Draining rain water from an external floating roof is important to make sure the external floating roof will not built up too much water on top, which could even cause sinking of the roof. Universeflex has developed an excellent solution by introducing Tank Drain hoses for this application. The major advantage of a hose is that it does have a minimum number of connections, therefore eliminating much of the potential problems with other draining systems.
As the Universeflex Drain hose is a complete system, including the connections, the lead ballast cable and the suspension system, it is easily installed by a contractor crew. Each hose is individually tested prior the shipment, to ensure its performance. As a result of the flexible nature of the drain hose, it will even be able to deal with frozen rain water inside.
Universeflex Drain Hose system is designed for immersion inside storage tanks to drain rain water from a floating roof, to ensure the proper drainage of water from the aboveground storage tank’s floating roof. Specially compounded covers are used to resist immersion in high aromatic or corrosive liquids.
Lining: Polypropylene or PTFE lined hose, depending on the type of hose specified or required.
Reinforcement: Textile reinforcement with a double high tensile wire helix to resist collapsing by external pressure when immersed.
Pressure: Although these hoses are rainwater drains experiencing low pressures when in use, the integrity of the hose assemblies is checked, after ballasting, by testing to 14 bar with water and vacuum testing to – 1 bar.
Full and detailed test and material certificates are supplied as a standard.
Cover: Wrapped fabric finish in following options:
– Antistatic Polypropylene fabrics, to resist at 100% aromatic content.
– Nanotec Pure Teflon Cross laminate film (MATEC® Patent N° IT0281052) resistant to all solvents, Chemicals and aromatics at any concentration.
Lead ballast: On Request, each hose assembly incorporates (inside) a permanently attached stainless steel cable and lead discs to prevent the hose from floating in the stored product.
Repeatable lay pattern: Universeflex Drain hoses are installed to form a single coil repeating lay pattern with a 360° coil.
Antistaticity: All hoses are supplied electrically continuous.
Installation: 2 Polyurethane Scuffring Support saddles and chains for roof attachment, are supplied and the roof end of each hose is marked as follows: “ATTACH THIS END TO ROOF”.
Flanges: Generally mild steel nipples with fixed ASA150 R/F flanges are supplied. Other flanged drillings and material types are available including swivel flanges and bronze flanges. The ballast connection is a stainless steel wire rope section permanently welded to the hose nipple.
Universeflex Drain hoses are designed , tested and manufactured to customer specifications to offer the following features:
The Universeflex Hinge Drain System was designed to innovatively provide a better solution to floating roof drainage problems. It combines both the flexibility of composite and hose systems with the strength found in rigid pipe/swivel join systems. The Hinge Drain System is basically a steel pipe drain system with an Angular flexible joints that withstand an extremely wide range of service conditions.
Universeflex Hinge Drain System offers Long Maintenance-Free Service and effectively provides positive roof drainage with maintenance-free and worry-free operation. This results in extended service life, with no hose kinking or clogging, and there is no stress loading on O-rings, bearings or seals. Instead of costly swivels, the Hinge Drain System employs unique flexible joints in a straight-line design, with no offsets to cause unbalanced loading.
The Universeflex Hinge Drain System is easily installed in a fixed position, requiring a minimal operating area. With a designed continuous slope, the Hinge does not allow sediment to become trapped in the system. It is designed for submerged service with no lubrication required, and there are no corrosion freeze-ups. All components are compatible with 100% aromatic products and can withstand high design pressures.
Advantages of Universeflex Hinge Drain System compared to traditional Swivel Joint Systems:
Advantages of Universeflex Hinge Drain System Compared to Hose Drain Systems:
Other Advantages of Universeflex Hinge Drain System:
Universeflex Hinge Drain flexible joint is designed with inner and outer stainless steel wire helixes to maintain hose rigidity when subjected to internal or external pressures. Multiple inner layers of polar and non-polar thermoplastic materials, prevent product permeation through the hose, even from such products as MTBE. The outer layers in Antistatic woven fabric, protect the inner hose materials. Its high design pressure also makes the Universeflex Hinge Drain System suitable for use with fire fighting foam delivery systems.
The Drain flexible joint hinge-pin design uses stainless steel & Teflon bushings and spacers to eliminate binding and assure flexibility. No lubrication is required. The reinforced side plates transfer the load around the flexible hose, eliminating stress on the hose end connections and minimizing the possibility of hose end failure.
These side plates are available carbon steel (galvanized or prime coated) and stainless steel materials.
Diameters from 2” to 12” are available.
