Buoyancy Vessel full contact Internal Floating Roof

The buoyancy tank style internal floating roof use the structure of tank that the main part of the IFR is tank shape.The main part contacts the liquid fully. There is nearly no oil gas space that it could greatly reduce the evaporation loss of the liquid.

 

The whole buoyancy tank internal floating roof is made of many small buoyancy tank, so the buoyancy is much more bigger than the normal internal floating roof. The thickness of the whole IFR is less than the pontoons style IFR which improved the storage capacity of the oil tank.

 

The contacting parts of the buoyancy tank style IFR are uniform distributed so that the buoyancy is uniform and the floating of the roof is steady, which make sure of the safety working of IFR.

 

The installation of the buoyancy tank style IFR is simple, quick and the maintenance cost is low. The whole roof are combined by bolts, so there is no welding, which is especially suitable for the modified oil tank. The accessories manufacturing are molding and standardization and they could be exchanged.

 

The utilization for the tank is high

The buoyancy tank IFR are in full contact with the liquid so there is nearly no oil gas space. The whole structure thickness is less than 150mm normally, so it improve the storage space comparing with other kinds of internal floating roof, which shall improve the storage utilization.

 

The installation is simple, quick, anti-corrosion and the maintenance cost is low.

The whole internal floating roof is combined by bolts so there is no welding, which is specially suitable for modified oil tank. The accessories is moulding and standardization manufactured. Therefore this kind of internal floating roof is called “unsinkable” oil tank internal floating roof by American petroleum specialist.

 

The energy-saving effect is obvious which could be more than 98%.

The design of the internal floating roof is to make sure of the smallest oil gas space to reduce the evaporation of the liquid. The consumption reduction rate is more than 98% that could reduce the environment pollution.

 

Anti-rotation Device

The anti-rotation device could control the waggle or swing of the internal floating roof upon the liquid in case the internal floating roof has big rotation and center position shift.

 

Anti-static Device

The anti-static device is to output the static from the internal floating roof to the earth to prevent the fire accident due to the static on the internal floating roof which is caused by the loading or unloading of the liquid in the tank. The ground resistance is less than 10Ω.

 

Excellent Security

This kind of internal floating roof has prefect consideration for the outputting of static. There is no potential static danger. The products are standardization manufactured and there is no welding in the site. All of the components are combined by bolts at site. The installation and the maintenance is simple and convenient.

 

Comparing with the former buoyancy tank internal floating roof

Old buoyancy tank style internal floating roof shall be welded in the oil tank. Each welding joint is easy to corrosion. The buoyancy tank is long (normally 4 meters), so the safety factor is low that one buoyancy tank leakage may cause the inclined of the whole internal floating roof.

New buoyancy tank internal floating roof are combined together with bolts and rivets at site so there is no welding. The length of each buoyancy tank is normally 2 meters. The special buoyancy tank is less than 2 meters. The leakage for any two buoyancy tanks hasn’t any influence on the whole buoyancy, which improve the safety factor of the whole internal floating roof.
