Why do you need to repair and maintain the heat exchanger?
In oil refining and chemical production, some of the media passing through the heat exchanger contain coke and other deposits, and some are corrosive. Therefore, after the heat exchanger is used for a period of time, fouling and rust will accumulate in the flow-through parts such as heat exchange tubes and the shells. This reduces the heat transfer efficiency on the one hand, on the other hand reduces the flow cross section of the tube and increases the flow resistance, even causing blockage. In addition, the corrosion of the medium will also make the tube bundle, shell and other parts damaged. The long-term vibration and uneven heating of the equipment will cause leakage at the expansion joints and other connections of the pipe. These will affect the normal operation of the heat exchanger and even force the shutdown of the device. Therefore, the daily maintenance of the heat exchanger must be strengthened, and regular inspections and repairs must be carried out to ensure the normal production.
