Resumo (PT): In this paper it will be described a procedure to repair a steel pipeline, using steel-patches bonded to the "old" pipeline in certain weak points. Significative pressure may occur, hence particular care has to be taken when repairing the points under pressure. The philosophy used to establish the repairing procedure, the variables considered (ie. Surface place preparation, cure conditions, ...) and the joint design are points which will be described. A brief description will be made considering the laboratory tests carried out before repairing has taken. The use of stress/strain equilibrium curves of the structural adhesives used is made as data base for design purposes.
