Abstract

SE FACILITA UN SISTEMA DE AISLAMIENTO PARA TUBERIAS QUE INCLUYE AL MENOS DOS TIPOS DIFERENTES DE AISLAMIENTO PARA TUBERIAS, EN EL CUAL EL AISLAMIENTO DE CADA TUBERIA ES UNA COQUILLA FORMADA POR DOS SECCIONES QUE SE JUNTAN, UNA PRIMERA SECCION (1) Y UNA SEGUNDA SECCION (2); AMBAS SECCIONES TIENEN UNA SUPERFICIE DE UNION (3 Y 4)Y, ADEMAS, CUANDO LAS DOS SECCIONES (1 Y 2) SE JUNTAN CON LA SUPERFICIE DE UNION DE LA PRIMERA SECCION (3) APOYANDOSE EXACTAMENTE EN LA SUPERFICIE DE UNION DE LA SEGUNDA SECCION (4), ENTRE LAS DOS FORMAN UNA ESTRUCTURA TUBULAR QUE TIENE UN AGUJERO (6) QUE ES DEL TAMAÑO ADECUADO PARA RECIBIR UNA TUBERIA. DE LOS TRES TIPOS POSIBLES DE AISLAMIENTO DE TUBERIAS DISPONIBLES: AISLAMIENTO A, AISLAMIENTO B Y AISLAMIENTO C, CADA AISLAMIENTO DE TUBERIA ESTA DESTINADO PARA AISLAR TUBERIAS CON DIFERENTE TEMPERATURA EN SU SUPERFICIE; SIN EMBARGO LOS TRES TIPOS DE AISLAMIENTO A, B Y C TIENEN EL MISMO DIAMETRO EXTERIOR.
