Product Structure

Product Structure: consists of an inner tube, middle rubber 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 (ф0.3-2.0 reinforcement) is the structure materials that providing 

reinforcement. 

Application

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, including petroleum base fluids 

which under specific pressure and temperature (e.g. mineral oil, soluble oil, mineral oils, fuels, lubrication), water 

based fluids (e.g. emulsion, oil-water emulsion, water), air and fluids, in industry department mechanization and 

automatic hydraulic systems. Its highest operating pressure could attain 70-120 Mpa.
