Abstract

Un revestimiento (30) de polietileno se jala a través de un dado (36) y a través de un tubo (10) y se deja regresar al diámetro interno del tubo. La fuerza de jalon es la mitad de la resistencia al rendimiento del revestimiento o menos. El dado tiene una entrada, una garganta y una salida, disminuyendo la entrada en diámetro hacia la garganta e incrementándose en diámetro la salida desde la garganta. El revestimiento tiene un diámetro máximo entes del dado, un diámetro mínimo en el dado y un diámetro intermedio después del dado. El revestimiento se dobla hacia adentro antes de entrar en contacto por primera vez con el dado a la entrada, después se dobla en forma continua hasta su diámetro mínimo conforme pasa la garganta y sufriendo se expande resultando en el mencionado diámetro intermedio. La garganta se define por la fusion en una curva continua de un radio que se une a la entrada y un radio que se una a la salida. La entrada es convexa entre donde el revestimiento (30) contacta por primera vez el dado después de doblarse hacia adentro y la mencionada garganta.
