Use of graphite heat exchangers
Release time:
2021-05-16
Before opening, please clean the debris in the graphite heat exchanger process tube to prevent clogging the graphite holes. Graphite heat exchanger factory try to minimize the downtime of the equipment to a large extent and prolong the service life of the equipment. When the heat transfer capacity of the equipment is reduced, the inspection should be stopped. If the graphite heat exchanger plant is heavily scaled, it can be cleaned by appropriate physical and chemical methods; if the tubes are blocked due to crystallization, they can be heated and melted for cleaning.

Since graphite is a fragile material, mechanical processing is prohibited. The upper and lower parts of the housing are equipped with exhaust pipes. When installing the equipment, the valves should be installed first and then connected to the exhaust pipe. The use of blinds is strictly prohibited. Before using the equipment, the exhaust valve at the top of the enclosure should be opened and the air in the enclosure should be completely removed before sealing. During use, non-condensable gases at the top of the shell side and condensate at the bottom are often vented. The larger the particle size of the graphite matrix, the less dense the material and the lower its mechanical strength. The larger the particle size, the more through holes may be exposed when drilling and the porosity will increase.
To obtain the desired fineness, the amount of impregnant added will affect the quality of the impregnation and the heat transfer properties of impermeable graphite. The higher the concentration, the higher the mechanical strength. Therefore, the use of high-density substrates after the impregnation heat treatment has ceased, the consumption of processing equipment, quality stability and safety are high and the use is effective. Impregnants for heat transfer equipment are filled with graphite-based materials. Different impregnants have a direct effect on the corrosion resistance of impermeable graphite. Different impregnation amount will affect the use temperature and corrosion resistance level of impermeable graphite.
