Double deck type external floating roofs anchored liquid storage tanks

roof tank design - New York Engineers

2.External Floating Roof Tanks External floating roof tanks have a floating roof which covers the liquid inside.The floating roof rests on the liquid and floats up and down as the level changes.External floating roof tanks are generally made of steel and only has a floating roofStudy and Analysis of Storage Tank Hazards and its The internal roof floats on pontoons or has a double deck for floatation over the liquid surface (Figure 3).These tanks will generally be found in service conditions where high volatility (Low Flash Point) or toxic liquids are stored.In a fixed roof tank without a floating cover,the liquid surface is in direct contact with the airspace above it.Storage tanks,Fixed-roof tanks,Floating roof tanks The internal floating roof rises and falls with the liquid level.Domed External Floating Roof Tank.Domed external floating roof tanks have the heavier type of deck used in external floating roof tanks as well as a fixed roof at the top of the shell like internal floating roof tanks.
