Medium and materials not suitable for glass lined reactor

The glass lined reactor has strong corrosion resistance and stability under high pressure and high temperature environments, making it widely used in the chemical industry, suitable for production materials containing various concentrations of organic acids, inorganic acids, organic solvents and weak bases and other media or materials Chemical processes such as reaction, polymerization, storage, and heat exchange. However, it does not have defensive capabilities against some chemical raw materials, which are roughly as follows:

　　 1. Hydrofluoric acid of any concentration and temperature, and media or materials containing fluoride ions;

　　2. Glass lined reactor is not suitable for hydrofluoric acid of any concentration and temperature and medium or materials containing fluoride ion;

　　 3. Phosphoric acid media or materials with a concentration greater than 30% and a temperature greater than 180°C;

　　 4. The hydrochloric acid medium or material with a concentration of 10-20% and a temperature greater than 150°C;

　　 5. Sulfuric acid media or materials with a concentration of 10-30% and a temperature greater than 200°C;

　　 6. Alkaline media or materials with a pH value greater than 12 and a temperature higher than 100°C;

　　 7. The reaction process of alternating acid and alkali materials.

　　 Please keep in mind that the above several chemical raw materials are not suitable for glass lined reactors, and should avoid reacting with them, otherwise it will cause corrosion damage and other problems, causing unnecessary safety problems or economic losses.
