how to read a scuba tank

The upper edges of all scuba tanks are engraved with a series of marks that convey important information about the tanks being used.
It is good to know what these marks indicate, as this knowledge can help to rule out the issue of renting tanks.
If you are planning to buy your own tanks and other diving equipment, it is especially important to know how to read scuba tanks.
Description difficulty: it is easy to check the top line of the mark.
In this line, you will find a Mark marked with \"points\" followed by a number and two letters.
This means that the tank has been certified by the United States. S.
Ministry of Transport.
The letters below will tell you what the tanks are made of, 3A and 3AA indicate steel and AL means aluminum.
The aluminum is lighter and the steel is more durable.
Check the next line (i. e.
, The row closest to the valve opening).
This line contains what you think is the legacy of the tank because it will tell you where it came from and who made it.
From left to right, the first item listed is the thread specification.
This is important knowledge if you buy a valve as you need to get a valve that matches the tank.
The second project is the country of manufacture, usually abbreviated (e. g. , US).
Next is the serial number of the tank.
It is important to note that because you can use it to track the manufacturing history of the tank by contacting the manufacturer to ensure that the model you are using does not have any major defects.
Check the third row.
Here you will find important specifications for tanks.
The first is the minimum thickness of the tank, in millimeters or inches, according to the manufacturer\'s standards.
Next is the weight of the tank when it is empty.
After that is the capacity of the tank.
If the water tank is using a rice system, it measures the capacity in the form of a liter of water, while in the imperial system it measures the capacity using cubic feet of compressed air.
The next number is crucial because it is the maximum capacity that the tank should be filled with per square inch (
Or pressure bar).
The final figure is slightly higher, indicating the maximum pressure the tank should be filled with for testing purposes.
Learn about the history of tanks.
The last line enables you to understand the history of a particular tank, which is very important for safety.
Some tanks will have another pressure number, but there is a temperature behind this pressure number.
This shows the maximum pressure that the tank can withstand at a certain temperature or above.
Next is the date of the original water pressure test on the tank, followed by the date of the most recent test.
This is critical knowledge because tanks have to be tested every five years to make sure they are still structurally sound enough to handle air pressure.
