Cryogenic Valve Testing and Inspection

2025-01-14

The main parts of the cryogenic valve are subjected to low temperature treatment and low temperature impact test is performed on each batch of samples to ensure that the valve does not crack under low temperature conditions and can withstand the impact of low temperature media.

The following tests are performed on each valve:

1. Normal temperature shell strength test;

2. Normal temperature low pressure upper seal test;

3. Normal temperature low pressure seal test;

4. Low temperature upper seal airtightness test (when there is an upper seal);

5. Low temperature airtightness test, etc., to ensure that the entire cryogenic valve meets the requirements of the standard;

6. The main parts are subjected to low temperature treatment and low temperature impact test is performed on each batch of samples to ensure that the valve does not crack under low temperature conditions and can withstand the impact of low temperature media;

7. Low temperature (deep cold) valves are subjected to low temperature treatment and impact test according to the corresponding material specifications;

8. The anti-static function is more powerful, and the conduction resistance between the valve body and the valve stem or the internal parts and the valve body is less than 1 ohm.
