Abstract

EN UNA VALVULA, EN PARTICULAR UNA VALVULA DE EXPANSION PARA SISTEMAS DE REFRIGERACION, AL MENOS LA CARCASA (2) Y TODAS LAS PIEZAS (3,4,5) DE CONEXION SON PARTES DE DISEÑO DE GRAN PROFUNDIDAD ELABORADAS DE ACERO INOXIDABLE CON MENOS DE 0,006 % DE C, CON PREFERENCIA MENOS DE 0,05 % DE C. ESTAS PIEZAS ESTAN UNIDAS UNA CON OTRA MEDIANTE SOLDADURA. EL ACERO ES TAN BAJO EN CARBONO QUE A PESAR DEL TRATAMIENTO TERMICO EN LA SOLDADURA ES PRACTICAMENTE INSENSIBLE A CORROSION INTERCRISTALINA. DE AQUI RESULTA UNA VALVULA QUE ES ACEPTABLE DESDE EL PUNTO DE VISTA DEL MEDIO AMBIENTE Y ATRACTIVA DE FORMA VISUAL.
