You know what are the plate cooler corrosion?
Nov 14, 2016

Cooler for use after a period of time we will see the spots appear on the surface, in fact, this would mean that the cooler has been eroded, this is just a very common phenomenon, plate cooler and crevice corrosion, stress corrosion cracking, intergranular corrosion, corrosion and so on.

Cooler corrosion means stainless steel sheet metal surface rust or scale, thermal conductivity of bad, medium PH value by leading local passivation film on metal surfaces have been destroyed, causing localised corrosion, corrosion this battery also known as occlusion, perforation of the average performance is less than 1mm or pits.

Cooler basis block battery corrosion, crevice corrosion is caused by a mottled or ulcers localized corrosion, but this is mainly in the metal parts of the gap, so called crevice corrosion, corrosion is mainly due to detention caused by electrochemical inhomogeneity of the medium.

Stress corrosion cracking of oil cooler is the cooling plates and other products in the manufacture of forming residual stresses when, under static tensile stress and under electrochemical media such as halide ions, by cathode caused localized corrosion of metals dissolved in the process of crack or fracture phenomena.

Oil cooler intergranular corrosion originated from the metal surface and grain boundary corrosion of internal, such as the stainless steel in the temperature range of 400-600 ℃ will result in corrosion, the corrosion can cause the grain loss of adhesion, makes the material strength is greatly reduced.

Corrosion of cooling: cooling plate materials used improperly or too long, has exceeded its service life, contact medium appears most if not all of the metal surface corrosion phenomena, it is corrosion, in order to avoid the corrosion cooler selection to proper service life exceeded must be promptly replaced.

Cooler when corrosion has reminded us that product functions begin to decline, when used to pay attention to safety. Some hope that we can keep in mind above, so that you can better maintain the product.
