Heating reactors are commonly used in petroleum, chemical, rubber, pesticides, dyes, pharmaceuticals, foods, pressure vessels used to complete the processes of vulcanization, nitration, hydrogenation, alkylation, polymerization, condensation, and other processes. According to the heating method of the reaction vessel, it can be divided into a steam heating reaction vessel and an electric heating reaction vessel, and the heat conduction oil heats the reaction vessel. According to the different types of reactor seals can be divided into: packing seals, mechanical seals and magnetic seals. The stainless steel reactor has the characteristics of rapid heating, high temperature resistance, corrosion resistance, sanitary, no environmental pollution, no need of automatic heating of the boiler, convenient use, etc. It is commonly used in petroleum, chemical, rubber, pesticide, dye, medicine, food, etc. Complete the vulcanization, nitration, hydrogenation, alkylation, polymerization, condensation and other processes.
