What factors affect the pressure and durability of the air hose?

Air hose is an indispensable component in pneumatic tools and equipment. Its performance directly affects the efficiency and safety of the entire pneumatic system. The pressure and durability of the air hose are key indicators and are affected by many factors. Understanding these factors can help users choose the right air hose and ensure its optimal performance during use.

1. Material selection
The material of the air hose is an important factor affecting its pressure and durability. Common air hose materials include rubber, polyvinyl chloride and polyurethane.
Rubber air hose: High temperature and wear resistance, suitable for heavy and high-pressure applications. Its elasticity and strength enable it to maintain good performance in high-pressure environments.
PVC air hose: Lightweight and economical, but weak high-pressure resistance, suitable for low-pressure applications. For higher pressure environments, PVC air hoses may deform or rupture.
Polyurethane air hose: Has good flexibility and low-temperature resistance, suitable for frequent moving occasions. It has good wear resistance, but still needs to be used with caution under high pressure.
It is crucial to select materials suitable for specific applications to ensure the stability and durability of the air hose under working pressure.

2. Inner and outer diameters
The inner and outer diameters of the gas pipe directly affect its flow rate and pressure resistance. The larger the inner diameter, the greater the gas flow rate, which can better support high-pressure operations; but too large an inner diameter may cause the gas flow rate to decrease, affecting the performance of the tool. The outer diameter is related to the strength of the gas pipe. The gas pipe with a larger outer diameter usually has better pressure resistance.
Reasonable selection of the inner and outer diameters of the gas pipe can improve the pressure resistance while ensuring the flow rate and extend the service life of the gas pipe.

3. Working pressure
The working pressure of the gas pipe is an important indicator affecting its durability. Each gas pipe has its maximum pressure resistance. If this limit is exceeded, the gas pipe may rupture, deform or age. Therefore, during use, be sure to follow the pressure range provided by the manufacturer and avoid frequent pressure fluctuations, which can effectively extend the service life of the gas pipe.

4. Temperature influence
The temperature resistance range of the gas pipe is another key factor. High temperature environment will cause the aging of the gas pipe material and reduce its pressure resistance; while low temperature may make the material brittle and increase the risk of rupture. Therefore, choosing a trachea with good temperature resistance and using it in a suitable temperature environment can effectively prevent the performance of the trachea from deteriorating.

5. Use environment
The use environment of the trachea also has a significant impact on its pressure and durability. Common environmental factors are as follows.
Humidity: A high humidity environment may cause the trachea material to absorb water, affecting its performance, especially PVC materials are more susceptible to moisture and deformation.
Chemical substances: When the trachea comes into contact with oil, solvents or other chemicals, it may degrade or deteriorate. Therefore, avoid contact between the trachea and these substances, or choose chemically resistant materials.
Mechanical damage: During use, the trachea may be rubbed, squeezed or impacted by objects, causing wear or rupture. Therefore, reasonable layout of the trachea to avoid contact with sharp objects can effectively reduce the risk of mechanical damage.

6. Maintenance and care
Regular maintenance and care are essential to extend the service life of the trachea. It is recommended that users regularly check whether the trachea is worn, aged or leaking, and replace it in time if necessary. Keeping the trachea dry and avoiding high temperature and high pressure environments can effectively improve its durability.

The pressure and durability of the Air Hose are affected by many factors, including material selection, inner and outer diameters, working pressure, temperature, operating environment, and maintenance. Understanding these influencing factors can help users make more reasonable decisions when selecting and using air hoses, thereby ensuring the efficient and safe operation of the pneumatic system. Through scientific management and maintenance, users can maximize the service life of air hoses and provide reliable support for various pneumatic operations.
