摘要

"The process of deposition of a coating of alumu00ecnio or an alloy of alumu00ecnio - silu00eccio through thermal spraying with subsequent diffusion by heat treatment and welding bimetu00e1lica extremities in I.Nternos tubes ".Particularly, a process that has as objective is the protection of such tubes and piping components (curves, nipples reductions.Tees and caps) furnace corrosion naphthenic, bringing a series of extraordinary advantages for processes or technologies currently employed.In this process the coating is applied on the inside of a tube (1) or connections through the technique of thermal spraying.In an area previously prepared through lowering of the extremities, welds and by abrasive blasting using aluminium oxide brown with a high degree of purity, and.Once prepared, receives the pipe or connection (1) the coating of aluminium or aluminium alloy silicon (4) by thermal spraying, and then the same heat-treated, and once that was done,The ends of the tube connection or suffer a procedure for welding capable of generating a region of union bimetu00e1lica with root pass (5) on the inner side and external finishing and filling (6).
