Hydraulic systems play a vital role in modern industry and machinery, providing efficient and reliable power transmission and control solutions for a variety of applications. As one of the key components of the hydraulic system, hydraulic hoses play a vital role in ensuring the smooth operation of the system and transmitting hydraulic energy. This article will delve into the knowledge of hydraulic hoses to help you better understand and apply hydraulic hose technology.
1. What is a hydraulic hose?
A hydraulic hose is a flexible conduit used to transmit hydraulic energy. It is widely used in hydraulic systems to transfer a liquid medium (usually hydraulic oil) from one place to another. Hydraulic hoses usually consist of a multi-layer structure, including an inner tube, a reinforcement layer and an outer tube.
The inner tube is the inner layer of the hydraulic hose, which is in direct contact with the liquid medium. It is usually made of corrosion-resistant and wear-resistant materials, such as synthetic rubber or special plastics. The main function of the inner tube is to prevent liquid leakage and provide a channel for fluid transmission.
The reinforcement layer is the middle layer of the hydraulic hose, which is used to enhance the strength and pressure resistance of the hose. Common reinforcement materials include high-strength fiber materials such as steel wire braids or helical windings, and synthetic fiber reinforcements.
The outer tube is the outer protective layer of the hydraulic hose to prevent mechanical damage, resist corrosion and provide environmental protection. It is usually made of a material, such as rubber or plastic, that is resistant to abrasion and environmental elements such as UV rays, oils, and chemicals.
The design and selection of hydraulic hose depends on the specific requirements of the application, including operating pressure, flow rate, temperature range, media type and environmental conditions, etc. Proper selection, installation and maintenance of hydraulic hoses are critical to the safety and performance of hydraulic systems.
2. Structure and composition of hydraulic hose
The structure and composition of hydraulic hoses generally include three main parts: inner tube, reinforcement layer and outer tube. Each section has a specific function and material selection to ensure the hydraulic hose has the required performance and durability.
Inner Tube: The inner tube is the inner layer of the hydraulic hose and is in direct contact with the liquid medium. It is primarily responsible for the following functions: preventing fluid seepage and leakage, providing channels for fluid transfer, and resisting corrosion and wear. The inner tube usually consists of synthetic rubber and special plastics.
Reinforcement Layer: The reinforcement layer is the middle layer of the hydraulic hose, which is used to enhance the strength and pressure resistance of the hose. It is mainly responsible for the following functions: to withstand the internal hydraulic pressure of the system, and to prevent the hose from expanding or bursting. Common reinforcement materials include steel wire braids and steel wire helical windings.
Outer tube (Cover): The outer tube is the outer protective layer of the hydraulic hose to prevent mechanical damage, resist corrosion and provide environmental protection. It is mainly responsible for the following functions: protecting the hose from erosion and physical damage from the external environment, providing abrasion and chemical resistance, and the outer tube is usually composed of synthetic rubber and polyurethane.
With such a structure and composition, hydraulic hoses are able to withstand high pressures and dynamic loads while maintaining the safe transmission of fluids and reliable operation of the system.

Hydraulic hoses are used in the oil and gas industry to transfer hydraulic power and control operations. They are used in oil well drilling, oil and gas extraction, oil pipelines and pressure control systems, etc.
4. Standards and precautions for selecting hydraulic hoses
When selecting hydraulic hoses, there are several criteria and considerations to consider to ensure the proper hydraulic hose for a particular application:
Working pressure: Know the maximum working pressure required by the system and choose a hydraulic hose that can withstand that pressure. Make sure that the rated working pressure of the hose (more than 3 times the working pressure) can meet the system requirements.
Flow requirements: Select the appropriate inner diameter size according to the flow requirements of the system. Larger IDs provide greater flow, but also increase hose cost and weight.
Temperature Range: Consider the temperature range of the system's operating environment and select hydraulic hoses that will work within that range. Different materials have different temperature tolerances.
Medium type: Determine the type of medium used in the hydraulic system (such as hydraulic oil, water, etc.), and select a hydraulic hose compatible with the medium. Certain media may be corrosive to certain materials or cause hose degradation.
Environmental Conditions: Consider the environmental factors the hose will face, such as UV exposure, chemical exposure, etc. Choose an outer tube material with properties such as UV resistance and chemical resistance.
Bending Radius: Select hydraulic hoses according to the bending requirements of the system. Smaller bend radii allow for a tighter fit, but may also result in shorter hose life.
Standards and certifications: Make sure to choose hydraulic hoses that meet relevant standards and certification requirements, such as ISO, SAE, etc. These standards and certifications ensure that the quality and performance of hoses comply with international regulations.
Safety factors: Consider the safety factors of the hose, such as fire resistance and anti-static properties. In certain applications, these features may be critical to safety.
Manufacturer reputation: Choose a hydraulic hose manufacturer or supplier with good reputation and experience. They are able to provide high quality products and reliable technical support.
5. How to choose the right hydraulic hose manufacturer
Selecting the right hydraulic hose manufacturer is key to ensuring high-quality products and reliable technical support. Here are a few key points for choosing the right hydraulic hose manufacturer:
