 Internal Floating Roof

The internal floating roof seal system consists of float tubes joined together by clamp beams on deck skins are fitted and equipped with a continuous closure device (primary / second seal)  and between the tank shell and the floating roof edge.


The purpose of the internal floating roof seal system is to have a minimal vapor zone above the stored liquid.


This system reduces emissions and evaporative losses of storage products and the tank its subjected to less corrosive or oxidizing elements by removing the vapor zone from the fixed roof storage tanks.


Floating roof seals have been the most widely used system for storage of petroleum products.
