Abstract

APARATO DE CALENTAMIENTO PARA ALIVIAR TENSIONES RESIDUALES EN UNA JUNTA SOLDADA. COMPRENDE UNA BOBINA (7) DE CALENTAMIENTO POR INDUCCION QUE COMPRENDE VARIAS SECCIONES DE BOBINA (8, 9, 10, 11), CONECTADAS ELECTRICAMENTE UNA A OTRA A TRAVES DE CONECTADORES (12), LAS CUALES TIENEN UNA FORMA QUE CORRESPONDE A LA JUNTA SOLDADA DEL CONJUNTO DE TUBERIAS PRINCIPAL Y DE RAMIFICACION. DICHAS SECCIONES DE BOBINA ESTAN DISPUESTAS DE TAL MANERA QUE LA CORRIENTE ELECTRICA FLUYE EN LA MISMA DIRECCION EN TODAS ELLAS, ESTANDO ALGUNAS DE DICHAS SECCIONES SELECCIONADAS PARA TENER UNA FORMA QUE SE ACOPLE A LA TOTALIDAD DE LAS TUBERIAS PRINCIPAL Y DE RAMIFICACIONES, INCLUYENDO LA JUNTA SOLDADA ENTRE ELLAS.
