What are the structural features of the sealing device of the floating roof tank?
The sealing material has great flexibility, so that it can keep the tank wall and the floating tip clearance changes (B + 80mm) good seal, also can make the floating roof lifting freely without getting stuck.
The elastic sealing material is mainly composed of a rubber belt, soft foam blocks, supports, pallets and fasteners and other components, the soft foam blocks it depends on a rubber band wrapped up, filling in an annular gap between the floating roof and tank wall and form a seal.
Elastic plastic blocks wrapped in rubber belts are dipped below the storage fluid to eliminate evaporation losses, 20-30mm.
