Plate heat exchanger corrosion protection measures (
The first thing to consider data can make medium corrosion, accurately choose plate heat exchanger plate materials.
The plate heat exchanger of stainless steel plate surface passivation treatment, the oxidation film appearance generates a layer of density of fast and very thin film, thus won the outstanding corrosion resistant function.
In the planning of plate heat exchanger plate forming dies, should choose the structure of the residual stress is small.
To reduce the scratch of plate appearance, want to polishing mold appearance.
Plate heat exchanger plate and gasket binder, don't choose expired and rich in chlorine root binder.
Choose reasonable accurate plate tectonic and normal velocity.
Add the plate heat exchanger plate contact contact rate, reduce damage to contact.
