Abstract

The subject of this invention is a procedure for repairing piping by means of internal facing which comprises a phase in which a tubular facing body coated, on at least one external surface, with means of adhesion and tightness is inserted into the piping to be repaired. The procedure comprises a second phase in which the tubular facing body is pressurised so that it adheres to the internal surface of the piping to be repaired. Before carrying out the pressurisation of the tubular facing body inside the piping in the procedure according to this invention, a contrasting element is inserted, positioned longitudinally, so as to contrast adhesion of the tubular facing body to the internal surface of the piping in proximity to the contrasting element in such a way as to define evacuation channelling for the air between the tubular facing body and the inner surface of the piping during the subsequent pressurisation phase of the tubular facing body. <IMAGE>
