The air compressor pipeline configuration and installation are summarized. The pipeline installation requirements, the connection and arrangement of the air pipeline, the anti-corrosion of the air pipeline, the lightning protection of the air pipeline, and the pipeline pressure loss are summarized in detail.

1. Requirements for pipeline installation
1). The air supply port of the unit has a threaded connection, which can be connected with your air supply pipeline. Please refer to the factory manual for installation dimensions.
2). In order to avoid affecting the operation of the whole station or other units during overhaul, and to reliably prevent compressed air from flowing back during overhaul, a shut-off valve must be installed between the unit and the air tank.
3). In order to avoid affecting the air consumption during filter maintenance, spare pipelines should be provided on each filter pipeline.
4). The branch pipeline must be connected from the top of the main pipeline to prevent the condensed water in the pipeline from flowing into the compressor unit.
5). The pipeline should be as short as possible and straight, reduce elbows and various valves to reduce pressure loss.
2. Connection and arrangement of air pipelines
1). The main pipeline of the compressed air machine pipeline is 4 inches, and the branch pipeline should use the existing pipeline as much as possible.
2). Generally, the pipeline should have a slope greater than 2/1000, with a drain valve (screw plug) at the lower end, and the pipeline should have fewer bends and short straight valves.
3). When the pipeline below passes through the main road, the buried depth of the pipe top is not less than 0.7m, and the secondary road is not less than 0.4m
4). The installation position and surface size of the pressure and flow meters should enable the operator to see the indicated pressure clearly, and the pressure scale range should be such that the working pressure is 1/2 to 2/3 of the dial scale.
5). After the system is installed, it should be tested for air pressure strength and air tightness, and not for water pressure test. It is carried out at 1.2 to 1.5 times the pressure of the same gas, and no leakage is qualified.
3. Anti-corrosion of air pipeline
After the installation is completed and the pressure test is qualified, after removing the surface dust, dirt, rust spots, welding slag, etc., paint for anti-corrosion treatment. The pipeline painting has the effect of anti-corrosion, extending the service life of the pipeline, and is also easy to identify and beautiful. Generally, apply the anti-corrosion paint once on the surface first, and then apply the specified blending paint.
4. Lightning protection of air pipeline
Once the high-voltage electricity induced by lightning in the pipeline is introduced into the workshop pipeline system and gas equipment, it will cause equipment personal safety accidents. Therefore, the pipeline should be well grounded before entering the workshop.
5. Pipeline pressure loss
When the gas flows in the pipe, frictional resistance is generated in the straight pipe section; local resistance is generated at the valve, tee, elbow, reducer, etc., resulting in gas pressure loss.
