Understanding LOX tanks (1)
A cryogenic LO2 (liquid oxygen) tank is a specialized container designed to store oxygen in its liquid state at extremely low temperatures. Liquid oxygen is oxygen that has been cooled to around -183°C (-297°F), where it becomes a pale blue liquid. This liquefaction reduces the volume of oxygen by about 860 times compared to its gaseous state, making it more convenient for storage and transportation.
### Key Features of Cryogenic LO2 Tanks
1. **Insulation**: To keep liquid oxygen at its cryogenic temperature, these tanks are equipped with advanced insulation systems. Common methods include vacuum insulation or multi-layered insulation (MLI) to minimize heat transfer and prevent the liquid from evaporating.
2. **Material**: The construction of LO2 tanks requires materials that can withstand extremely low temperatures without becoming brittle or losing structural integrity. Typically, they are made from high-grade stainless steel or aluminum alloys designed for cryogenic applications.
