Abstract

Un método para producir un tubo orientado biaxialmente de material termoplástico, en donde un tubo en condición de preforma es extruido de material termoplástico y se somete a un acondicionamiento de temperatura. Se hace uso de un dispositivo de expansión y de un dispositivo de retiro el cual se dispone hacia abajo del dispositivo de expansión. El dispositivo de expansión comprende una parte de expansión no deformable y una parte de entrada ubicada hacia arriba de la parte de expansión y que tiene un miembro de sellado superior. El dispositivo de expansión comprende un primer ducto de descarga de gas que tiene uno o más primeros puertos de entrada en la superficie exterior del dispositivo de expansión, un primer puerto de entrada es abierto o cerrado o parcialmente cerrado dependiendo de si el primer puerto de entrada está o no cubierto y cerrado, o parcialmente cerrado, por el tubo. Un primer volumen de gas está presente entre el dispositivo de expansión y el tubo, el primer volumen de gas está limitado en un extremo superior del mismo por contacto de sello entre el tubo en condición de preforma y el miembro de sellado superior de la parte de salida y en un extremo inferior del mismo por acople de sello entre el tubo y por lo menos una porción inferior de la parte de expansión, por ejemplo, cerca o en la transición a la parte de salida. Un primer flujo de gas se realiza desde una primera fuente de suministro de gas por medio del primer ducto de suministro de gas y el uno o más primeros puertos de salida de gas del mismo en el primer volumen de gas y la presión del gas en el primer volumen de gas es usada para causar una expansión gradual del tubo antes que el tubo entre en contacto con la parte de expansión. El primer flujo de gas se mantiene a una primera tasa de flujo de gas constante independiente de la presión de gas.
