Abstract

METODO DE TRATAMIENTO DE TUBERIAS MEDIANTE CALOR.COMPRENDE: HACER CIRCULAR CONTINUAMENTE UN REFRIGERANTE A LO LARGO DE UNA SUPERFICIE DE PARED DE UN TUBO EN LA QUE EXISTEN FACTORES DE CORROSION, MIENTRAS QUE LA OTRA SUPERFICIE DE PARED DE DICHO TUBO, EN QUE NO EXISTEN FACTORES DE CORROSION, ES CALENTADA, ESTABLECIENDO UNA DIFERENCIA DE TEMPERATURA ENTRE AMBAS SUPERFICIES Y PRODUCIENDO CONSIGUIENTEMENTE ESFUERZOS TERMICOS POR ENCIMA DE UN LIMITE ELASTICO EN DIRECCIONES DIFERENTES EN DICHAS SUPERFICIES; Y DEVOLVER DESPUES DE ELLO DICHO TUBO A TEMPERATURA AMBIENTE, DE MODO QUE SE PRODUZCAN ESFUERZOS DE COMPRESION Y TRACCION RESIDUALES, RESPECTIVAMENTE, EN DICHAS SUPERFICIES.
