The Direct X Primary Mechanical Shoe Seal for External Floating Roofs

The Direct x – primary mechanical shoe seal for external floating roofs  is the preferred primary seal in the industry for external floating roof tanks and is considered to be the most reliable and efficient option on the market.

A primary mechanical shoe seal for external floating roofs is a specialised type of seal that is used in storage tanks with external floating roofs. This type of seal is designed to provide a continuous, tight seal between the floating roof and the tank wall, preventing the escape of vapours and reducing the risk of liquid spills.

Featuring robust, all stainless-steel components, this seal provides a considerable effective working range, long and reliable service life, and is suitable for both installation during either in-service or out-of-service periods. The Directank Direct X Shoe Support mechanism consists of a durable single hinge configuration with sufficient structural rigidity to hold the shoe plate level throughout variable rim spaces.

The seal is created by the compression of a flexible sealing material, between the shoes or rollers and the tank wall. The shoes or rollers move with the floating roof, allowing the seal to flex and adapt to changes in the tank level and temperature. These components allow for reliable performance in even the most challenging operational conditions, including large rim gaps and tank shell inconsistencies. The mechanical shoe primary seal is the primary seal of choice for the vast majority of tank owner and operators and the best choice for reliable, continuous operation.
