API Tank FeaturesAPI Tank ConstructionAPI Tank TypesAPI Tank RoofingTank MaintenanceAPI tanks can have a variety of roof types. The type of roofs include fixed-roof, external floating roof, internal floating roof tanks, and domed external floating roof. Fixed roof tanks are the most common tank type. They feature a closed and completely welded roof. Roof designs are usually cone or dome-shaped. Usually, these tanks will also have a valve used to control and maintain the internal pressure of the tank.

Oct 01, 2019The roofs help minimalize evaporation losses as the liquid levels change inside the tank. This, in turn, helps prevent fires. Lightning strikes are the culprits for most fires at storage tanks with floating roofs. Most external floating roof tank fires are rim seal fires caused by lightning. The lightning ignites the vapors which then catch fire.Floatation Test of Internal Steel Internal Floating Roof api oil storage tanks internal floating roofJun 24, 2007Floatation Test of Internal Steel Internal Floating Roof per Appendix-H.

As the level of the product fluctuates, the floating roof moves up and down with it, maintaining a sliding contact with the tank wall.
imagesInternal Floating Roofs - ErgilERGIL Internal Floating Roofs reduce emission from the storage tank. The Storage Tank remains covered as the influence of wind, rain and lightning are eliminated. This further reduces product emissions, product contamination by rainwater and the risk of rimfires. This is possible as it is designed under strictest of environmental regulations.
Perfect designed internal floating roof storage tank is the best method to control the evaporation loss of the fixed roof tank.
