Hydraulic Line Pipe Smooth Flow Corrosion Resistant Easy To Connect

Description

The Hongruntong Marine hydraulic oil hose is engineered for high-pressure hydraulic systems that demand reliability, flexibility, and long-term chemical resistance. The hose features an oil-resistant inner tube made from nitrile or equivalent synthetic rubber, providing excellent stability and resistance against mineral oils, synthetic hydraulic fluids, and fire-resistant formulations. Its multi-layer high-tensile steel wire reinforcement ensures superior burst strength, fatigue resistance, and impulse endurance, even under cyclic or pulsating pressures. The abrasion-resistant outer cover protects against mechanical wear, UV exposure, ozone, and environmental degradation, ensuring durability in harsh marine, industrial, and mobile applications. Optimized flexibility allows routing through confined or complex machinery layouts without kinking or stress on fittings. Each hose undergoes rigorous hydrostatic, impulse, and flex-fatigue testing, ensuring reliable performance, leak-free operation, and extended service life. Hongruntong’s strict quality control standards guarantee consistent manufacturing precision and traceability.

Case Study

A wind turbine manufacturer faced frequent hydraulic hose failures in their pitch control system due to high-frequency flexing, vibration, and exposure to harsh outdoor conditions. Conventional hoses failed prematurely, causing costly maintenance and system downtime. Hongruntong Marine supplied hoses with reinforced spiral steel layers, chemical-resistant inner tubes, and durable outer covers designed for outdoor exposure. During a 36-month field study, the hoses demonstrated zero leaks or bursts, maintaining system performance even under continuous operational cycles and extreme temperatures. Maintenance teams noted significantly reduced downtime and fewer emergency replacements. The hoses’ flexibility allowed for smooth installation in confined routing spaces within the turbine nacelle, avoiding stress on fittings and reinforcement layers. This case highlights Hongruntong’s ability to provide highly reliable, long-lasting hydraulic hoses for applications where continuous flexing, environmental exposure, and high-pressure performance are critical.

Specifications

Feature

High Pressure Performance
The reinforcement design enables the hose to withstand extreme working pressures without deformation or failure. Multi-layer spiral or braided steel wire reinforcement ensures burst strength exceeds operational requirements by a safety factor, providing reliability even under fluctuating pressures. Rigorous hydrostatic testing validates that each hose can endure pressure spikes and long-term use.

Advanced Chemical and Temperature Resistance
The inner tube is resistant to a wide variety of hydraulic fluids, including mineral oils, synthetic esters, phosphate esters, and water-glycol fluids. It maintains dimensional stability under high-temperature operation, preventing swelling, cracking, or premature aging. Laboratory testing confirms long-term compatibility, making the hoses suitable for marine, industrial, and mobile hydraulic systems with diverse fluid requirements.

Abrasion Resistant Outer Cover
The outer layer protects the reinforcement from external wear, UV light, ozone, and chemical exposure. It is formulated for high toughness to resist cuts, impacts, and friction in harsh environments. The cover ensures the structural integrity of the hose over prolonged service periods, reducing maintenance frequency and extending service life.

Enhanced Flexibility for Tight Installation
Despite its robust construction, the hose maintains excellent flexibility. The combination of inner tube material, reinforcement geometry, and cover formulation allows routing through confined spaces and complex machinery layouts without kinking or overstressing the hose. Repeated bending and flexing tests confirm long-term durability, enabling safe operation in dynamic and mobile systems.

Applications
