SAE 100R13 DN25/1 inch 350Bar mining hydraulic hose
1. Solutions for harsh working conditions
Applicable equipment and scenarios:
Mining machinery: rock drilling trolleys, hydraulic supports, fully mechanized mining equipment, underground conveyors, mining excavator power systems;
High-risk environments: underground coal mines (including gas environments), metal mine tunnels, tunnel projects and other flammable and explosive, high-dust, humid and corrosive areas;
Core functions: transmission of high-pressure media such as hydraulic oil and emulsion, driving key equipment actions (such as support, propulsion, and cutting).
Two or three layers of reinforced structure, defining high performance standards
Structural layer Material/process Core function
Inner rubber layer NBR nitrile rubber + tear-resistant additives Resistant to mineral oil/emulsion corrosion, anti-media penetration
Reinforcement layer 4 layers of high-tension steel wire winding Withstand 350Bar high pressure, anti-pulse fatigue (≥500,000 times)
Outer rubber layer SBR synthetic rubber + flame retardant coating Anti-wear, anti-ultraviolet, flame retardant (in accordance with ISO3795)
Performance highlights:
Ultra-high pressure bearing: 350Bar working pressure (burst pressure ≥1400Bar), meeting the needs of heavy equipment in mines;
Extreme temperature adaptation: Maintain flexibility under working conditions of -40℃ to +100℃, worry-free in low temperature/high temperature environment underground;
Dynamic flex life improvement: The steel wire winding structure has 300% higher bending resistance than the braided hose, adapting to frequent equipment movement.
3. Why do mining customers only choose SAE 100R13
Dual optimization of life and cost
Abrasion-resistant design: Carbon black is added to the outer layer to resist ore friction, and the service life is twice as long as that of ordinary hoses;
Anti-corrosion connector: Galvanized carbon steel connector is standard (optional 24°/74° cone seal) to prevent leakage caused by moisture corrosion underground.
