for hi P. steam exhaust of turbine(belonged to a big cooling water centrifugal pump) it is supposed a surface condenser, but why dose it limit us for keeping the subcooling max 3 degree centigrade? is it because of dissolved O2 in the condensate?

note that our outlet condensate temp is 81degree C with o.5 bara pressure

It is now clear who is asking for the limit of 3 degrees. Is it the turbine manufacturer, surface condenser manufacturer, or someone else?
I assume the condensate is being pumped. Is it the condensate manufacturer that is asking for the limit?
I would think from a heat conservation standpoint, you would want to keep it as close to the condensing temperature as possible and still be able to pump the condensate.

To stop the condensate from turning to ice and blocking the outlet with consequential pressure build-up.

Sorry, but I think you may have the wrong web site.
