Applications

• Suitable for use and recommended for fire fighting activities in:
• Municipal fire departments
• Industrial fire brigades
• Petrochemical fire protection
• Shipboard fire fighting
• Municipal supply lines
• Well Protection
• Heavy duty wash down
• Jetting
• Snow making
• Dewatering & slurrry applications
• Hydrant bypass

Suitable for many other applications requiring a heavy duty, high pressure hose resistant to petroleum, chemicals, ozone attack in extreme conditions;

Non fire fighting applications "OROFLEX" hoses with similar characteristics are also recommended

Hose Construction
Hose shall be made from 100% high tenacity synthetic yarn circular woven and completely protected and locked-in by tough highly resistant synthetic nitrile rubber, forming a single homogenous construction without the use of glues or adhesives of any type. Cover incorporates a QR square rib configuration under 4’ and SR single rib on 4” and over to enhance abrasion resistance.

Lining Properties

• Ultimate Tensile Strength: Tensile strength of the lining and cover shall not be less than 1500 psi (10,500 kpa ).
• Ultimate Elongation: 400 % minimum.
• Accelerated Aging Test: The tensile strength and ultimate elongation of the vulcanized rubber compound which has been
  subjected to the action of oxygen at a pressure of 300 psi +/- 10 psi (2100kpa +/- 70kpa) and temperature of 70 degrees centigrade +/-1 degree centigrade (158 F +/- 18 F ) for a period of 96 hours shall be greater than 60% of the original properties stated.

Abrasion Resistance:
Hose shall withstand more than 30,000 cycles on the taber abrasion machine (H22 wheel ;1 kiloweight). Other standard abrasion test data can be supplied on request, including UL, DIN, ETC..

Cold Resistance:
Hose shall have a capability of use down to - 36 F. Hose shall have no apparent damage to cover, reinforcement or lining when subject to the following cold bending test: A soft length of dry hose is to be firmly coiled and placed in a cold box at - 36 F for a duration of 24 hours. Immediately after removal of the hose from the box, hose should be uncoiled and laid out by one operator. Following this procedure, the hose shall not leak nor show any damage to the reinforcement when subjected to hydrostatic acceptance tests stated above.

Ozone Resistance:
Hose shall show no visible signs of cracking of the lining or cover when tested in accordance with ASTM D1149-64 (R1970), ASTM D518 Procedure B, 100pphm/118 F/70 hours.

Chemical Resistance:
Exposure to seawater and contamination by most chemical substances, hydrocarbons, oils, alkalis, acids and greases must have no effect on the short or long term performance of the
hose. A chemical resistance chart is available and Ati will supply specific chemical resistance data on request to the purchaser for unique applications.

Heat Resistance:
The hose when subjected to a static pressure of 100 psi ( 700 kpa ) shall be capable of withstanding a surface temperature of 1200 F for a minimum of two minutes without rupture or damage to the synthetic reinforcement.
