How To Quickly Determine The Corrosion Of Cooler For Engineering
Jun 22, 2017

Cooler for Engineering use after a period of time we will find its surface spotted, in fact, this means that the Cooler for Engineering has been corroded, this is only a very common phenomenon, the Cooler for Engineering also has crevice corrosion, stress corrosion cracking, intergranular corrosion, uniform corrosion and so on a series of phenomena. Next you'll find out more about:

Cooler for Engineering Pitting:

Refers to the stainless steel sheet metal surface rust or fouling, so that the poor heat conduction, the ph of the medium reduced, such as the local metal surface of the passivation film has been damaged, causing the local corrosion, this is also known as block battery corrosion, generally shown to be less than 1mm perforation or pitting.

Condenser Crevice Corrosion:

A spot-shaped or ulcer-shaped localized corrosion is caused by the corrosion of the occluded battery, but the corrosion is mainly caused by the crevice of the metal parts, so the corrosion of the crevice is called, which is mainly due to the electrochemical inhomogeneity of the stranded medium.

Stress corrosion cracking of Cooler for Engineering:

Cooler for Engineering plates and other products in the production of molding will produce residual internal stress, in the static tensile stress and halogen ions, such as the interaction of the electrochemical medium, from the cathodic dissolution process caused by the metal local corrosion crack or fracture phenomenon.

Intergranular Corrosion of Cooler for Engineering:

is due to the metal surface and along the grain boundary depth to the internal corrosion, such as stainless steel in the 400 temperature range will produce corrosion, this corrosion will lead to the loss of adhesion between the grains, so that the strength of the material greatly reduced.

Uniform Corrosion of Cooler for Engineering:

Cooler for Engineering plate selection or use time too long, more than its service life, can contact the metal surface of the medium will appear most or even all of the phenomenon of corrosion, which is even corrosion, in order to avoid this corrosion, the Cooler for Engineering material selection should be properly, the service life is more than the timely replacement.

Once the Cooler for Engineering has been discovered, it has already alerted us that the product function has started to fall and that it is safe to use. The above several phenomena hope that everybody can remember, can quickly judge, so that you can better maintain Cooler for Engineering.
