Abstract

UN PROCESO PARA PRODUCIR UNA TUBERIA DE DOBLE PARED NO CORROSIVA EN LA QUE SE FORMAN TUBOS DE DOBLE PARED CONTINUA SIN SELLAR NO BRONCEADOS DE UNA CIRCUNFERENCIA DADA, DE UNA PLACA METALICA COMPUESTA DE UN PRIMER METAL NO FERRITICO PROVISTO DE UNA PRIMERA REGION DELINEADA DE METAL NO FERRITICO EXPUESTO Y DE UNA SEGUNDA REGION DE UN SEGUNDO METAL EN RELACION RECUBIERTA, DICHA REGION EXPUESTA PROVISTA DE UNA ANCHURA ESENCIALMENTE IGUAL A LA DE LA CIRCUNFERENCIA DEL TUBO ACABADO. EL PROCESO INCLUYE LOS PASOS DE ELEVAR LA SUPERFICIE DEL ACERO INOXIDABLE A UNA TEMPERATURA DE BRONCEADO MIENTRAS MANTIENE EL MATERIAL EN UNA ATMOSFERA GASEOSA HUMEDA QUE CONSTA ESENCIALMENTE DE UN GAS PORTADOR NO REACTIVO Y DE UN GAS REACTIVO PRESENTE EN CONCENTRACIONES SUFICIENTES PARA ALCANZAR EL FLUJO; MANTIENEN LA TEMPERATURA DE LA SUPERFICIE DEL ACERO DURANTE UN INTERVALO DE TIEMPO SUFICIENTE PARA PERMITIR LA FUSION ENTRE EL METAL SELECCIONADO Y LA SUPERFICIE DE ACERO NO FERRITICO; DESPUES DE QUE SE HAYA ALCANZADO LA FUSION DEL METAL, QUE PERMITA ENFRIARSE AL MATERIAL METALICO FUNDIDO RESULTANTE, EN UNA PRIMERA TEMPERATURA BAJA EN UNA ATMOSFERA NO OXIDANTE CONTROLADA EN UNA PROPORCION QUE RETARDA LA FORMACION DE CRISTALES DE ACERO EN GRANO EN EL METAL; Y DESPUES DE ALCANZAR UN PUNTO DE TRANSFORMACION METALURGICA, ENFRIANDO RAPIDAMENTE EL METAL FUNDIDO EN UNA ATMOSFERA CONTROLADA A UNA TEMPERATURA POR DEBAJO DE LA CUAL EL METAL BRONCEADO NO ES REACTIVO CON EL OXIGENO. ESTE PROCESO PUEDE UTILIZARSE CON EXITO EN LA FABRICACION DE UNA TUBERIA DE DOBLE PARED UNICA, RELATIVAMENTE FLEXIBLE Y ALTAMENTE RESISTENTE A LA CORROSION.
