DECKMASTER GRP FLOATING ROOF

The Deckmaster GRP Advanced Composite Floating Roof is a seamless, nonmetallic full-contact floating roof. Its gastight polypropylene honeycomb core is “sandwiched” between multiple layers of fiberglass utilizing modern high-grade vinyl ester resins designed to be resistant to most hydrocarbons. The result is a smooth, seamless, and virtually indestructible full-contact floating roof that is also corrosion free, thus necessitating little or no maintenance. The Deckmaster remains in full contact with the stored product, preventing evaporative losses. The low-profile cross section of the roof maximizes the storage capacity of the tank. Designed to accommodate both a mechanical shoe primary seal and a secondary seal, the Deckmaster is fully gastight, leak proof, and virtually unsinkable. The robust design also enables it to withstand operational stresses such as pigging and butter washing. From diameters as large as a football stadium to large-scale external floating roof applications, this technology represents the absolute premium in floating roof performance with best-in-class emissions, corrosion resistance, ability to handle dynamic loads, buoyancy ratio, walkability, and longevity.

ALUMINUM GEODESIC DOME ROOF

The HMT Aluminum Dome features a clear-span, all-aluminum, lightweight, corrosion-resistant structure which sets a new standard for performance in aluminum domes. HMT’s unique clamped-panel design and attention to detail at critical locations result in a cost-effective solution that provides superior protection of your stored product.

ALLENTECH HC FULL CONTACT FLOATING ROOF

The Allentech HC Full Contact IFR is a premium Honeycomb Full Contact Aluminum IFR. The Allentech HC is designed in accordance to API650 and EN14015 with a minimum buoyancy ratio of 2x against the roof dead load plus friction force exerted by perimeter seals using a drag coefficient of no less than 3 lbs/ft. The roof is capable of staying afloat while having two adjacent flotation compartments flooded. The roof buoyancy is based on a Specific Gravity of 0.7 or the stored product, whichever is less. The panel modules are 5ft x 10ft x 1.5in deep (1524mm x 3048mm x 38.1mm). Rim modules are designed to match the tank shell radius. Each sandwich-module consists of a top and bottom layer of .050in aluminum sheet with an internal honeycomb structure to provide stiffness. A high quality aluminum extrusion forms a frame around the sheet and honeycomb, and this is completely seal welded into a fully enclosed buoyant compartment. Each module contains a resealable vapor detection port for pressure testing in our factory, and also for future testing during out-of-service maintenance. Damaged panels that are installed can be easily replaced during future maintenance. Every module is fully inspected and pressure tested with helium leak detection equipment prior to shipment. The Hook and Pin design of the modules allows for quick installation and forms an high strength bolted seam with extremely low seam emission losses.

SEALMASTER® PRIMARY & SECONDARY

The Sealmaster floating roof seal system was developed over 35 years ago, with the goal of making a seal that adjusts to the irregularities of tanks while remaining gas-tight and virtually maintenance-free. The solution is the Sealmaster seal system. The Sealmaster is comprised of fully hardened compression plates, extending from the floating roof rim to the tank shell and down into the stored product, thereby providing a non-combustible protective sheath over a fully-heat-welded vapor barrier encapsulating the entire vapor space.

GUIDE POLE SLEEVE SEAL

The Enviro-Sleeve Gauge Pole Seal was designed as a zero-emissions, reliable, durable, and maintenance-free guide pole sleeve that has the capability to be retrofitted without any modifications to the EFR. For a vapor-tight guide pole sleeve that can be installed easily, quickly, and as a custom-fit solution with no maintenance, while lasting the life of your tank, choose the Enviro-Sleeve.

PIVOT MASTER® Floating Roof Drain System

SUMPMASTER SUMP VALVES

The SumpMaster is a sturdy sump valve designed to prevent product flow onto external floating roofs from drain system failures. The SumpMaster addresses several problems with traditional check valves, including more effective sealing at the potentially lower pressures encountered during a drain system failure, and not restricting drain flow rates calculated during the design of the floating roof.

FLEX-A-SEAL

Rim-mounted Compression Plate Type Wiper Seal The HMT Flex-A-Seal Secondary Seal is one of the most economical and effective types of secondary seals available. Easily installed and maintained, the HMT Flex-A-Seal’s ability to meet or exceed stringent gap specifications for secondary seals has earned its approval from governmental regulatory agencies throughout the U.S. and European markets.

SEAL KING SECONDARY SEAL

Low-Profile Secondary Seal The Seal King low-profile secondary seal was specifically designed to give storage tank owners the ability to maximize tank working capacity. With its extremely low profile, the Seal King increases the working capacity of a floating roof tank, allowing tank owners to increase competitiveness and profitability. The Seal King also has unsurpassed vapor-sealing ability and exceptional water-shedding capability.
