The internal floating roof seal system consists of the float tubes joined with the clamp beams on deck skins. It is fitted and equipped with a continuous closure device (primary / secondary seal) between the tank shell and the floating roof edge.The purpose of the internal floating roof seal system is to minimize vapor zone above the stored liquid. This system reduces emissions and evaporative losses of storage products, and less corrosive or oxidizing elements would be produced in the tank when removing the vapor zone from the fixed roof storage tanks.For floating roof seals have been widely used for storing the petroleum products, FLOAT-TEK provides the best quality of internal floating roof seal systems to every petrochemical industry. Based on our years of specialized experiences in designing, manufacturing and installing all types of tank seal accessories, FLOAT-TEK warrants every internal floating roof seal system comply with the environmental regulations and the latest edition of API 650 Appendix H standard.All parts are manufactured under FLOAT-TEK high quality control, and all floating tubes are leak-tested. In addition, all components can be easily accessed through an existing manhole without any special tools.
Deck skin on floating tube type --
From an idea of “Steady” tray combination by full contact on the storage products, FLOAT-TEK designs and produces an unique “Tray Combination” type of honeycomb floating deck to minimize the vapor space much smaller than the floating tube type’s one. The honeycomb floating decks are economic cost and provide the highest enclosure. No more vapor emission would occur under the full contact cover of honeycomb decks.

FLOAT-TEK’S Patent FL-HCT® is outstanding advanced liquid mounted version of Honeycomb Tray model type. This model combines all benefits of most floating roof deck types in the markets. It improves the weakness of open Sandwich Honeycomb Type deck design in order to have easy installation, saving huge cost for customers, no maintenance required, providing strong strengths, durability, corrosion resistance and high efficiency at reducing emission loss…. This is definitely the best deck design for all oil owners. To learn more about this product, please contact us for more details.
Design Advantages: Safety Full Liquid mounted design, sealing efficiency up to 99% Meet NFPA® 11, Rim fire protection Strong structure strength Easy, Quick, Economic and Safe Installation All installation parts can be easily put through tank manhole Combine Rim fire System, which can stop fire explosion in 30 seconds Economic material & delivery cost No maintenance required Lower cost for firefighting system
Material : Stainless Steel, or AluminumRim Space : 180mm +/- 100mm, 150mm +/- 100mm, 200mm +/- 100mm (Rim space will be different according to tank size.)
Double Wiper SealTwo wiper seals are vapor mounted and overlapped by each other. These seals completely cover the space between the tank shell and the edge of the internal floating roof. The wiper seals are continuous and made from high quality material of 100% aromatic resistance.Double wiper seals are easily to install and have a low cost.
Mechanical Shoe SealThe mechanical shoe seal is a metal sheet held vertically against the tank shell by spring. It is connected by brace arms to the floating roof. A flexible coated fabric (continuous seal) spans the annular space between the shoe plate and the rim plate of the floating roof.This seal offers actual advantages of universal resistance to all storage products, good emission reduction, long service life and liquid mounted.
Compression type mechanical sealCompression type mechanical seal is designed by metal sheets which are forwarded vertically against the wall of storage tank by tension force which is connected to the floating deck. This type of seal virtually offers advantages of universal resistance to all storage products, good emission reduced, long service life and liquid mounted.
Foam Seal & Wiper SealThe primary foam seal is liquid mounted type composed of foam blocks and envelopes; the secondary wiper seal is vapor mounted type. The envelope is designed to prevent liquid capillary action and provide a long service life for B.T.X and other strong chemical storage tanks.This foam seal can effectively reduce VOC emissions and project losses of liquid products completely.

Primary SealExternal Floating Roof Seal System
Foam Seal typeThe flexible foam filled with primary rim seal is mounted in the bottom position of the seal contacted with the stored products.FLOAT-TEK foam seal is comprised of a series of polyurethane foam blocks covered by an envelope and compressed between the tank shell and the floating roof rim. The foam blocks are held down by steel plates. This mounted-type seal eliminates vapor area.The curtain seal prevents any vapors passing between the roof and the metal frame or hanger bar.
Mechanical Seal Weigh load typeThis pantograph type mechanical shoe seal is the most widely used design on external floating roof tanks. The metallic band is formed as a series of shoes that are overlapped together to form a ring and held against the tank shell by pantograph type mechanical device. The assembling counterweight and arms exert a constant pressure to push the shoe against the tank shell.

Mechanical Seal spring type
Primary Seal
This spring type mechanical shoe seal has an economic and simple design. It is easy to install without hot work, such as welding, and gives good performance for sealing. The shoes are held in permanent contact with the tank shell and extended into the product by hanger arms. The material of pushing spring is high tensile stainless spring steel, and the spring pushes the shoe at two positions, upper and lower. The vapor membrane covers the vapor space between the shoe and the roof from the atmosphere.
Secondary Seal
Secondary Seal
The secondary seal reduces the evaporation losses of the primary seal, and it also prevents the rainwater and other products from falling into the stored products. The compressed plates may be mounted on horizontal or vertical type of roof rims and made to accept specific bolt pitching. The overlapping of compressed plates give strong sealing pressure to the tank shell.The wiper tip complies with a UV and weather resistant type of synthetic rubber and exerts a high sealing efficiency. The shunts complies with API 2003.
