Why Choose Hongruntong Marine Hydraulic Oil Hoses?
► Structural Design
Four-layer high-tensile steel wire spiral reinforcement (4SP) with an oil-resistant synthetic rubber inner tube, intermediate wire reinforcement layers, and an abrasion/oxidation-resistant synthetic rubber cover. The spiral winding ensures extreme pressure resistance while maintaining flexibility.
► Performance
Operating pressure up to 51 MPa (dynamic) / 85 MPa (static), burst pressure 4× working pressure. Temperature range: -40°C to +100°C, with a pulse endurance exceeding 500,000 cycles (ISO 6803).
► Fluid Compatibility
Compatible with mineral-based hydraulic oils, biodegradable fluids, and water-glycol mixtures. Excellent fuel resistance (ISO 6072 compliant).
► Environmental Suitability
UV- and ozone-resistant outer layer, ideal for construction, mining, and heavy machinery in harsh conditions. Complies with EN 853, SAE 100R12.
Application
► Excavator Hydraulic Systems - Powering boom, bucket, and swing motor operations
► Loader Hydraulic Circuits - Controlling lift and tilt cylinders in material handling
► Bulldozer Hydraulic Drives - Heavy-duty transmission for blade and steering systems
► Concrete Pump Trucks - High-pressure delivery for boom movement and concrete pumping
Why Hongruntong Marine Stands Out
► Ultra high pressure (69 MPa) – Rated for 10,000m depth operations.
► Corrosion-proof construction – Ideal for subsea umbilicals and BOP controls.
► Long-term reliability – Tested under API 17K and NORSOK standards.
► Low maintenance – Reduces downtime in critical offshore applications.
FAQ
1. What is a hydraulic oil hose?
A hydraulic oil hose is a reinforced rubber hose designed to convey hydraulic fluid under high pressure in machinery and industrial systems.
2. What types of reinforcement are used in hydraulic hoses?
They typically use braided or spiral-wound high-tensile steel wire reinforcement for pressure resistance.
3. What pressure ratings are available?
Hydraulic hoses are available with working pressures from 70 bar (1,000 PSI) up to 420 bar (6,000 PSI) or higher.
4. What temperature range can hydraulic hoses withstand?
Most operate from -40°C to +120°C. High-temp hoses can reach +150°C, depending on material.
