Heat exchanger is widely applied in a general equipment in chemical, petrochemical, power, medicine, metallurgy, light industry, refrigeration. Type heat exchanger is various, according to the heat transfer surface shape and structure can be classified into the tube type, plate type heat exchanger and other types, such as spiral heat exchanger, tube heat exchanger, tube heat exchanger, heat exchangers, coil heat exchanger, condenser, cooler, the chlorine cooler, heater, heat exchanger, the mother liquor evaporator reboiler, crystalline external cooler, our production manufacturing all kinds of heat exchangers, mainly used for strong corrosive conditions, according to the use conditions, medium user corrosion strength, titanium, nickel, selection of tantalum and other special materials, effective to improve the anti-corrosion performance and the working efficiency of the equipment, the following specific parameters of ordinary tubular heater:
