Internal Floating Roof Storage Tank VS External Floating

Floating roof is the core component of floating roof storage tank,which is divided into two types external floating roof and internal floating roof.Because the flexible floating roof deck can float up and down to close to the liquid level,gas space above the liquid level can be greatly reduced,thereby greatly reducing the evaporation Internal Floating Roof Storage Tank VS External Floating Floating roof is the core component of floating roof storage tank,which is divided into two types external floating roof and internal floating roof.Because the flexible floating roof deck can float up and down to close to the liquid level,gas space above the liquid level can be greatly reduced,thereby greatly reducing the evaporation How to Control the Welding Deformation of Large Storage Viewing from Fig.1 bottom plate arrangement of 100,000m floating roof tanks Fillet Welds#179; storage tank,butt weld joint includes short weld seam and full-length weld seam,if the full-length weld seam is welded firstly,inner stress will be caused because that the rigidity will hinder the short seam welding contraction.
