Equipment for pressure vessel airtightness testing
Thread Content
Apart from the relatively expensive testing equipment such as helium leak detectors and ammonia leak detectors, are there any devices that can be used to test the airtightness of ordinary air? By devices of this kind, I mean those that do not require a person to apply soap solution or similar substances, and that can detect leaks through pressure or other methods
A regular airtightness test uses a pressure level that is similar to that used in testing, just at a lower pressure; no special equipment is required
Is it okay to put the tire in water to check for leaks?
It depends on whether it’s a normal-pressure vessel or a pressure vessel; testing for leaks with water in a normal-pressure vessel won’t work
It depends on your requirements regarding airtightness. For example, if it’s difficult to repair the container in case of leaks or if there are safety hazards, it’s better to follow strict standards; it doesn’t matter if the cost is higher, as otherwise there will be costs associated with repairs and modifications. Let me give an example. For low-temperature double-layer storage tanks, helium leak testing is performed on the inner tank, while bubble leak testing is used for the external pipelines. Routine leak detection, airtightness testing, helium leak detection, ammonia leak detection, and halogen leak detection. If there are no special requirements regarding the water medium, the tank can be placed in water to check for leaks by observing whether bubbles form.
It’s difficult to find equipment that can check airtightness without using soapy water
If the container is not large, simply soak it in water for testing
There is no definition of what \"not very large\" actually means
Not very large – it just means you’ve dug a pool that is big enough. .
