Glass-lined Equipment
 

[Properties] Glass lining equipment is made by coating high silicon content enamel on the metal tire surface, then hot dipping at 950℃. It is widely used as the substitute of stainless steel and non-ferrous metal in chemical industry, medicine and dyestuff, pesticide, organic synthesis, petroleum, food processing, defense industry and other science research and development.
The product is erosion resistant to inorganic acid, organic acid, organic solvent and weak base in various concentration, while it is not available for alkali, hydrofluoric acid and the medium with fluorine and the phosphorous acid, whose temperature is 180℃ above and the concentration is 30% above.
