What’s Steel tank (cylinder)
The steel tank in scuba diving refers to the pressurized cylinder that holds the breathing gas (usually a mix of compressed air or enriched air nitrox) that divers use underwater. These tanks are commonly made of steel, although there are also aluminum tanks.
Steel tanks are favored for their durability and resistance to damage, making them suitable for various diving conditions. They come in different sizes and capacities, measured in terms of cubic feet or liters, to accommodate different air volumes based on the dive requirements.
Divers secure the steel tank to their BCD (Buoyancy Control Device) via a tank strap, ensuring it remains stable during the dive. The valve on the tank allows divers to control the airflow and manage their breathing underwater.
In summary, the steel tank is a critical component of scuba diving equipment, serving as the vessel for the breathing gas that enables divers to explore the underwater environment.
