Tubular Heat Exchangers are widely used for heat exchange of liquids or gases. Their daily maintenance is essential to ensure efficient, safe and long-term operation.
First of all, it is necessary to regularly check the exterior to see if the shell and tube sheet are corroded, cracked or deformed, to ensure that the flange connection is tight and leak-free, and that the support and supporting structure are stable and not loose or damaged.
Cleaning and descaling work is essential. The tube bundle should be cleaned regularly according to the properties and flow of the medium used. Chemical cleaning agents or physical methods such as high-pressure water jets can be used to remove scale and sediment, while ensuring that there are no debris in the shell and tube.
The operating parameters need to be monitored, and the temperature and pressure of the inlet and outlet media should be recorded to ensure that they are within the design range. If there are abnormal changes, it may indicate that there is a problem with the equipment. It is also necessary to pay attention to the stability of the medium flow to prevent the heat transfer efficiency from being reduced or the equipment from being damaged due to flow problems.
The seals should be checked frequently to check whether the gaskets and seals are intact. If they are damaged or aged, they should be replaced in time. At the same time, the valves and instruments should be normal and not leaked or damaged.
Do a good job of maintenance, fault records and document management. There should also be a regular maintenance plan, and professionals should be invited for complex maintenance. At the same time, emergency plans and spare parts management plans should be formulated. In short, doing these maintenance points well can extend the life of the equipment and ensure its efficient and safe operation. If you encounter any problems, you can consult professional technicians.
