Difference between low pressure and high pressure tanks.
Scuba tank sizes and pressures.
The information below was compiled from a variety of sources including luxfer pressed steel tank catalina and oms.
Steel scuba tanks are denser than aluminum tanks meaning you have to be less concerned with buoyancy issues especially at the end of a dive.
The 2640 psi low pressure steel tanks are preferred by nitrox and technical divers who expect to be blending their gases using the partial pressure method.
The most common service pressures seen in modern scuba tanks are 2640 psi 3000 psi 3300 psi 3442 psi and 3500 psi.
For example most aluminum tanks from the smallest 6 cuft pony bottle to an 80 cuft tank have a fill pressure of 3000 psi.
The difference between pressure volume it should be noted that the pressure of a tank is not a measure of the size or volume of a tank.
For a 6 cuft bottle this means at 3000 psi the tank contains 6 cuft of air.
Scuba tanks are rated to hold a maximum pressure given in pounds per a square inch the higher the pressure the more compressed the air inside the tank is and the stronger or thicker the tank walls must be to safely contain the air.
While steel and aluminium scuba tanks come in a wide range of sizes see above the following are the most commonly used sizes.

High pressure steel tanks will have a pressure range between 3300 psi to 3500 psi 227 240 bar.
Most aluminum scuba tanks are rated for 3000 psi.

The information is believed to be accurate but is not guaranteed.
A drawback of high pressure scuba cylinders is that they require more metal to maintain the higher amount of compressed air inside.
A diving cylinder scuba tank or diving tank is a gas cylinder used to store and transport the high pressure breathing gas required by a scuba set it may also be used for surface supplied diving or as decompression gas or an emergency gas supply for surface supplied diving or scuba.
Divers who engage in very deep or long dives may prefer tanks with a greater.

Smaller than an aluminum tank of the same capacity a steel scuba tank is a more compact air supply solution a fact that becomes doubly important for twin tank setups.
Cylinders provide gas to the diver through the demand valve of a diving regulator or the breathing loop of a.
High pressure tanks allow for a large gas capacity in a smaller size.
