Tank Seal
It is used to prevent the loss of stored hydrocarborn product in depository in oil refining company, It is an important product to save resource and protect environment.
Oil Tank Seal has the advantages for preventing evaporation loss generated in the process to store volatile liquid, preventing fire, and securing safety.
Oil Tank Seal is applied to floating roof, which rises or falls depending on liquid inflow or outflow. It is the system to prevent foreign material into liquid and minimize the space between liquid and roof to restrict evaporation. The company’s product can decrease more than 94% of evaporation loss with specialized design.
Oil Tank seal provides supplementary insulation function so it is possible to save operation cost and decrease potential danger by maintaining low pressure. It prevents air infiltration via the top of floating roof.
It is used to prevent dissolution of oxygen in liquid depository. As a result. It prevents corrosion of high-cost depository and pipe, protects facility and maintains purity of stored solution.
