Floating roof requirements and advantages of storage containers
Apr 01, 2019

During the operation, the storage container is mainly composed of a floating roof floating on the surface of the medium and a vertical cylindrical tank wall. The floating roof rises and falls with the increase or decrease of the medium storage in the tank, and the outer edge of the floating roof and the tank wall There is an annular sealing device between the media in the tank, which is always covered directly by the inner floating roof to reduce the evaporation of the medium.

1. Tank bottom of the storage container: The volume of the floating roof tank is generally large, and the bottom plate of the floating roof adopts an arcuate edge plate.

2. The tank wall of the storage container: The tank wall of the storage container is directly used in the straight tank wall, and the welded joint should be smoothed to ensure the inner surface is flat. The upper part of the floating roof tank is open. In order to increase the rigidity of the wall, the windshield and the reinforcement ring should be set at the top of the tank wall according to the wind load in the area.

3. Floating roof: The floating roof is divided into a single disc floating roof, a double disc floating roof and a float floating roof.

4. Single-disc floating roof: The annular floating vessel is composed of several independent compartments, and the inner side of the ring is a single-plate top plate. The bottom of the single plate top is provided with multiple round steel ring reinforcements. Its advantages are low cost and good maintenance.

Double disc floating roof: consists of upper plate, lower plate and cabin edge plate, separated by radial partition and ring partition into several independent annular chambers. The advantage is that the buoyancy is large and the drainage effect is
