Abstract

Un procedimiento para producir un tubo de plástico que tiene forma ovalada en sección transversal de una gran precisión dimensional, que comprende conducir un tubo de plástico aproximadamente conformado que tiene una sección transversal ovalada, el cual está en estado ablandado y constituido por una parte de diámetro grande, una parte de diámetro pequeño y partes o zonas de transición que las conectan entre sí, a un depósito de refrigeración mientras se ajusta su forma haciéndolo pasar a través de un tubo de conformación con su parte de diámetro grande hacia abajo; enfriar el tubo de plástico de forma ajustada en el depósito de refrigeración sumergiendo la parte de diámetro grande, o bien la parte de diámetro grande y una parte de las zonas de transición contiguas a ella, en un baño refrigerante; y someter la parte del tubo de plástico de forma ajustada que está fuera del baño refrigerante a una ducha de un líquido refrigerante.
