Various Connection Options

Aqueous Caustic Soda, otherwise known as Lye, is a solution of Sodium Hydroxide (NaOH) in water commonly used throughout the paper, aluminium and chemical industry. One of its many uses is also in water purification and water treatment across the world. It is widely used as a cleaning agent within both the domestic and industrial sectors. Caustic Soda crystalises at a temperature of 7°C and therefore it is important that the liquid is stored in an ambient temperature of above 7°C or protected in heated or insulated tanks. Enduramaxx’s Industrial and Chemical Dosing Tanks, suitable for the storage of Caustic Soda / Sodium Hydroxide, are available supplied with external insulation as an optional extra.

Why Enduramaxx?

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).
