At low liquid levels the roof eventually lands and a vapor space forms between the liquid surface and the roof,similar to a fixed roof tank.The support legs are usually retractable to increase the working volume of the tank.A fixed roof tank is a type of storage tank,used to store liquids,consisting of a cone- or dome-shaped roof that is Related searches for fixed roof tanks fixed legsfixed roof tanksfixed roof storage tanksSome results are removed in response to a notice of local law requirement.For more information,please see here.12345NextVideos of fixed roof tanks fixed legs Watch video on Vimeo3:16Fixed Roof Storage Tank Construction178 views fixed roof tanks fixed legs#0183;Fixed Roof Tank.In the fixed roof tank,the oil stored is not exposed.This tank type is employed for holding oil products in lower volumes than in case of tanks having floating roofs.
