Abstract
SE DESCRIBE UN METODO PARA MEJORAR LOS ESFUERZOS DE TENSION EN TUBOS DE MATERIALES METALICOS, COMO ACEROS INOXIDABLES AUSTENITICOS, MUY UTILIZADOS EN INSTALACIONES NUCLEARES Y PLANTAS QUIMICAS. ESTE METODO PERFECCIONA, PRINCIPALMENTE POR CONDUCTOS DE DISEÑO COMPLICADO, EL DE MEJORA POR ESFUERZO RESIDUAL, YA QUE ELIMINA LAS POSIBLES BOLSAS DE AIRE QUE PUEDAN QUEDAR EN EL CONDUCTO. EL TUBO SE CALIENTA HASTA LLEVAR LA TEMPERATURA DE LA PARED O A UN ESTADO ESTACIONARIO EN UN TIEMPO DEFINIDO POR UNA ECUACION QUE TIENE EN CUENTA EL ESPESOR MAXIMO DE LA PARED; SE PRODUCE EBULLICION NUCLEADA Y EBULLICION DE PELICULA DE FORMA QUE SI DESCARGA EL AIRE APRISIONADO EN LA TUBERIA, EL TIEMPO DEL TRATAMIENTO TERMICO VIENE DADO POR OTRA ECUACION EN LA QUE SE INCLUYE EL ESPESOR DE LA PARED DEL TUBO. FINALMENTE EL TUBO SE ENFRIA A VELOCIDAD UNIFORME DURANTE UN PERIODO DE TIEMPO DEFINIDO POR UNA NUEVA ECUACION.
