Apr 07,2021·How Floating Roof Storage Tanks Work.As the name suggests,floating roofs float on top of a product,such as crude oil,in a storage tank.As the level of the product fluctuates,the floating roof moves up and down with it,maintaining a sliding contact with the tank wall.The objectives are to prevent evaporation loss or minimize evaporation Images of Bulgaria Single Plate Floating Roof Oil Tank Building imagesFixed roofs of aboveground steel tanksAccording to API650 roof plates could not be jointed to roof supporting structures.Plates have to be welded only to top angle.In this reason is certainly that joint between roof and shell is frangible.This type of joint is easy to tear in case of explosion in the tank.Supported cone roofs are not widespread in Bulgaria,especially for tanks Mass storage tanks-Honggang industrial solutionsThe floating roof is quite suitable for high value liquid.Horizontal Tank.The horizontal tank can be built above or under the ground.Horizontal tanks are usually made of steel,steel with fiberglass overlay or fiberglass-reinforced polyester.Usually these are some tanks for chemical liquid storage.The horizontal tanks can be made on site or made in factory and transported in pack.The underground tanks will have anti-corrosion treatment to prevent corrosion of the tank.Pressure Tank
