Heat exchanger gasket
Heat exchanger gasket
(OP)
I have to design a U tube STHE. The pressure drop across pass partition plate is 0.5MPa. Can I design it without pass partition gasket. I am planning to provide an o ring at the periphery only. Tube side fluid is water with Temperature rise from 6 to 7 degree Celsius shell side it is air with temp drop from 150 to 10 degree celsius.

Back to designing your gasket when you say "Pass Partitions Gaskets" are you referring to water separators located in the header? And What is your operating pressure and test pressure?
Is the pressure drop on the water-side? 0.5MPa or 72 psi

Pass partition: The channel is partitioned into to two by a pass partition plate. My question whether gasket is required in between pass partition plate and tube sheet.
Pressure values
Shell side 0.5 bar test pressure 1 bar
Tube side(Water) 5 bar and test pressure 7.8 bar
Tube side pressure drop is correct only

on the water side. Therefore, the Lanier path on the waterside will be reduced.

That burns all of the available pressure on the water stream. How do you get 5bar dp on a single pass only in any case? What velocity are we running at on the tubeside for the water stream ?
Agree with your concern on tubeside interpass leakage at 5bar dp, but something more basic is wrong here.
