API 650 aboveground oil storage tanks filler metal

In Appendix E to API 650 oil storage tank, the maximum values of inertia force, pulse pressure and convection pressure are superimposed, and tend to be conservative.In GB50341, only pulse pressure is calculated for API 650 aboveground oil storage tanks tanks below 5000 m.

API 650 aboveground oil 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.

The cost of mechanical cleaning for vertical storage tank, API 650 aboveground oil storage tanks is low, almost all oil can be recovered, and the quality of recovered oil is high. The cost of manual cleaning for vertical storage tank, API 650 aboveground oil storage tanks is high, the oil can not be recovered completely, and the quality of recovered oil is low. The mechanical cleaning of API 650 aboveground oil storage tanks adopts fully enclosed operation, and separates oil, water and oil sand. There is no direct discharge of oily sewage and waste gas, which will not pollute the environment.
