High-quality graphite heat exchangers are mainly used for heating, cooling, condensation, evaporation and other operations of chemical plants. Widely used in chemical, food, pharmaceutical and other industries, in addition to strong alkali, strong oxidizing medium, can also be used for the treatment of hydrochloric acid, sulfuric acid, citric acid, pesticide intermediates. Graphite has good thermal conductivity, excellent corrosion resistance and no pollution to the medium, which solves the corrosion resistance of many equipment in the chemical industry. Graphite heat exchangers have largely replaced heat exchangers made of stainless steel or other precious metals.
C:Graphite heat exchanger classification
Graphite heat exchangers are divided into structural forms, which can be divided into various types such as tube type, block type, spray type, and immersion type. Among them, the most widely used are tube-and-block graphite heat exchangers. According to their application in the process, they can be divided into evaporators, heaters, coolers, condensers and so on.D: Tech Data |
