Compared with the external floating roof stainless steel storage tanks for sale, the internal floating roof stainless steel storage tanks for sale has the advantages of protecting the floating roof from wind and rain and ensuring the quality of liquid storage under the floating roof. At the same time, because the inner floating plate is in the tank, there is no rain and snow load, so the central drainage pipe and escalator and other accessories on the floating plate can be omitted. In addition, under the same sealing conditions, the internal floating roof tank can further reduce the evaporation loss compared with the external floating roof tank.

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 stainless steel storage tanks for sale may be emptied of water before the pneumatic pressure test begins. The test pressure shall be held for 1 hour.

For floating roof API 650 tanks, the net working capacity is the liquid volume contained between the stainless steel storage tanks for sale maximum operating level (300 mm below rim for metallic type seals and 600 mm below rim for fabric type seals) and the minimum operating level (API 650 tanks roof supports clearing the tank bottom by 25 mm while set at the operating position).

In December of 2018, our regular India customer sent us an inquiry for stainless steel storage tanks for sale pipe.
