Manufacturing process for an element of a chemical device comprising a support part in metal and an anticorrosion metallic coating

Manufacturing process of an element of a chemical device comprising at least one first and one second coated assembly parts, each said coated assembly part comprising a metal support part and at least one anticorrosion metallic coating, said process comprising:

• manufacturing intermediate coated assembly parts according to a process comprising a brazing operation comprising:
• forming an initial assembly comprising a support part, an anticorrosion coating and at least one brazing material between the support part and the coating;
• introducing the initial assembly into a controlled-atmosphere brazing chamber;
• forming a controlled atmosphere in said chamber;
• heating said assembly up to a temperature at least equal to the brazing temperature of said brazing material, in such a way as to fix the anticorrosion coating on the support part by brazing;
• shaping of said intermediate coated parts, by plastic deformation, in such a way as to obtain said coated assembly parts;
• assembling the coated assembly parts, in such a way as to obtain said element of a chemical device.
