A floating roof leveling and protection apparatus comprising a plurality of isolators having bases being formed of a protective material to prevent an internal metallic internal roof support leg from directly contacting a tank bottom, a body extending axially and centered therefrom, a tapered end for insertion into the roof support leg, a fluid passage, an engagement means engaging the inner perimeter of the roof support leg, and a drain and isolator spacers, whereby a user may place an isolator spacer on the isolator and insert isolators into the roof support legs of a floating roof system to adjust the height of the roof support legs to level the floating roof thereby reducing the stress placed on the floating roof as the fluid level lowers, thus preventing damage to the bottom of a tank when the fluid level is decreased and the roof support legs contact the tank's bottom.

Tank lids include a first coated substrate including a first part having a first thickness, a first elastomer coating the first part, a second coated substrate positioned adjacent to the first coated substrate, the second coated substrate including a second part having a second thickness, and a second elastomer coating the second part. A first seam can be formed between the first and second coated substrates to allow for moisture to pass between the first and second coated substrates so that moisture is allowed to seep away from the top of the tank lid.

A floating module for the reduction of losses by evaporation in aqueous-based liquids which includes two hexagonal, watertight, hollow cells and configured to accommodate an internal ballast; and a perimeter wing arranged on the horizontal axis of the floating module.

A float floating in a liquid has a spherical body having a spherical shape from which parts are cut off so as to form a regular hexagonal shape when viewed from one direction. In addition, the float is shaped so as to form a regular hexagonal shape when viewed from the above-mentioned one direction, and the floats are arranged in a honeycomb geometry to thereby reduce the contact area between the liquid and air.

A clip for securing one or more cover panels within a containment structure includes an annular portion partially-enclosing an internal space and two compressible legs adjoining opposite ends of the central portion. The clip further includes a clasp with first and second securing tabs configured to fixedly secure an object within the internal space and apply an outward force on the compressible legs.

Cover element for forming a floating covering for a liquid tank, comprising a housing (1a, 1b) having a first longitudinal coupling profile (2) and a second longitudinal coupling profile (3), as a result of which two adjacent housings (1 a, 1 b) may be coupled to one another by means of hook hinge profiles (2a, 3a) at the bottom and top coupling profiles (2b, 3b) and a locking profile (7). The end faces of the housings (1a, 1c) are provided with a transverse coupling profile (10) which is configured to cooperate with a sliding coupling profile (9) which is slid over the transverse coupling profiles of both adjacent housings. In this configuration, the cover elements are coupled to one another by a coupling construction that does not protrude beyond the main planes (4a, 4b) of the cover elements, as a result of which the surface of the entire floating roof is smooth, resulting in a substantial reduction in the accumulation of dirt etc. on the roof due to the absence of the vertical coupling flanges.
