Scuba diving tanks are the most essential part of a diver’s gear. These tanks basically have the role of keeping you alive while underwater, and their construction, durability and steady pressure are extremely essential traits and qualities that will help make your diving experience as smooth and convenient as possible. Diving tanks are generally made from sturdy, lightweight metal, such as aluminum, and are utilized by divers through the help of rebreather systems and diving regulators that are meant to offer stability and safety when it comes to the actual supply of breathing gas provided.
Diving tanks are most often made out of aluminum, but they can also be built from steel for added support, or in order to withstand higher pressures. The reason why diving tanks are made to supply air under high pressure is a simple one: a greater amount of lifesaving breathing gas can fit in a small tank, offering divers a handy, practical and easy to carry portable source of oxygen. To make sure your diving tanks are as easy to use and safe as possible, it is important to make sure they are made from high grade aluminum or steel, feature proper specification for the amount of time they can be used before the air supply is depleted, and are also fitted with proper harnesses.
The scuba tank is more than just a container with a lot of air under high pressure. It is a complete system designed to fit conveniently on the diver’s body, and to conveniently be attached to the diving regulator system, so there are never any issues or dangers during its use. Special valves and sturdy DIN screw thread or A-clamp/yoke connectors may be needed for that purpose. Additional accessories, such as scuba tank holders and mesh protectors, also have the role of keeping tanks securely in place and properly protected during each dive.
Scuba diving tanks come in all shapes and sizes, and their design is quite simple, yet extremely practical in offering divers the kind of air supply they can survive off of for several hours at a time. The tanks are made to be extremely sturdy, in order to withstand pressures ranging between 184 and 300 bars (2,670 – 4,350 psi). Depending on whether they are used as standard tanks carried by divers, emergency air supply or breathing gas supplied from the surface, the tanks’ capacity can range between as little as .5 liters and as much as 18 liters. Most of the time, quality scuba diving tanks are fitted with air; however, in some instances, other types of breathing gasses are also added to help counter the problems created by regular air supplied under high pressure underwater environments.
When choosing a tank, capacity is important, of course, as the more air you get the better, but more capacity means bigger size and increased weight too, so keep these aspects in mind. Your body size and strength will determine how big “too big” is – thus, always try on the scuba diving tanks before selecting one.
