A low-profile secondary seal for floating-roof storage tanks has a tip seal that is mounted on a series of segmental adapter plates connected to the shoe plates. A fabric extends between the tip seal and the floating roof. A spring presses the tip seal against the tank shell.

Spring-loaded secondary seal for floating-roof storage tank

A low-profile secondary seal for floating-roof storage tanks has a tip seal that includes a series of segmental adapter plates connected to the shoe plates. A tip seal element is mounted on the adapter plates. A fabric extends between the tip seal and the floating roof. A pusher is hinged to the floating roof, and includes a pusher bar with two ends that are disposed in a sliding arrangement against the adapter plates. A spring is connected to the pusher at an inclined angle, providing a mechanical advantage as the spring biases the pusher and pusher bar outwardly against the plates, pressing the tip seal against the tank shell.
