There are several factors can affect the service life of hydraulic hoses. Key factors include:

1)Working Pressure: Exceeding the recommended working pressure may place excessive stress on hydraulic hoses, causing premature failure. It must be ensured that the pressure in the hydraulic system remains within the recommended limits.

2)Temperature: Extreme temperatures, both hot and cold, can affect the performance and life of hydraulic hose. Excessive heat can cause the hose to degrade, while extreme cold can make it more prone to cracking and stiffness.
3) Fluid Compatibility: The type of fluid used in a hydraulic system can have a major impact on the life of the hose. Certain fluids, such as highly corrosive or abrasive fluids, can accelerate hose material degradation.
4) Flexibility and bends: Hydraulic hoses are designed to withstand flexibility and bends, but excessive and repeated bends can weaken the hose and lead to failure. It is important to ensure that the hose is properly installed and routed to minimize stress and bending.

5) Abrasion and External Damage: Exposure to rough surfaces, sharp edges, or abrasive materials can cause abrasion and external damage to the hose, resulting in leakage or rupture.
6) Proper protection, such as hose guards or sleeves, can help prevent this type of damage.
7) Maintenance and Inspections: Regular maintenance and inspections are critical to identifying any signs of wear, damage, or deterioration in hydraulic hose. Prompt replacement of worn or damaged hoses can prevent unexpected failures and downtime.
8) Age and Use: Over time, hydraulic hoses will naturally deteriorate due to age and use. It is important to monitor the life of the hose and replace it according to the manufacturer's recommendations.
By considering these factors and taking proper maintenance measures, you can maximize the service life of hydraulic hoses and ensure the safe and efficient operation of hydraulic systems.
