What are the characteristics of compressed air pipeline material selection

When the compressed air pipeline is equipped with pipes, the main pipe must be slightly tilted to facilitate the discharge of condensed water in the pipe. Pipeline should be equipped with sewage valve, and regularly sewage. The pressure of the pipe line shall not exceed 5% of the set pressure of the compressor. Pipeline should be as short as possible and straight, as far as possible to reduce the use of elbow and various valves, in order to reduce the loss of pressure.

The atmosphere contains corrosive gases, water vapor, hydrocarbons and other impurities, each cubic meter of air is mixed with about 140 million solid particles, more than 80 percent of these impurities are less than 2 microns in diameter, so will easily through the air compressor and filter, into the compressed air system

The pipelines of branch lines must be connected from the top of the main line to prevent the condensed water in the main line from flowing to the compressor unit along the line. The main road should not be arbitrarily reduced or enlarged, if it must be reduced or enlarged with a shrinking tube, otherwise it is easy to think that the increase in pressure, resulting in a large loss of pressure; At the same time, the impact pressure of the gas will shorten the life of the pipeline.

All the compressed air conveying pipelines in domestic factories and enterprises are linear and unidirectional, which will cause the front-end working position to work normally and the pressure and flow supply of the back-end working position to be insufficient. In addition, during installation and design, the installation of sectional control valves was not considered, and the failure of one area or one equipment would cause the whole plant to stop production and miss work. In the installation, the drainage problem is rarely considered. The compressed air delivery pipes of many enterprises are very messy, including those flying in the air and those buried underground, which are intricate and unable to drain water

Consider the loss of pressure, or pressure drop, over long distances. For factories with relatively more gas points, the annular gas supply pipe can be laid, the diameter of the main pipe should be enlarged to 2 to 3 times of the outlet diameter of the air compressor. A gas storage tank may be installed in the middle of the pipe when necessary.
