How Do You Protect Hydraulic Hose?

The hydraulic hose is important in resource conveyance in the industrial field, including the building and mining industries. Hydraulic hose maintenance is also very important to ensure that heavy-duty machinery can work as normal. 

Here are some tips that help you protect your hydraulic hose properly, to make it work longer to expand its service life.

Let’s dive into this guide to get some hacks. 

What Causes Hydraulic Hose Damage

Hydraulic hose damage can stem from a variety of factors, both internal and external.

Here are some of the most common causes resulting in the hydraulic hose damages:

• Abrasion: This is the most frequent culprit. Constant rubbing against machinery, sharp edges, or rough surfaces wears down the hose’s outer cover, exposing the inner layers and ultimately leading to failure.
• Kinking and Bending: Excessive bending or twisting can weaken the hose’s internal structure, causing cracks and leaks.
• High Temperatures: Exposure to extreme heat can cause the hose’s materials to degrade, harden, and become brittle. This makes them more susceptible to cracking and rupture.
• Low Temperatures: In very cold conditions, hoses can become stiff and brittle, increasing the risk of cracking or splitting, especially during flexing.
• Chemical Exposure: Certain chemicals can attack and degrade the hose’s materials, weakening them over time.
• Internal Pressure Surges: Sudden pressure spikes within the hydraulic system can cause excessive stress on the hose, leading to leaks or ruptures.
• Improper Installation: Incorrectly installed fittings, crimped hoses, or insufficient clamping can all weaken the hose and increase the risk of failure.
• Age and Fatigue: Over time, hoses naturally degrade due to age and the cumulative effects of use and environmental factors.

Preventing these issues involves:

• Proper routing and installation: Avoiding sharp bends, securing hoses properly, and maintaining adequate clearance.
• Using appropriate hydraulic hose guards: Such as spring guards, spiral wraps, or sleeves to protect against abrasion and external damage.
• Regular inspection and maintenance: Regularly checking hoses for signs of wear and tear and replacing damaged hoses promptly.
• Selecting the right hose for the application: Choosing hoses that are compatible with the hydraulic fluid, operating temperature range, and environmental conditions.

By understanding these common causes and implementing preventative measures, you can significantly extend the lifespan of your hydraulic hoses and reduce the risk of costly failures and downtime.

How to Protect Hydraulic Hoses

1. Hydraulic Hose Guards

Hydraulic Hose Spring Guards: These are coiled metal springs that encase the hose, providing excellent abrasion resistance and protection against kinking.

Benefits:

• High abrasion resistance
• Protection against sharp edges and debris
• Prevents kinking and twisting
• Durable and long-lasting

Applications: Ideal for use in harsh environments with high levels of abrasion, such as construction sites, mining operations, and heavy equipment applications.

Spiral Wraps: Flexible, often plastic, wraps that protect hoses from abrasion, cuts, and crushing. They can also help contain leaks in case of a rupture.

Benefits:

• Good abrasion resistance
• Protects against cuts and punctures
• Can help contain leaks
• Relatively easy to install

Applications: Suitable for a wide range of applications, including those with moderate levels of abrasion and potential for external damage.

Sleeves: Fabric or synthetic sleeves that cover the hose to protect it from abrasion, chemicals, and UV radiation.

Benefits:

• Protects against abrasion and cuts
• Can provide chemical resistance
• Protects against UV degradation
• Can improve hose appearance

Applications: Ideal for applications where chemical exposure, UV radiation, or a need for a more aesthetically pleasing solution is a concern.

2. Proper Routing and Installation

Avoid Sharp Bends: Excessive bending can weaken the hose and cause premature failure. Route hoses smoothly with gentle curves.

Guidelines:

• Use hose reels or guides to minimize sharp bends.
• Avoid routing hoses over sharp edges or corners.
• Provide adequate clearance for hose movement.
• Securely Mount Hoses: Use proper clamps and brackets to secure hoses to prevent chafing and movement that can cause damage.

Best Practices:

• Use clamps that are the correct size and type for the hose.
• Securely attach clamps to prevent loosening.
• Use brackets to support hoses at regular intervals.

Maintain Adequate Clearance: Ensure sufficient clearance between hoses and other components, such as moving parts or hot surfaces.

Considerations:

• Keep hoses away from heat sources.
• Avoid routing hoses near moving parts that could cause abrasion.
• Provide enough space for proper airflow around hoses.

3. Regular Inspection and Maintenance

Visual Inspections: Regularly inspect hoses for signs of wear and tear, such as cuts, abrasions, bulges, or leaks.

Frequency: Conduct visual inspections at regular intervals, such as daily or weekly, depending on the severity of the operating environment.

Pressure Testing: Periodically pressure test hoses to identify potential weaknesses.

Guidelines:

• Follow manufacturer‘s recommendations for pressure testing procedures.
• Use appropriate testing equipment.
• Document test results for future reference.

Replace Damaged Hoses Promptly: Replace any damaged hoses immediately to prevent further problems and ensure safety.

Importance:

• Do not attempt to repair damaged hoses.
• Replace hoses with the correct type and size.
• Follow proper installation procedures.

4. Consider the Environment

Extreme Temperatures: If operating in extreme temperatures, select hoses and protective measures that can withstand those conditions.

Considerations:

• Use hoses designed for high or low temperatures.
• Consider using heat shields or insulation to protect hoses from extreme temperatures.

Chemical Exposure: If exposed to chemicals, choose hoses and protective coverings that are resistant to those specific chemicals.

Guidelines:

• Consult with our hydraulic hose supplier to select the appropriate chemical-resistant hose.
• Use chemical-resistant sleeves or wraps to provide additional protection.

Abrasive Environments: In environments with high levels of abrasion, utilize robust protective measures like heavy-duty spring guards or abrasion-resistant sleeves.

Recommendations:

• Use high-quality spring guards with tightly wound coils.
• Consider using abrasion-resistant sleeves made from materials such as Kevlar or nylon.

By implementing these protective measures, you can significantly extend the lifespan of your hydraulic hoses, reduce the risk of failures, and improve the overall safety and efficiency of your hydraulic systems.
