API 650 aboveground oil storage tanks roof venting

The outer FRP of API 650 oil tank will not produce electrolytic corrosion with groundwater and brine. The outer FRP will not corrode with gasoline, diesel oil and leaded gasoline API 650 aboveground oil storage tanks. The leakage detector can monitor the whole process 24 hours to eliminate the potential pollution. The leakage detection system is convenient for the inspection and maintenance of API 650 oil tank, and protects the original ecological environment of soil and groundwater.

The cone slope of the completed API 650 aboveground oil storage tanks foundation is 15/1000 for the general foundation and less than 35/1000 for the soft foundation. After the foundation settlement of the storage tank is basically stable, the surface slope must be greater than eight thousandths. The edge of the tank bottom should be more than 0.3 meters higher than the surrounding ground. Above the ground, the tank bottom leakage detection tube should be drawn from the foundation sand cushion and cross the foundation ring wall or the slope protection surface. The circumferential distance should be less than 20 meters, and each API 650 aboveground oil storage tanks should have at least 4 detection tubes.

API 650 aboveground oil storage tanks test procedure
The inner tank shall be opened to the atmosphere, and a sufficient amount of water shall be added to the inner tank to balance the upward pressure against the inner tank bottom produced by the pneumatic test of the outer tank; as an alternative, the pressure between the inner and outer tanks can be equalized. API Standard 620 Air pressure shall be applied to the space enclosed by the outer tank equal to at least the design gas pressure but not exceeding a pressure that would overstress either the inner or outer tank.
