How to maintain and service shell and tube heat exchangers
Author:
Summary:
Currently, with the widespread application of heat exchangers in various industries, shell and tube heat exchangers occupy a significant portion of the market, especially playing an extremely important role in the energy sector. To enable shell and tube heat exchangers to operate more efficiently, regular maintenance and upkeep have become an essential part.
Currently, with the widespread application of heat exchangers in various industries, shell-and-tube heat exchangers occupy a significant portion of the market, especially playing an extremely important role in the energy sector. To enable shell-and-tube heat exchangers to operate more efficiently, regular maintenance and upkeep have become essential.
1. First, we need to install a filtration device at the point where the fluid medium enters the shell-and-tube heat exchanger, which can effectively enhance water quality and reduce the occurrence of mud, scaling, and corrosion within the heat exchanger.
2. If cracks have developed in the connections between the tube bundle and the tube sheet, leading to failure, we need to repair it using methods such as re-expanding, welding, or expanding and welding.
3. If the heat exchange tubes are already damaged, we should first use the pipe blocking method for emergency repair. However, in most cases, the number of blocked pipes should not exceed ten percent of the total number of pipes. Therefore, if too many heat exchange tubes are damaged, they should be replaced.
4. We need to inspect the heat exchanger to identify areas that are prone to scaling. Then, based on the different components and degrees of contaminants and dirt, we should formulate corresponding maintenance measures.
5. When the working environment temperature is below 0°C, we must clean and drain the medium and circulating water from the heat exchanger to avoid the occurrence of frozen and cracked pipes.
6. The heat exchanger should undergo chemical cleaning at regular intervals.
