Prefabrication requirements of large vertical API 650 unanchored flat-bottom tank accessories: the prefabrication shall be deepened as far as possible in strict accordance with the requirements of construction drawings and specifications, according to the principle of convenient installation and construction, as much as possible to reduce the installation workload, especially the workload of high-altitude operation. The prefabricated accessories shall be strictly inspected to ensure the quality and make marks. In addition, effective measures should be taken to prevent deformation, damage and corrosion during storage, transportation and stacking on site.

API 650 unanchored flat-bottom tank 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.
