What material is used for compressed air pipeline

Large amount of compressed air leakage: compressed air leakage is almost a common waste of energy in factories. In China, the average amount of compressed air leakage accounts for 30% of the total amount of compressed air, and what is particularly serious is that the field management personnel far underestimated the damage caused by the leakage. For example, a hole in the pipe with a diameter of 1mm caused by the corrosion of acidic oil in the gas can cause a loss of up to 3,500 KWH of electricity every year, almost equivalent to the annual electricity consumption of two families of three.

Compressed air pipeline said, the air compressor power consumption is serious waste: usually, in order to make the output pressure fluctuation is small, many compressors use suction valve regulation. This method still needs to consume 70% of the rated power without gas supply, which is a serious waste. In addition, due to the uncertainty of pipeline pressure loss and the presence of peak flow when the equipment is started, the air supply pressure of the screw air compressor is sometimes higher than the pressure required on site by 0.2 ~ 0.3mpa, which is very serious waste. Sometimes, for a few devices with high pressure requirements, the overall gas supply pressure will be increased, which is unreasonable in energy use and configuration.

The function of the air dryer is to further remove moisture from the compressed air to meet certain requirements for the user of the compressed air. At present, the commonly used methods of compressed air drying include adsorption method and freezing method. The function of the oil and water separator is to separate the oil and water in the compressed air, so that the compressed air can be preliminarily purified. The commonly used oil and water separator has three types of structure: annular rotary type, impact folding type and centrifugal rotary type.

Compressed air pipelines generally choose welded steel tubes, galvanized steel tubes and seamless steel tubes for low-pressure fluid transportation, or choose according to design requirements. Nominal diameter less than 50mm, can also use thread connection, with white lacquer hemp silk or ptfe raw material tape as packing; The nominal diameter is greater than 50mm, it is advisable to connect by welding.

Pipe bend should be used as far as possible, the bending radius is generally 4D, not less than 3D. When branch pipe is drawn from the main pipe or main pipe, it must be drawn from the top of the main pipe or main pipe and connected to the ground 1. 2 to 1. A air distributor is installed at 5m and a hose joint is installed on the air distributor. The pipeline shall be set at least 0 according to the direction of airflow. Slope 002, the end of the main pipe should be set water collector.
