What are the typical pressures used for hydrostatic testing and airtightness testing?

How is it expressed in the standards? I seem to remember there being an API~ How is its specific content defined? Thank you
(What are the typical pressures used for hydraulic testing and airtightness testing?) ) Based on your requirements, it’s actually a pressure test; pressure testing is safer than a airtightness test, and leaks will occur to the extent specified
It seems to be about checking the pressure rating of the equipment. The equipment pressure rating is multiplied by a coefficient.
Go and consult experts in equipment or piping; they know best
It seems to be 1.5 times the normal pressure. It’s better to check the relevant standards for accuracy
There is a pressure grading: for normal airtightness tests, the pressure is 1.1–1.15 times the nominal value, while for hydrostatic tests it is 1.25–1.5 times. This approach does not apply to high-pressure systems; the specific requirements need to be checked in the design specifications.
Many of the instruments purchased by our company require pressure and airtightness test reports; I’m not sure which standard provides detailed instructions on this
Also, is this pressure 1.5 times the normal operating pressure, or 1.5 times the designed value? ?
It should be 1.5PN to 2.0PN.
The hydrostatic test is conducted at 1.25 times the normal operating pressure, rather than the design pressure; water pressure is safer than air pressure
The water pressure should be 1.5 times the design pressure, while for airtightness it’s around 1.25 times. Airtightness poses a serious risk, especially in high-pressure systems
