Abstract:
A process for manufacturing a chemical device element comprising at least one first assembly part and at leant one second coated assembly part, each said coated assembly part comprising a metal support part and at least one anticorrosion metallic coating, said process comprising the following successive steps:A manufacturing two or more intermediate coated assembly parts by a brazing operation comprising: (i) forming an initial assembly comprising a support part, an anticorrosion coating and at least one brazing material between the support part and the coating; (ii) introducing the initial assembly into a controlled-atmosphere brazing chamber, (iii) forming a controlled atmosphere in said chamber; (iv) heating said assembly up to a temperature at least equal to the brazing temperature of said brazing temperature of said brazing material, in such a way as to fix the anticorrosion coating on the support part by brazing; B shaping said intermediate coated parts, by plastic deformation, in such a way as to obtain said first and second coated assembly parts; C assembling the coated assembly parts, in such a way as to obtain said chemical device element.
