What problems should be paid attention to in the selection and laying of compressed air pipelines?

Selection of materials for compressed air pipes

At present, many users are still using carbon steel pipes and galvanized pipes; After the carbon steel pipe has been used for a long time, there will naturally be corrosion impurities deposited inside the pipe, and eventually the pipe will be corroded and leaked.

Polluted air brings serious harm to the quality of equipment, instruments and end products, increases maintenance costs, and leaks directly waste a lot of electricity.

Therefore, the bulky and leaky carbon steel pipes and galvanized pipes have been slowly eliminated.

The new stainless steel compressed air pipes are the best choice for compressed air pipes due to their durability and air-free characteristics.

Problems that need to be paid attention to when laying compressed air stainless steel pipes

1. When piping, the main pipeline must be slightly skewed to facilitate the discharge of condensate in the stainless steel pipeline. The stainless steel pipeline should be equipped with a filter valve, and the sewage treatment should be discharged regularly.

2. The pressure of the piping pipeline should not exceed 5% of the set pressure of the compressor, so a larger pipe diameter should be used when piping.

3. The stainless steel pipeline should be shortened as much as possible and arranged in a straight line, and the application of elbows and various valves should be minimized to reduce the damage of pressure.

4. The pipeline of the branch line must be connected from the top section of the main road to prevent the condensate in the main line from flowing into the compressor unit along the pipeline.

5. The main pipeline does not have to be smaller or larger at will, if it must be smaller or larger, it must be matched with the gradual shrinkage tube, otherwise it is easy to think that the pressure increases, resulting in large pressure loss; In addition, due to the impact pressure of the gas, the service life of the pipeline will be greatly shortened.

6. It is necessary to fully consider the pressure loss caused by too long distance, that is, the problem of pressure drop. For factories with relatively many gas consumption points, annular gas supply pipelines can be laid, and the pipe diameter of the main pipeline can be thickened to two to three times the diameter of the air compressor inlet and outlet pipes. If necessary, the annular pipe can be retrofitted with an air compressor storage tank in the middle of the pipeline.

1. The stainless steel plate is very good, but the price is very expensive.

2. If the galvanized steel pipe is used, it will corrode, and it will be low.

3. With PPR, ** is vertically low, but it will break after a long time, which is not safe.

4. The new aluminum alloy profile pipe is non-corrosive, corrosion-resistant, slightly expensive and easy to install.

Shrinking tubes are commonly used in compressed air, auto parts stores and tilting (standard air punching) special tools, as well as water and non-corrosive liquid transportation, and are widely used in industrial production, construction industry, agriculture and animal husbandry and other industries.

Among them, the soft-walled compressed air pipe has the characteristics of shape, softness, ductility similar to vulcanized rubber, oxidation resistance, aging resistance, no acid and softness in summer, no hardening in winter, and no cracking.

Precautions: The bearing capacity of the compressed air pipeline support frame should be calculated by the corresponding mobile phone software, and under the allowable capacity standard, the support frame method should be selected as far as possible to limit the switch support frame, and the pipeline should be allowed to have radial deviation. In that way, in the case of the takeover section not long after, there is no support frame and pipeline compensator, and the simple loose fiber Changhua pipeline method reduces the cost of pipeline engineering and is also beneficial to the construction of the project on the spot.

Summary. Hello dear! Compressed air transmission pipelines need to be designed, oh kiss Generally, after compressed air is discharged, it needs to be transported to the use of air storage tanks and air compressor pipelines.

If there is a leak in the gas tank or if the compressed air piping is not properly designed, there will inevitably be a large waste. Key points of the design of the compressed air pipeline: 1. The pipeline should do a lot of preparatory work before laying, such as pipeline design, pipeline material selection, etc., the general pipeline design should use three-dimensional software modeling, after the three-dimensional model is built, it can directly generate the plan, isometric drawing, equipment table, material table, etc., which can save a lot of work in the later drawing, improve efficiency and ensure the accuracy of pipeline drawing.

Design points: The compressed air pipeline network diagram of the plant area, the starting point is generally the outlet of the air compressor in the plant area or the reserved contact point in the plant area, and the end point is each gas consumption point. If the conditions permit, the indoor and outdoor gas points of the entire plant area should be represented in the same plan or model axonometric drawing, that is, all the gas points of the entire plant area should be represented by a drawing, so as to facilitate drawing and review.

Kiss you and see if it solves your problem?

Do not use galvanized pipes, which will corrode after a long time, and use FST aluminum alloy pipes, which are specially designed to transport compressed air.

1. The one that uses stainless steel is the best, but it is very expensive. 2. The galvanized pipe will rust but it is cheaper. 3. With PPR, it is cheap, but it is unsafe to break in 3 years, and it is easy to have safety accidents.

4. At present, aluminum alloy pipes, emerging materials on the market, are not rusty, corrosion-resistant, zero leakage, expensive and quick to install.

New aluminum alloy compressed air pipeline.

If the compressed air is clean, ABS pipes should be used, which not only ensures the purity of the conveyed gas, but also ensures that the pressure drop of the whole system is less than bar, which is not possible with other pipes. Domestic standards for compressed pipes are outdated.

Details are available.

Oil-resistant rubber pads or rubber rings, PTFE gaskets are preferred.

Pipe selection: The pipe commonly used in compressed air pipelines is seamless steel pipes. Valves, pressure reducing devices, oil drainers, compensators, gas distributors and gauges are set up in the pipeline system, all of which are selected and processed according to the design drawings.

Pipes and fittings need to be visually inspected.

The pipes of high-pressure pipelines should be non-destructive tested using magnetic testing and other methods.

Pipes should be derusted and coated with anti-rust paint before processing, and valves should be cleaned, ground and hydrostatic tested.

The best and most energy-saving compressed air pipeline is PVR plastic steel pipeline, of course, we still need to pay attention to the length of the pipe and the number of connectors, so as to ensure efficient operation to the greatest extent! Recommend the self-owned brand fonter Fengtai plastic steel pipeline system to support domestic production!

It mainly depends on your pressure and use, such as industrial use, if the pressure is high, you can use seamless steel pipe or stainless steel pipe, if the pressure is low and for experiment, you can use plastic tube.
