Increase in let and out let Pipe Dia. Can usfull?

Increase in let and out let Pipe Dia. Can usfull?

Increase in let and out let Pipe Dia. Can usfull?

(OP)
We have the problem for our cooling water system.
Look like not enough flow through the exchanger.
Then the big boss enforce us to increase inlet and outlet pipe dai but exchanger still same cap and sizing.
In case. Can make benifit or nor ? And what should be?

RE: Increase in let and out let Pipe Dia. Can usfull?

Depends on how much dP is in the inlet/putlet piping dosnt it?

To some extend increasing the flow will of course help but not indefinetely. Maybe its time to clean the exchanger?

Best Regards

RE: Increase in let and out let Pipe Dia. Can usfull?

Have you checked all of the simple things? It's always disappointing to make expensive changes then find out something like the unit has been piped for parallel flow rather than counterflow. There isn't a big bubble of non-condensibles trapped on one side, is there? I've seen people spend a lot of time and money only to find out there's a manual valve someplace that wasn't fully opened, or a pump with a 3-phase motor is rotating backwards.

If this were my project, I'd make sure that there are thermometers and pressure gauges installed across the inlet and outlet piping on both sides of the heat exchanger. The manufacturer of the HX should be able to provide accurate flow data for his unit based on the pressure drops across it. Once the flows are known, it's a simple matter to use the thermometer readings to calculate how much heat is being transferred.
