Product Structure
Consists of an inner tube, middle layer, two, four or six spiral wire reinforcements and cover. Inner tube is to transmit liquid under pressure and protect steel wire against corrosion while cover is to protect wire against damage. Wire layer (Ø0.3-2.0 reinforcement) is the structure materials that providing reinforcement.
 
Application:
High pressure wire reinforcement hydraulic hose mainly used in mine hydraulic support, oil exploration, suitable to engineer construction, crane transport, forging metallurgy, mining equipment, ships, injection molding machinery, agricultural machinery various machine tools, and carry hydraulic fluids for industry department mechanization and automatic hydraulic systems, including petroleum base fluids which under specific pressure and temperature(e.g. mineral oil, soluble oil, fuels, lubrication,) water based fluids(e.g. emulsion, oil-water emulsion, water), air and fluids, in industry department mechanization and automatic hydraulic systems. It's highest operating pressure could attain 70-120 Mpa. Note: Spiral hose specification refer to GB/T10544-03 standard, DIN 2003, EN 856, SAE J517
 
Working Pressure:
Oil: -40°C to +100°C, Air: -30°C to 50°C, Water Emulsion under +80°C
