Plate heat exchangers are common heat exchange equipment in civil and industrial heat exchange systems. The takeover is an important part of the heat exchanger, and the installation requirements are relatively strict.

The following is a brief introduction to Propellent editor's notes on the installation and takeover of plate heat exchangers:

1. The connecting pipe should be flush with the inner surface of the flange;
2. The inlet and outlet of the cold and hot medium of the pipeline should be consistent with the connection of the heat exchanger. Considering the convenience of maintenance, it is best to use a short section when connecting the pipeline and the heat exchanger;
3. The connecting pipe should be set as far as possible along the radial or axial direction of the plate heat exchanger;
4. When the temperature requirement is higher than or equal to 300 ℃, butt welding flange should be used;
5. If necessary, thermometer interface, pressure gauge interface and liquid level gauge interface should be set;
6. For heat exchangers that cannot take over (or interface) for deflation and liquid discharge, the air discharge port should be set at the high point of the equipment, and the liquid discharge port should be set at the low point. The minimum nominal diameter is 20mm;
7. Plate type heat exchanger can be equipped with overflow port.
When installing and operating the plate heat exchanger, you should understand the installation and operation rules and precautions in detail, ensure the normal and smooth operation of the plate heat exchanger during use, and try to avoid the damage to the heat exchanger caused by damage to the parts .
