BlueSky® Primary & Secondary Sealing system

An external floating roof's primary rim seal acts as the first barrier against emission in the rim area. Furthermore, it is a safety device that reduces the risk of combustible vapors in this area. Secondary seal designed to effectively prevent rim fires, Protect the stored product from contamination and extend the life of the primary seal. Therefore, it is essential that the sealing system is designed and assembled correctly.

Storage tank primary and secondary seal.

Extensive considerations one responsibility

Leveraging decades of engineering expertise and real-life practical experience. We have engineered our floating roof tank sealing system to provide excellent sealing properties with high product compatibility.

Qualitech BlueSky® sealing systems are custom designed in collaboration with Carl Spaeter™, ensuring outstanding suitability along with Cutting Edge Engineering.

Qualitech BlueSky® sealing systems are designed for optimum emission reduction and demonstrate a calculated emission reduction efficiency of at least 98% as per API chapter 19 sec.2 latest edition

Qualitech BlueSky® sealing systems have been designed to demonstrate safe operation and working capacity under rim spaces ranging from 90 mm to 425 mm. The pantograph has a built-in coil spring of 40 N pressure force. Along with Normally-Open-Type configuration, shoe plates maintain level position under all variations in rim space.

Qualitech BlueSky® sealing systems are designed for consistent shoe to shell pressure (Min 20 Kg/M2) to enable centering of the floating roof. Each shoe plate has a minimum of 14 pressure point.

Sealing effectiveness is determined by measuring the primary and secondary seal gaps separately and calculating the gap measurements and gap ratio as per EPA 40 CFR-sec 63-1063 and as per EFS BREF-sec 5.1.1.2.
