Techniques for selecting materials for compressed air pipelines in air compressors

The principle of compressed air pipeline is that high-pressure air generated by a compressor is transported through the pipeline to the equipment that needs to be used, and then released through the cylinder or air valve of the equipment to achieve the driving purpose of pneumatic equipment. In compressed air pipelines, the pressure, flow rate, and velocity inside the pipeline are very important parameters. Pressure refers to the air pressure inside the pipeline, usually set at 6.3 MPa, 1.0 MPa, 0.7 MPa, etc., and adjusted according to different needs. Flow rate refers to the volume of air passing through a pipeline per unit time, typically measured in cubic meters per minute, minutes per second, and liters per second. Speed refers to the rate at which air flows through a pipeline, typically set below 25 meters per second.

Compressed air pipelines are composed of compressors, pipelines, filters, air dryers, regulators, and joints. The compressor is the core of the entire system, producing compressed air and sending it into pipelines; Pipelines are responsible for transporting compressed air; Filters and air dryers are used to filter and dry compressed air; Pressure regulators are used to regulate the pressure of compressed air; The joint is used to connect the pipeline.

Techniques for selecting materials for compressed air pipelines in air compressors

1. Pressure resistance level: Compressed air pipeline materials need to have sufficient pressure resistance, so when choosing, it is necessary to check whether their pressure resistance level meets the actual requirements.

2. Corrosion resistance: Due to the harsh environment in which pipelines are often located in industrial sites, the corrosion resistance of materials is an important indicator when selecting. If the corrosion resistance of the material is poor, the service life of the pipeline will be affected.

3. Mechanical strength: During use, pipelines also need to withstand certain mechanical stresses, so when selecting materials, it is necessary to consider whether their mechanical strength is sufficient.

4. Thermal conductivity: The thermal conductivity of pipelines is also a factor to consider when selecting materials. A pipeline with good thermal conductivity can reduce the increase in air temperature, thereby reducing energy loss.

5. Easy installation and maintenance: The selection of materials also needs to consider the convenience of installation and maintenance, such as easy cutting and connection, easy installation and maintenance, etc.

Compressed air pipeline is a pipeline system used to transmit compressed air, which has a wide range of applications in many fields. For example, in the manufacturing industry, compressed air pipelines are used to drive pneumatic tools and mechanical equipment, and they are also used for industrial process control and instrument control. On construction sites, the presence of compressed air pipelines can also be seen, such as used for sand washing and mortar spraying. In the medical field, compressed air pipelines are used for ventilators and medical equipment.

After calculating parameters such as pressure, flow rate, and velocity, the length, diameter, material, and connection method of the pipeline can be designed. The length of the pipeline should conform to the range of use of pneumatic equipment, and the diameter of the pipeline should be adjusted as needed. The material can be selected from steel or plastic materials with good airtightness and easy maintenance. The connection method should ensure the firmness and corrosion resistance of the connection.
