The 'seal' is an inherent requisite for the storage of a product in a floating roof tank. For many decades, the Indian Refinery Industry had to do with flawed seals. The entry of solid foam seal proved to be a solution to all earlier problems. Perfected to fulfill the most demanding service requirements and withstand severe weather conditions, solid foam seal is benchmark in durable and quality seals. Designed to fill the annular gap between the floating roof and the tank shell, the seal converts uniform pressure on the tank shell. Its flexibility allows it to compensate for irregularities in the shell, by maintaining accurate centering of the float roof. Reliable in operation, immune to internal explosion, uncomplicated in design, quick and easy to install, solid foam seal is far superior to other types of seals. Moreover, replacement of the seal is extremely safe and easy since installation and maintenance personnel need not work under the floating roof. This Primary Seal is also accompanied by an optional safety sealing accessory -- The Secondary Seal, which caters to more extreme conditions and demanding specifications.
