Graphite Electrodes Electrolysis With 4TPI Nipple
graphite brick and carbon brick are widely used as the lining material in various of high temperature furnace or chemical equipment. In many chemical processes, the equipment and reaction vessels must be protected against the acidic and caustic materials used in the processes. The linings made from ceramic or synthetic plastic type materials are often unsuitable, since they may not withstand chemical attack, high temperature or sudden temperature changes. Alkaline solutions and hydrofluoric acid are of great importance in chemical technology, but they rapidly destroy equipment linings not made of carbon containing materials.
