Applications
Universeflex BLH Bottom Loading hose is a strong, robust and low elongation hose, suitable for the most demanding applications such as Loading arms, Hose towers, for transfer of :
- A wide variety of acids and solvents, (BLH CHEM).
- Aggressive chemicals (BLH PTFE).
- Hydrocarbon products including fuel oils, diesel, leaded and unleaded gasline, lubricating oils, kerosene, MTBE and 100% aromatics (BLH OIL).
The major advantage of a Bottom Loading hose, versus a traditional Loading Arm, is that it does have a minimum number of connections, therefore eliminating much of the potential leak problems, minimizing the general costs.
Construction
A specially FIRETEC designed hose for bottom loading applications having flameresistant fabric under outer cover. Extra strong / low elongation ARAMEX reinforcement, polypropylene films and fabrics, high density polyethylene films reinforcement, and Polyester film barrier layers. PVC coated polyester fabric cover, fire resistant CL1, abrasion, weather and ozone resistant.
On request, special Elastar outer PU based cover is available for superior abrasion and weather resistance, or in the Marine enviromentals. Universeflex BLH PTFE, is constructed around a pure PTFE inner liner or Nanotec (PATENT n. IT 0281052) liner on request, for superior resistance to aggressive chemicals.
Specifications
Temperature range from -40°C to + 100°C
W.P. 15 Bar – Safety factor 5:1
Universeflex BLH hose assemblies are tested at 1-1/2 times rated working pressures for safety and reliability, in accordance with EN ISO 1402.
The securing ferrule, at one end of the hose, is permanently marked by embossing, with manufacturer’s name, nominal bore, serial number and the test date. Full test certification, including Electrical continuity test, can be supplied on request.
Burst pressure indicated, is at ambient temperature when tested in accordance with EN ISO 1402 (BS 5173 section 102.10:1990).
Electrical continuity is achieved by the two wires bonded to the end fittings, this helps dissipate accumulated charge and to avoid static flash. The electric resistance of hose assemblies is less than 1 ohm/mt, as required by EN ISO 8031:2009, 4.7. Upon request it’s possible to manufacture Universeflex BLH hoses in accordance to the Directive 94/9/EC “Atex”, with a special outer antistatic black cover and cable for ground connection.
Assemblies are suitable for use with a vacuum not exceeding 0.9 Bar. According to the Standard BS 3492:1987 description, Universeflex BLH hose meets the requirements for type AX & BX, for all products included in “Class 1”. Universeflex BLH hoses are always supplied in the Firetec version to meet the Fire retardand performance criteria acc. to European Standards EN 13765:2010 Normative, Annex G, and with ADR self-estinguish CL1 characteristics.
Firetec hose utilize a series of fire retardant barriers and an outer cover made of special ADR self extinguish CL 1 coated fabric.
All Universeflex hoses meets the EN, CE, AS, U.S. Coast Guard requirements, NAHAD Guidelines, are Lloyd’s and DNV approved.
