Heat Exchanger Plate for Corrosion Reasons

　The heat exchanger plate for corrosion failure type

　　Heat exchanger to stress corrosion cracking: the metal caused by the cathodicdissolution process under the combined effect of static tensile stress and electrochemical media, local corrosion cracking or fracture. Pressing plate willproduce a residual internal stress, with the halide ions in the media (such as Cl -, F -ions) or H2S exposure may cause stress corrosion cracking;

　　Heat exchanger to intergranular corrosion: the origin at the surface of the metal along grain boundaries deep into the internal corrosion that can lead to loss of binding force between the grains, so that the strength of the material greatly reduced.Example, stainless steel corrosion in allergic temperature range (400 ° C to 600 ° C);

　　Heat exchanger uniform corrosion: metal surface contact with the medium all or most of the corrosion phenomenon. For example, the plate improper selection, or use oflong, more than the allowable life of;
