GH HILCOFLEX PU KULI

HPK

Durable, electro-conductive multi-purpose polyurethane hose

Applications

  • Refineries
  • Industry
  • Waste disposal
  • Military
  • Industrial and mine fire services
  • Transporting oil, fuel and other flammable liquids
  • Ship fuelling
  • Tank cleaning
  • Firefighting in mines and other potentially explosive areas
  • Powder extinguisher hose

Features

  • Outstanding abrasion resistance
  • Extremely tough, resistant to wear and durable
  • Resistant to oil, petrol and chemicals (see resistance table)
  • Resistant to ageing and ozone
  • Lightweight and flexible compared to mandrel-wound industrial hoses
  • Very good flexibility at low temperatures

Construction

Jacket lining:

  • High-tenacity polyester yarn, circular woven
  • Totally embedded in the rubber, offering optimum protection against damage
  • Interwoven copper strands for electro-conductivity
Lining and jacket:
  • Thermoplastic polyether polyurethane, extruded through the weave in a special one-step production process
  • Electrical resistance less than 10^6 ohms
  • Highly resistant to abrasion, 4–5 times longer service life than nitrile hoses
  • Inside: very smooth for minimum pressure loss
  • Outside: very smooth for good flexibility

Pressures

Working pressure:
Specifications apply only to the hose (medium water, 20°C). The potential working pressure may be lower than specified above for hose lines with couplings due to the nominal pressure of the couplings or the type of assembly. For compressed air, the maximum working pressure is 25% of the burst pressure.

Maximum working pressure:
Approval can only be given by the manufacturer upon clarification of the exact area of application.

Breaking strength

The maximum tensile load in continuous use should not exceed 1/3 of the breaking strength.

Standard length

100 m

Standard color

Army green

Temperature

–50°C to +75°C (depending on medium)

Individual solutions

Single lengths up to 200 m
