Plate heat exchanger corrosion protection measures (
First of all, we must take account of plate heat exchanger in media corrosion ability, and accurate selection panel data.
External passivation of stainless steel plate, on the surface oxide film formed on the solid and very thin film, thereby gaining excellent corrosion resistance.
In the planning of plate heat exchanger plate forming mould, should choose the structure of the small residual stress.
In order to reduce the plate heat exchanger plate the surface scratch, must be the outer surface of the polishing the mold.
Sheet and gasket with glue.
Don't use expired, and adhesive with high chloride.
Increase the rate of plate heat exchanger plate contact contact, in order to reduce damage to contact.
