Internal Floating Roofs
"HC" Full-Contact Type
The ALLENTECH HC Full Contact Internal Floating Roof is the most advanced and efficient aluminum IFR available to the petrochemical industry today. Constructed of a series of seal-welded interlocking aluminum honeycomb modules, the ALLENTECH HC IFR is rugged and durable. The average size ALLENTECH HC IFR provides more than 350% excess buoyancy — far exceeding typical buoyancy of other designs and with its ultra low profile, the ALLENTECH HC IFR maximizes tank capacity and minimizes filling losses.
Our patented Hook and Pin joint detail creates a true "full contact" assembly without gaps between modules minimizing evaporation losses through joints while maximizing strength, stiffness and durability.
Also adding to its strength, the HC Full Contact IFR features fully welded construction. Each module is seal welded, pressure tested and certified leak free at our integrated design and manufacturing facility prior to shipment. Since components are pre-fabricated, there is no field cutting or gluing, adding to the product's stability and customer assurance and satisfaction.
For added quality, each aluminum module skin is two and a half times the minimum API thickness. Modules are fitted with a re-sealable port to allow field-testing in accordance with API recommendations. Bolts are stainless steel with stainless or aluminum nuts for strength and corrosion resistance. Joint fasteners stay out of the liquid for the same purpose.
ALLENTECH uses custom extrusions and designs each IFR to each customer's application. ALLENTECH's HC IFR meets or exceeds all EPA, API, ASME and Aluminum Association codes.
The HC IFR is price competitive when compared with steel designs and does not require a hydrotest per API recommendations. And, because it is pre-fabricated, quality control is maximized and installation is completed in less than one third the time.
