Abstract

METODO PARA EL TRATAMIENTO TERMICO DE TUBOS METALICOS. COMPRENDE LAS SIGUIENTES FASES: PRIMERA, SE CALIENTA EL TUBO METALICO MIENTRAS SE DEJA AGUA DE REFRIGERACION EN Y JUNTO A UNA PORCION DE DIAMETRO ENSANCHADO, ENTRE UNA SECCION DE TUBO DE PARED DOBLE Y UNA SECCION DE TUBO DE PARED SENCILLA; SEGUNDA, SE PRODUCE EBULLICION NUCLEADA Y EBULLICION DE PELICULA EN DICHA PORCION DE DIAMETRO ENSANCHADO, MEDIANTE LO CUAL SE DESCARGA EL AIRE RETENIDO EN ELLA; TERCERA, SE PRODUCE UNA DIFERENCIA DE TEMPERATURA ENTRE LAS SUPERFICIES DE PARED EXTERIOR E INTERIOR DEL TUBO DE PARED SENCILLA, ADYACENTES A LA PORCION DE DIAMETRO ENSANCHADO, DE MODO QUE SE ORIGINEN UNOS ESFUERZOS TERMICOS SUPERIORES A UN LIMITE DE ELASTICIDAD; CUARTA, A CONTINUACION SE CALDEA DURANTE UN CORTO PERIODO DE TIEMPO; Y POR ULTIMO, SE INTERRUMPE EL CALDEO DE LA SECCION DE TUBO DE PARED SENCILLA, DESPUES DE UN INTERVALO DE TIEMPO PREDETRMINADO.
