Caustic Soda / Sodium Hydroxide Storage Tanks
Chemical & Impact Resistant
Various Connection Options
Caustic tanks need to be specialized to survive long storing Caustic Soda. Caustic soda is also known as sodium hydroxide, caustic, and lye. Caustic soda, as a 50% solution, is an odorless and colorless liquid. In all forms, caustic soda is highly corrosive and reactive. Caustic soda solution reacts readily with metals such as aluminum, magnesium, zinc, tin, chromium, bronze, brass, copper, and tantalum. Galvanized (zinc coated) materials should be avoided. Contact with acids, halogenated organics, organic nitro compounds, and glycol should be avoided. It reacts with most animal tissue, including leather, human skin, and eyes. It also reacts readily with various reducing sugars (i.e., fructose, galactose, maltose, dry whey solids) to produce carbon monoxide. Upon cooling, the viscosity of the solution increases rapidly as the temperature falls below 65°F (18°C).
