You need to understand the knowledge points of airtightness test
Why do we need to conduct an air tightness test after the pressure parts and pressure volume are completed? Is there a good testing method and procedure? What are the requirements for stress?
Regarding the above issues, the editor will discuss them in detail with everyone.
Why do we need to conduct an air tightness test?
Airtightness test is a gas sealing test conducted on pressure volume and pipelines to prevent local defects such as sand holes and cracks in the produced products. It uses gas as a medium and pressurizes it to enter the interior of the tested product. For pressure vessels and pipelines storing hazardous gases, special gases, and high-purity gases, airtightness tests must be conducted. It is a different experimental method from air pressure testing that is essential for protecting personal safety.
Is there a good testing method and procedure?
At present, the detection method is generally based on the different pressure levels of pressure vessels, shells, pipelines, and valves, selecting different air tightness test pressures for testing. If the customer's on-site pressure is not enough, the Fuente gas booster pump can be used for boosting and inspection. The inspection methods are generally divided into pressure drop method inspection (observing the pressure gauge), bubble detection (more intuitive), digital pressure control, and computer control.
Air tightness test steps, (1) water pressure test - (2) air pressure test - (3) air tightness test
Only after conducting water pressure and air pressure tests can air tightness tests be carried out
What are the pressure requirements for air tightness testing?
