What happens if we do not hydro test our cylinders?

The cylinder undergoes hydrostatic testing with the purpose of checking whether it can safely hold its rated pressure. Hydrostatic testing is critical when it comes to compressed gas containers because they can explode in case if they fail when containing compressed gas.

What is the difference between Hydrotest and hydrostatic test?

Hydrotesting is another pressure testing option where a liquid (usually water) is injected into a pipe system to check for structural flaws permitting leakage. Hydrostatic testing allows the detection of leaks that only become obvious at elevated operating pressures.
