Drain systems are of vital importance to the integrity of external floating roof tanks. As these are open tanks having a floating roof on top of the product stored they do collect and accumulate significant quantities of rainwater. This rainwater is than disposed off through product submerged drain systems, that have to ensure adequate rainwater run-off while also allowing the floating roof to move up and down and representing a tight system, not allowing product to leak into the drain line and run out from the tank (drain valve normally open) or to run on top of the floating roof (drain valve normally closed).
