Think what happens when you pop a balloon filled with air then THINK what happens when you pop a water filled balloon One causes a violent reaction an the other just plops apart .
Then look up the ASME or NBBI codes and and then ask yourself why is STEAM considered HIGH PRESSURE @15 PSI or more and why is a hot water boiler considered HIGH Pressure @160 PSI or 250 DEG Temp.
Once you have a semi decent understanding of the various codes then it will come to you why professionals try to use hydrostatic testing when possible..
ALSO Note that during an "air test" as the ambient temperature rises so does the test pressure as there is something called pressure /temperature relationship. Higher temperature creates higher pressure

What is the sequence for hydro testing internally coated valves?
The sequence for hydro testing internally coated valves typically involves the following steps: First, ensure the valve is clean and free from any debris or contaminants. Next, connect the valve to the hydro test setup and fill it with water, ensuring that all air is purged from the system. Then, gradually pressurize the valve to the specified test pressure while monitoring for leaks. Finally, maintain the pressure for a designated duration before safely depressurizing and inspecting the valve for any signs of failure or coating damage.
How will you test starter and choke in fluorescent tube?
You can use a wire instead of the starter to test the tubes .. I did it, it works !
What is the code that require a Pipe Hydro Test Package?
The code that typically requires a Pipe Hydro Test Package is the ASME B31.3, which governs the design and construction of process piping. This code mandates hydrostatic testing as a means to verify the integrity and leak-tightness of piping systems. Additionally, other codes such as ASME B31.1 for power piping may also have similar requirements. Compliance with these codes ensures safety and reliability in piping systems under operational conditions.
What is the aim of doing polarity test on the transformer?
Knowing the polarity of transformers is important if they are to be connected in parallel.
What is the role of mechanical inspection engineer?
Doing NDT inspection,thorough examination,load test etc
What is hydro test and hydro static?
A hydro test is a test used to determine the strength and integrity of a pressure vessel or piping system by filling it with water and pressurizing it to a specified level. Hydrostatic refers to the resulting pressure that is exerted by a fluid at rest due to gravity.
Difference between hydro test and hydrostatic test?
A hydro test is a type of pressure test that involves filling a vessel or system with water and pressurizing it to ensure it can safely hold the intended pressure. On the other hand, a hydrostatic test is a specific type of hydro test that involves using water as the test medium and pressurizing the system to a specified pressure for a set period to check for leaks or structural weaknesses. In essence, a hydrostatic test is a subset of hydro tests, with the key difference being the use of water as the test medium and the specific test parameters involved.
Calculate volume of water for hydro-test?
To calculate volume of water for hydro test you need to use the formula pi times radius (squared) times length. Pi is equal to 3.14.
What is hydro test pressure?
A test pressure whcih is used to perform hydro test is known as hydro test pressure, besically the hydro test pressure is more then the design pressure of pipe, tank, pressure vessel ..................

How do you get hydro codone out quickly?
Drink lots of water. Vinegar mixed with water can alter test results, but i will warn it can cause nausea.
Can you use water instead of urine for a drug test what will the results be.?
you'll get disqualified for trying to cheat the test
How do you calculate air inclusion during hydro test?
To calculate air inclusion during a hydro test, you would measure the volume of air bubbles released during the test using a calibrated container. The volume of air collected can then be compared to the total volume of water used in the test to determine the percentage of air inclusion. This can help assess the integrity of the system being tested.
Can pickle do the trick for a drug test?
Yes, for two months prior to your drug test, instead of doing drugs, eat a pickle. You'll pass your test. Shave your head if it is a hair test.
In iodoform test can you use ethanol instead of water?
No, you should not use ethanol instead of water when conducting the iodoform test. The test relies on the reaction of iodine with an alcohol in the presence of a base, typically sodium hydroxide, to form iodoform. Water is usually used in the test to help facilitate the reaction. Substituting ethanol for water can affect the outcome of the test.
What is a hydro test?
Pressurizing the vessels with water up to test pressure and checking for any leakage to insure the soundness of pressure vessels and its capacity to withstand pressure without any permanent deformation
