The effect of flow velocity in the heat exchanger on its service life
Thread Content
Carbon steel heat exchanger, with an organic liquid as the medium; its viscosity is similar to that of water. The operating temperature is around 100 degrees, and the operating pressure is below 30 bar. When the flow rate is ≥3, the impact of flow rate on the service life of the heat exchanger – I welcome experts to share their insights!
Excessively high flow rates can cause severe erosion of the equipment itself and the welds, and over time the equipment will be damaged beyond repair.
It’s not clear which flow rate you are referring to: the flow rates in the pipe, between pipes, at the nozzle, and so on are all different. A flow rate of 3m is not considered high. I think the key points are: 1. Preventing the entry of moisture and other impurities, as well as chemical corrosion caused by changes in the composition of the material itself ； 2. Prevent cavitation caused by excessive temperature and high pressure drop ； 3. Prevent local erosion caused by unreasonable structure
Reply to floor 4: The flow rate refers to the flow velocity in the pipeline before the device’s inlet; the flow area at the device’s outlet is twice that of the flow area in the pipe section.
