In pneumatic systems, pneumatic accessories (such as joints, pipes, valves, cylinders, etc.) play an important role in transmitting and controlling airflow. Reasonable selection of the material of pneumatic accessories can not only improve the reliability of the system, but also extend the service life and reduce maintenance costs. This article will compare and analyze the common materials of pneumatic accessories to help users choose the most suitable material.
1. Pneumatic pipelines
Aluminum alloy pipes: light weight, corrosion resistance, suitable for medium pressure systems.
Stainless steel pipes: suitable for high pressure, high temperature or food grade scenes, such as pharmaceuticals and food processing.
Nylon pipes / polyurethane pipes: good flexibility, suitable for general industrial pneumatic systems, but not resistant to high pressure.
2. Pneumatic valves
Aluminum alloy valve body: commonly used in general pneumatic control systems, taking into account weight and strength.
Stainless steel valve body: suitable for harsh environments, such as humid, high temperature or corrosive gas environments.
Brass valve body: mostly used for precision control valves to ensure sealing and corrosion resistance.
3. Pneumatic connectors
Stainless steel connectors: suitable for high pressure and high temperature environments, with excellent durability.
Brass connectors: suitable for low pressure systems with high sealing requirements, with strong anti-oxidation ability.
Plastic connectors (POM, nylon): suitable for low pressure systems, easy to install, but with low pressure resistance.
4. Cylinders
Aluminum alloy cylinders: lightweight design, widely used in automation equipment.
Stainless steel cylinders: suitable for humid, high temperature and high pressure environments, such as medical and food processing.
Carbon steel cylinders: suitable for industrial heavy loads, but need to be rust-proofed.
According to the use environment: Stainless steel or brass is recommended for humid and corrosive environments, and aluminum alloy or plastic can be selected for general industrial environments.
According to the working pressure: Stainless steel or carbon steel is recommended for high pressure systems, and nylon or plastic can be selected for low pressure systems.
According to the cost budget: Aluminum alloy and plastic accessories are cost-effective and suitable for standard pneumatic systems; stainless steel is suitable for high-demand occasions, but the cost is higher.
The material selection of pneumatic accessories directly affects the safety, durability and cost of the system. Different materials have their own advantages and disadvantages. Users should make choices based on the use environment, pressure level, and corrosion resistance requirements. Choosing a professional pneumatic component manufacturer can not only obtain more reliable products, but also enjoy professional technical support to ensure the long-term stable operation of the pneumatic system.
