Stainless Food and Caustic Soda Tanks

Caustic Soda skin texture and eyes should be tiring and careful. Appropriate warnings, safety showers and eye wash stations should be located in all areas where Caustic Soda is stored or used. It is highly recommended that the Caustic Soda be processed by trained personnel wearing long-sleeved garments and equipped with eye-protective goggles, rubber gloves, body gowns, masks and other safety equipment when needed. In addition, the staff of the Caustic Soda management need to know that when water is added caustic solution, significant heat will be formed.

Caustic Soda is normally handled and stored in iron or steel containers and at temperatures above 15 ° C under 55 ° C and at temperatures higher than 55 ° C. Stainless steel, nickel and Monel 400 is recommended to handle Caustic Soda at high temperatures. It is also good practice to tear caustic soda in high temperature conditions in tanks covered with an organic metal. At temperatures below 15 ° C, the Caustic Soda solution will start freezing. If the temperature drops below 15 ° C, you need to supply the heating to the caustic tank.

Liquid caustic soda is a corrosive product. Liquid caustic soda is stored at certain kinds of steel, nickel, nickel alloys or plastics at the time of the water. The preference is determined by the temperature, concentration, tank location, safety problems and end use. Austenitic stainless steel AISI 304L Suitable for temperatures up to 70 ° C. AISI 304/316 / 316L is also sufficient, but to a lesser extent.

Stress relaxation with a corrosion allowance is not important if the iron content in the uncoated soft steel end product is suitable, and the storage temperature is not higher than 45 ° C. Good compromise between carbon content between 0.18 and 0.25% ductility / weldability and stress cracking resistance. . Stress cracking or caustic fragility If the liquid temperature is above 45 ° C, unleaded soft steel may be formed.
