Hydraulic Hose
Hydraulic hoses are typically made from a combination of synthetic rubber, thermoplastics, and metal reinforcements, each contributing to the hose’s overall performance. The inner tube, often made of synthetic rubber or thermoplastic, must be compatible with the hydraulic fluid and resistant to degradation. The reinforcement layer, usually composed of braided or spiral-wound steel wire or textile fibers, provides the strength to withstand high pressures. The outer cover, made from abrasion-resistant materials like rubber or thermoplastic, protects the hose from environmental damage, including UV rays, chemicals, and physical wear.
We can provide a wide range of types of hydraulic hoses, each coming in various sizes to meet different needs. Our various types of hose meet or exceed general standards such as SAE, DIN, ISO, etc. They, particularly hydraulic hoses, serve a wide array of uses and are especially suitable for the manufacture and maintenance of construction machinery such as excavators, agricultural machinery, coal mining machinery, etc. Hydraulic hose pipe is engineered to meet the needs of users seeking high-performance hoses.
How Do You Properly Install a Hydraulic Hose?
Proper installation of a hydraulic hose is critical to ensure safety and optimal performance, and different types of hydraulic hoses may have slightly different installation considerations depending on their design and material. First, when choosing a hydraulic hose, make sure to get the right length from a reliable hydraulic hose manufacturer, leaving some slack to accommodate movement and avoid excessive tension. Overstretching or leaving the hose too loose can lead to premature failure. Different types of hydraulic hoses might have specific requirements for routing, so always avoid sharp bends or twists by using proper routing techniques and, if necessary, installing bend restrictors to maintain the hose's integrity. Secure the hydraulic hose using clamps or brackets to prevent movement or vibration that can cause wear. Ensure the fittings are compatible and tightened to the manufacturer’s specifications, avoiding over-tightening, which can damage the connection or cause leaks. Double-check that the hose does not contact sharp edges or abrasive surfaces, as these can weaken the outer layer. In case of any damage or wear, timely hydraulic hose replacement is essential. After installation, test the system under controlled conditions to ensure there are no leaks or other issues. Following these steps will enhance the safety and longevity of the hydraulic system.
What is a hydraulic hose?
A hydraulic hose is a pipe used to transport hydraulic oil or other liquids in hydraulic systems. It can withstand high pressure and high temperature, and ensure the flow of liquid and pressure transmission. Hydraulic hoses are widely used in machinery, construction, mining, shipbuilding, and other fields, especially in environments that require high efficiency and high pressure.
As a supplier of hydraulic hoses, we can provide the most suitable hose for your hydraulic system. You only need to tell me the medium to be transported, the working environment and working pressure, etc., and we can discuss further.
Hydraulic hoses usually consist of the following three layers: inner tube, reinforcement layer, and out cover. The inner tube is in direct contact with the medium and is generally made of oil-resistant and corrosion-resistant synthetic rubber. The oil resistance prevents the hydraulic oil from reacting with the pipe wall or being corroded. Depending on the working pressure level of the pipeline, the number and density of the reinforcement layer will vary. Common structures include single-layer steel wire braiding, double-layer steel wire braiding, four-layer steel wire winding, one or more layers of fabric braiding, etc. Hydraulic pipes with steel wire reinforcement layers can withstand higher pressures. The reinforcement layer increases the strength of the hose and provides pressure resistance. The outer layer can protect the hydraulic pipe from external environmental factors such as wear, ultraviolet rays, chemical corrosion, temperature changes, etc., which can effectively protect the hydraulic pipe, extend its service life, and ensure that the hose can work normally in harsh environments.

How to avoid hydraulic hose failure?
Hydraulic hose failure can occur due to a variety of reasons. For instance, when using an industrial high pressure hose, exceeding its pressure limit, which is a common scenario with high-pressure applications, can lead to bursting. This not only causes the need for high pressure hose replacement but also incurs a significant hydraulic hose cost. Spiral hydraulic hoses, known for their robust construction, can still fail if subject to improper installation, like sharp bends, or wear and tear over time from contact with rough surfaces. Abrasion from such sources is a frequent issue, especially if the hose lacks proper protection.
Contamination within the hydraulic fluid can damage the inner lining of any type of hose, be it a standard or custom made hydraulic hose. Custom made hydraulic hoses are designed to fit specific operating conditions precisely, but they are not immune to problems. When damage occurs, hose repair might be an option, depending on the extent of the issue. However, if the damage is severe, replacement becomes necessary, again adding to the overall hydraulic hose cost.
To prevent failure, always select a hose that perfectly matches the operating conditions of the system, including pressure, temperature, and fluid type. Regular inspections are essential to catch early signs of wear, such as cracks, bulges, or leaks. Proper installation techniques, including avoiding sharp bends or twists, will reduce mechanical stress. Additionally, using protective sleeves or routing hoses away from abrasive surfaces can minimize external damage. By performing preventative maintenance and strictly adhering to hydraulic hose manufacturer recommendations, you can greatly extend the hose’s lifespan and reduce the likelihood of costly breakdowns that often accompany hydraulic hose failures.
What Are Hydraulic Hose Fittings, And How Do You Choose The Right Ones?
Hydraulic hose fittings play a crucial role in connecting hoses to other components in a hydraulic system, such as pumps, valves, or cylinders. Different types of hydraulic hoses have their own requirements when it comes to choosing the appropriate fittings.
These fittings come in various types, including threaded, crimped, and quick-connect styles, each suited for specific applications. The choice of fitting depends on factors such as the system’s operating pressure, the type of fluid, and the compatibility with the hose material. For instance, industrial high pressure hoses, which are designed to withstand significant pressure, often pair well with crimped fittings that offer strong, reliable connections for high-pressure systems. Spiral hydraulic hoses, known for their durability and flexibility in certain applications, also need fittings that can complement their structural characteristics.
Threaded fittings are common and provide a secure connection, but they require careful tightening to prevent leaks. Crimped fittings, often permanently attached, offer strong, reliable connections for high-pressure systems. Quick-connect fittings are ideal for applications requiring frequent assembly or disassembly, such as in mobile equipment. When selecting a fitting, consider the size and thread type to ensure a proper match with the hydraulic hose and system components. Custom made hydraulic hoses might have unique dimensions or material properties, making it even more essential to choose fittings that are specifically compatible.
Always follow the manufacturer’s specifications and guidelines to avoid compatibility issues that could compromise system integrity or lead to leaks.
