The high-pressure steel wire hydraulic hose structure is mainly composed of an inner rubber layer, a middle rubber layer, four or more layers of alternately wound steel wire reinforcement layers and an outer rubber layer.
The inner rubber layer has the function of making the conveying medium bear the pressure and protecting the steel wire from erosion, the outer rubber layer protects the steel wire from damage, and the steel wire (ф0.3-2.0 reinforcing layer) is a skeleton material for reinforcement.
High pressure steel wire hydraulic hose (high pressure oil hose) Use: High pressure steel wire reinforced hydraulic hose is mainly used in mine hydraulic support, oil field development, suitable for engineering construction, lifting transportation, metallurgical forging, mining equipment, ships, injection molding machinery, agricultural machinery , Various machine tools and mechanized and automated hydraulic systems in various industrial sectors to transport petroleum-based (e.g. mineral oil, soluble oil, hydraulic oil, fuel oil, lubricating oil) and water-based liquids (e.g. Emulsions, oil-water emulsions, water) and liquid transmission, the highest working pressure can reach 70-120Mpa.
High-pressure steel wire hydraulic hose (high-pressure oil hose) Working temperature: -40 ℃ ～ 120 ℃
