If all storage conditions are satisfied, liquid nitrogen in a pressurised tank will remain there for years. No matter the time, the tank maintains the correct pressure and volume. It will always be prepared to act quickly (if the valves work).
Your pressure tank should be examined every five years to make sure it is functional and ready for usage.
Your pressure tank has to be taken out in the following situations:
- It’s bare (before they reach 30 bar)
- You think there may be gas leaks
- There are traces of damage or alterations to the tank
- If your pressure regulator is malfunctioning
Therefore, if you think there may be a problem with your pressure tank, it should be changed and examined by professionals. Always keep in mind that employing a subpar pressure tank might be risky for both you and your customers.
