API 650 fixed roof tanks shell-to-bottom welds

Usually, the soil resistance of the foundation should be considered before the design and construction of API 650 Fixed roof tanks. The soil endurance in the API 650 fixed roof tanks construction area plays a decisive role in the basic cost of the tank. In areas with high soil resistance, not only the cost of foundation treatment can be greatly reduced, but also the ratio of height to diameter of storage tank can be obtained. Therefore, the investment cost of the API 650 fixed roof tanks can be greatly saved in the area with large soil resistance.API 620 Crude Oil Tank Pneumatic Pressure
An air pressure equal to 1.25 times the pressure for which the vapor space is designed shall be applied to the enclosed space above the water level. In the case of a double-wall tank with an open-top inner tank, where the air pressure acts against the outer tank and the inner tank is thus not stressed by the air pressure, the inner API 650 fixed roof tanks may be emptied of water before the pneumatic pressure test begins. The test pressure shall be held for 1 hour.The interior of API 650 storage tanks to be internally lined or coated must have all edges rounded to a minimum of 3 mm radius. Internal welds must be completely seal welded, ground smooth, and free from API 650 fixed roof tanks surface porosity, pockets, and high spots. Remove weld spatter. Vendor as specified on API 650 storage tanks drawing must perform additional surface preparation.The company has always adhered to the corporate purpose of “improving benefits, creating wealth, benefiting employees, and giving back to the society”.
