Shipbuilding industry in the field of shipbuilding is mainly concentrated in the sandblasting, painting, sanding gas, for different volume requirements have the traditional centralized air pressure station room gas supply and container into a skid of mobile equipment needs; In the field of shipboard equipment application, the drying purification system puts forward more stringent requirements, especially the FPSO shipboard equipment is more stringent.

The electronic industry for compressed air usage and demand are not low, compressed air is mainly used in airflow transportation, instruments and pneumatic tools (sorting, packaging, testing, handling, assembly, etching and other instruments or pneumatic applications), instrumentation air, nitrogen production (high-purity nitrogen welding), electronic components cleaning, clean room.

The automotive manufacturing field has a considerable demand for compressed air, of which the requirements of the automotive spraying line are even more stringent, usually requiring oil-free compressed air with a pressure dew point of -40 ℃ or less, and often also requiring a silicone-free filtration system. The quality of the compressed air directly determines the final paint effect.

Different types of wind tunnel test air (room temperature, supersonic, ultra-low temperature wind tunnels), wind tunnel test air, especially ultra-low temperature wind tunnels for compressed air performance requirements for the harsh, that is, the need to achieve a dew point of -70 ℃ below the low-pressure situation, but also need to ensure that the CO2 content of less than 5 ppm; in addition to this, compressed air has been used for aircraft surface spraying, power, instrumentation, and fuel filling protection gas In addition to this, compressed air is also used for aircraft surface coating, power, instrumentation and fuel filling protection, etc.

The food and beverage industry has certain requirements for the quality of the air used, often in the equipment materials, filtration and sterilization, etc. There are also many uses for compressed air, some of which involve contact with food. There are many uses of compressed air, some of which are related to food contact, mainly used in instrumentation, pneumatic conveying of materials, bottle blowing (PET bottle blowing pressure is generally used in 35-45bar), bottling / canning, packaging, filling, liquid mixing and so on.

Iron and steel metallurgy, as a large user of compressed air, has been paying more attention to energy saving of compressed air in recent years. From equipment replacement to energy-saving renovation, the original intention of carbon reduction and emission reduction remains unchanged. General compressed air use in the steel industry is concentrated in the instrumentation air, pneumatic conveying and sintering air. Steel mills usually have steam conditions, and the use of steam to achieve further energy savings has been carried out by Risheng for more than 20 years.

Compressed air in the petrochemical industry is mostly used for instrumentation, pneumatic conveying, fermentation, waste gas treatment, dehydration and drying, etc. Some of them will involve material requirements, and some of them will put forward the overall skid structure requirements.

Taking new energy vehicle batteries as an example, batteries require the use of a large number of lithium-ion cells. Each cell contains several parts, such as anode, cathode and electrolyte. Compressed air covers a wide range of processes, from raw material handling to the preparation of the core material.

Pharmaceutical industry compressed air is mostly used in the production process: mixing and granulation, drying, tableting, packaging, removal of bottling / filling environment of moisture, etc., most of the air requirements for Class 0 high purity oil-free, dust particles and moisture content also has a not too low requirements, and the production of compressed air related to the basic requirements of stainless steel; will also be used for instrumentation air, compared to the requirements of the relatively broad The requirements are relatively broader.

From test rigs, robotic arms and laser cutting to precision instruments, solenoid valves and pneumatic tools, the quality of compressed air affects not only the process, but also the service life of the air-using equipment itself. A compressed air system that is low in oil, dust and humidity can extend the life of equipment components.
