API standard 650 welded aluminum storage tanks automatic float-level gauge

The tank wall design of API 650 oil storage tank. Since there is no ventilation pipe directly connected with the outside on the top of the API standard 650 welded aluminum storage tanks tank, the ventilation between the inside and outside of API 650 oil storage tank is realized by the respiration valve. The constant pressure of the respiration valve is 0.3kPa, so the pressure on the top of the tank is 0.3kPa.

The head of API standard 650 welded aluminum storage tanks etc. vertical oil tank is the end cover on the top of vertical oil tank. It is used to separate the oil stored in the tank and the medium outside the tank, and also used to bear the pressure on the top of the vertical oil tank. The quality of the head is closely related to the long-term safety of the API standard 650 welded aluminum storage tanks. The head surface can be divided into convex shape, cone shape and flat shape according to its shape. The oil tank head can not be disassembled after welding.

API Standard 620 tank Appendix C describes the factors involved in obtaining adequate foundations for tanks that operate at atmospheric temperature. The foundations for refrigerated tanks are complicated because of the thermal movement of the tank, the insulation required for the bottom, the effects of foundation freezing and possible frost heaving, and the anchorage required to resist uplift. The services of a qualified foundation engineer are essential. Experience with tanks in the area may provide sufficient data, but normally a thorough investigation, including soil tests, would be required for proper design of the foundation.
