Abstract

DOS TUBERIAS DE ACERO EXTERIORES (16 Y 16A) ESTAN CADA UNA CUBIERTAS CON TUBERIAS DE REVESTIMIENTO RESISTENTES A LA CORROSION (18 Y 18A) DE MATERIAL PLASTICO COMPRESIBLE HASTA CERCA DE LOS EXTREMOS (20, 20A) DE LAS TUBERIAS EXTERIORES PARA DEJAR UN ESPACIO ANULAR O ESCARIADO (24 Y 24A) EN CADA UNO DE ESOS EXTREMOS. UN ELEMENTO TUBULAR DE UNION (2) DE MATERIAL DUCTIL RESISTENTE A LA CORROSION Y DEFORMABLE PLASTICAMENTE, POR EJEMPLO, LATON O ACERO INOXIDABLE, POSEE DOS ZONAS EXTREMAS TUBULARES (4 Y 6) QUE SE EXTIENDEN EN DIRECCIONES OPUESTAS A PARTIR DE UNA ZONA TUBULAR INTERMEDIA (8) QUE POSEE UN DIAMETRO EXTERIOR MAYOR QUE EL DE LAS ZONAS EXTREMAS (4 Y 6) Y UN DIAMETRO INTERIOR MAYOR QUE EL DE LAS ZONAS EXTREMAS CITADAS. LAS ZONAS EXTREMAS (4 Y 6) ESTAN RODEADAS POR NERVADURAS (12). INICIALMENTE, EL DIAMETRO EXTERIOR DE LAS ZONAS EXTREMAS (4, 6) ES MENOR QUE EL DIAMETRO INTERIOR DE LAS TUBERIAS REVESTIDAS (18, 18A). ASI, CADA TUBERIA REVESTIDA (16, 16A) PUEDE SER AJUSTADA SOBRE LAS ZONAS EXTREMAS (4 Y 6), CON LA ZONA INTERMEDIA (8) OCUPANDO EL ESPACIO ESCARIADO COMBINADO (24, 24A). UNA HERRAMIENTA APLICADA INTERNAMENTE EXPANDE RADIALMENTE LOS ZONAS EXTREMAS (4 Y 6) PARA COMPRIMIR LAS TUBERIAS DE RECUBRIMIENTO PLASTICAS (18, 18A) CONTRA LAS TUBERIAS EXTERIORES (16, 16A) UNA DISTANCIA EN EL RANGO DEL 8% AL 30% DEL ESPESOR DE PARED DE LAS TUBERIAS DE RECUBRIMIENTO. A CONTINUACION SE SUELDAN JUNTOS LOS EXTREMOS ADYACENTES (20, 20A) DE LAS TUBERIAS EXTERIORES EN 28. LA SUPERFICIE EXTERIOR DE LA ZONA INTERMEDIA (8) PUEDE LLEVAR UN MATERIAL DE AISLAMIENTO TERMICO. EL ELEMENTO DE UNION (2) PRESERVA LA INTEGRIDAD DE LA RESISTENCIA A LA CORROSION INTERNA A TRAVES DE LA UNION ENTRE LAS TUBERIAS EXTERIORES.
