The application of high-pressure air compressors in the airtightness testing industry is very extensive and important, mainly reflected in the following aspects:

1. Airtightness testing of high-pressure vessels or pressure vessels: High pressure air compressors provide high-pressure gas for various high-pressure vessels such as gas cylinders, steel cylinders, valves, pipelines, pressure instruments, high-pressure boilers, etc., for airtightness testing, pressure testing, strength inspection, and verification. These tests are crucial for ensuring the safety of the container.

2. CNG natural gas vehicle modification pipeline testing: In the field of CNG natural gas vehicle modification, high-pressure air compressors are used to perform airtightness testing and sealing inspection on car cylinders, car pipelines, pressure reducers, regulators, mixers, natural gas injection devices, natural gas flanges, etc. This helps ensure the safety and reliability of the modified automotive piping system.

3. Aerospace field: In the aerospace industry, high-pressure air compressors are widely used in gas supply for wind tunnel testing, ground gas source support equipment, and pressure and airtightness testing platforms. These applications are crucial for the design and manufacturing of aerospace vehicles.

4. Petrochemical industry: In the petrochemical industry, high-pressure air compressors are used for air passivation of urea reactors, ammonia pressurization storage, hydrogen purging, and respiratory air supply in factory emergency systems. At the same time, it is also used for airtightness testing of various high-pressure vessels or pressure vessels.

5. Other fields: In addition to the above-mentioned fields, high-pressure air compressors are also widely used in the energy industry (such as airbag filling, emergency generator start-up), food industry (such as volume increase of powder products, nitrogen packaging, stirring of oil-free food blowing gas), mechanical manufacturing and factories (such as pressure testing of containers, pipelines and valves) and other fields. In these fields, high-pressure air compressors also play an important role in air tightness testing.

In summary, high-pressure air compressors play a crucial role in the airtightness testing industry, with a wide and in-depth range of applications. By providing high-pressure gas for airtightness testing and pressure testing, high-pressure air compressors help ensure the safety and reliability of various equipment and containers.
