The selection of compressed air pipeline materials shall comprehensively consider the compressed air quality, pressure level, environmental corrosion and other factors, and follow the relevant national standards. The following are specific selection specifications and basis:
| Material Type | features | applicable Scenarios |
|---|---|---|
| carbon steel pipe | strong and durable, easy to shape, low cost; but easy to rust, need regular maintenance | industrial scenarios with low quality requirements for compressed air (such as air supply for general pneumatic tools) |
| galvanized pipe | corrosion resistance, rust prevention and beautiful appearance; However, it is easy to rust after the galvanized layer is damaged. | Building or industrial applications with limited budgets and low air quality requirements |
| aluminum alloy pipe | light weight, easy processing; but the surface oxide layer is easy to corrode after damage | lightweight or specific corrosive environment (such as salt water environment) |
| stainless steel pipe | excellent anti-rust, corrosion resistance, high temperature resistance; high cost | high-standard industries (e. g., pharmaceuticals, electronics, precision manufacturing) |
| plastic pipes (PVC, etc.) | easy to install, low cost; but poor corrosion resistance, easy to aging | temporary or low demand scenarios (need to be replaced regularly) |
Industry case: A pharmaceutical factory adopts 304L stainless steel pipe and oil-free air compressor to stabilize the dew point of compressed air at -40 ℃, reduce the microbial contamination rate by 92%, and reduce the equipment maintenance cost by 45%.
Permanent magnet screw air compressor, as a screw air compressor that combines permanent magnet motor technology and frequency conversion speed regulation technology, has the advantages of high efficiency, energy saving, stability and reliability, and is widely used in various industries and production fields. The following is the main use of permanent magnet screw air compressor
Should be able to calculate the pressure vessel, the general air compressor is conjoined with a gas storage tank, the gas storage tank is a pressure vessel. If the air compressor is an oil-free screw machine, there is no need to consider the pressure vessel inside the machine, because it does not have an oil and gas separation cylinder. If it is spray
The water-lubricated air compressor does have an air-cooled type. Water-lubricated air compressors can be divided into water-cooled and air-cooled according to different cooling methods. The working principle of the water-lubricated air compressor is that during the compression process, water is injected into the main engine through the water lubrication system to perform
Compressed air, as an important infrastructure of the modern medical system, undertakes multiple key functions in the ward environment, which is directly related to the safety of patients and the quality of medical care. Comprehensive technical analysis and industry practice
Oil and no oil refers to whether the compressed air contains oil. Oil air compressor is by the compressor special oil and air mixing, compression, separation into the purification equipment. Oil-free means that there is no lubricating oil in the compressor cavity. It is possible to lubricate with water or
When selecting an air compressor, the following key parameters need to be considered to ensure that the selected equipment can meet production requirements and operate efficiently: 1. working pressure (exhaust pressure) Definition: Working pressure refers to the highest exhaust gas of the air compressor Pressure, also known as exhaust pressure. Unit
Shanghai Granklin Group is a well-known brand in the air compressor industry, with a wide range of products and advanced technology. The group provides a variety of types of air compressors to meet the needs of different customers, including water-lubricated air compressors, oil-free air compressors, frequency conversion air compressors, screw
The soft start and frequency conversion start of screw air compressor are two different starting methods, and there are significant differences in the starting principle, functional characteristics and application effect. The following is a detailed comparison of these two start methods: 1. start principle Soft start principle:
Shanghai Granklin Group and its oil-free low-pressure screw air compressor have performed well in the industry and are one of your preferences. The following is a detailed analysis: 1. Shanghai Granklin Group strength enterprise background: Founded in 2009, it is located in Shanghai Baoshan District Robot Industrial Park, accounting
To solve the problem of water in the air compressor pipeline, we can start from the following aspects: 1. analysis of the causes of water first, it is necessary to clarify the causes of water in the pipeline in order to take targeted measures. Common reasons include: insufficient cooling of air compressor: causing water vapor in
