The pipe ends of the heat exchanger are too small
Thread Content
The factory wants to use an old heat exchanger. The liquid flow rate is 150 m3/h, and the inlet and outlet of the heat exchanger are DN65. The calculated flow velocity is 13 m/s – is this sufficient? What to do if the pipe opening is too small?
What medium? If it’s a gas, 13 m/s isn’t considered fast!
Reduction joint, converted to DN150
The liquid flow rate is too high; the tube bundle is being severely eroded. Cut it out and weld it again
Your topic isn’t very clear. Are you trying to determine whether the flow rate obtained through expansion is sufficient to reach the desired flow rate? The tube sheets and heat exchange tubes must have fixed dimensions; if not, it will be necessary to redesign and produce new equipment
