Production process of food additive sodium hydroxide – what are the material requirements for alkali pipelines?
Thread Content
The production process of the food additive sodium hydroxide – what are the specific materials used for the pipelines, valves, and storage tanks related to this alkali? Can materials such as nickel, CPVC, low-calcium magnesium adhesive, stainless steel, and fluorinated coatings be used in the production of the food additive sodium hydroxide?
Could there be a better material than this?
The material selection depends on the specific operational requirements: for applications where corrosion is not an issue but cleanliness is important, high-grade sanitary stainless steel or materials lined with PFA, etc., should be chosen
Sure, you can find the production requirements for food additives; they should be available there, at the Food and Drug Administration.
