What happens when the compressed air line changes from one diameter to another?

Compressed air lines should be laid along short routes to minimize bends, especially sharp ones. The pipeline shall be equipped with necessary fittings, such as switch and reverse valve installed between the air compressor and the air storage cylinder, switch to be installed between the air storage cylinder and the total 3.

When a pipe changes from one diameter to another, the diameter shall not be changed suddenly. In the same pipe line, it is not allowed to have one small diameter pipe installed between two large pipes, or intermittent installation of different sizes of pipes.

The analysis of media components and magazines in dalian compressed air pipeline is not clear enough, and there is a lack of necessary magazine cleaning equipment. As a result, the vulnerable parts of the pipeline are scoured seriously and the pipeline life is shortened, as well as the valve, equipment and other faults, damage and leakage occur. The design pressure of the pipeline was increased without considering the actual conditions such as the quality of the pipe and the construction level.

Due to the influence of hot air, the accumulated carbon in the air compressor pipe continues to oxidize. When the speed of hot air airflow slows down, it will lead to the relative increase of exhaust temperature. At this time, the heat absorbed by carbon deposition oxidation is far more than the heat released by carbon deposition. Therefore, it will enter the state of automatic heating, which then leads to the spontaneous combustion of carbon deposition.

The cause of air leakage is usually due to the poor quality of materials and accessories or installation, the support sinking in the pipeline causes serious deformation and cracking of the pipeline, the water inside the pipeline will freeze and burst the pipe or pipe fitting, etc.
