Oxygen tank

An oxygen tank, also known as an oxygen cylinder, is a container that stores oxygen gas under pressure. These tanks are commonly used in various applications, including: 1. **Medical Use**: They provide supplemental oxygen for patients with respiratory conditions, such as chronic obstructive pulmonary disease (COPD), asthma, or during recovery from surgery. 2. **Industrial Use**: In industries like welding, oxygen is used in conjunction with fuel gases to create high-temperature flames for cutting and welding metals.
