The relationship between pipeline pressure drop and pipeline diameter of air compressors

The air compressor pipeline is one of the most important components of the compressed air system. Without high-quality gas transmission pipelines, the vast majority of compressed air systems will not work properly. For air compression systems, the precautions for air compressor pipelines include pressure drop, anti fouling, rust prevention, etc.
(1) What is the pressure drop of the air compressor pipeline
The outlet pressure of the air compressor is inconsistent with the terminal gas pressure, and the reason for the pressure difference lies in the compressed air pipeline. When compressed air passes through the pipeline system, the friction with the pipeline will cause it to lose some pressure during its journey, which is called pressure drop.
(2) The relationship between pressure drop and diameter of air compressor pipeline
The smaller the diameter of the air compressor pipeline, the longer the distance the air travels, the greater the friction it experiences, and the slower the speed, which means there is a greater pressure drop.
(3) Other factors affecting the pressure drop of air compressor pipelines
There may be valves, elbows, connectors, etc. in the air compressor pipeline system, which can lead to an increase in pressure drop. In addition, leaks, damages, etc. at pipeline connections can also lead to increased pressure drop. Therefore, in order to greatly reduce pressure drop, it is necessary to avoid setting elbows, tees, and valves on the pipeline as much as possible.
In compressed air systems, pressure drop is one of the factors that consume energy and costs for enterprises. As is well known, we can reduce gas transmission resistance and pressure drop by selecting larger pipe diameters, but excessive pipe diameters can increase investment costs for users. Therefore, the pipe diameter should be suitable.
