馬牌鋼絲纏繞膠管結構和規格（英文版）說明
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.
