature of the inner floating roof tank and the outer floating roof tank is that both of them can reduce the evaporation loss of the storage liquid.
API 650 welded steel 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.
Our company will set up a full-time service engineer for the project, who is responsible for the interface and coordination of technical support and after-sales service of the API 650 welded steel storage tanks project. In response process of customer service center, in case of technical support and after-sales service demand, the user shall contact the full-time engineer of API 650 welded steel storage tanks customer service center, and the technical personnel will give corresponding answers and on-site treatment according to the needs of users.
As we all know, steel pipes occupy more space in the process of transportation. If there is no good way of packing, the transportation cost for steel pipes will be a big expense. In view of this characteristic, our company is ingenious and adopts the nest package method to solve this problem perfectly. The premise of the nest package is that the diameters of the steel pipes are different, and the small diameter pipe is inserted in the large diameter pipe. This not only saves the volume, but also saves the transportation cost. It also reduces the loading and unloading workload by half, saves precious time, and enables customers to receive goods earlier.
