Abstract

METODO PARA PRODUCIR UN REVESTIMIENTO DE TUBO DEFORMADO, PARTIENDO DE UNA SECCION INICIALMENTE TUBULAR (1) HECHA DE UN MATERIAL TERMOPLASTICO QUE TIENE UNA SECCION TRANSVERSAL ANULAR. DE ACUERDO CON EL METODO, LA SECCION TUBULAR QUE SALE DE UNA ESTACION DE MOLDEO POR EXTRUSION SE MUEVE A LO LARGO DE FORMADORES (3) Y ELEMENTOS DE SOPORTE (16) PARA LA PRODUCCION DE UNA DEFORMACION EN FORMA ESENCIALMENTE DE C. EL INTERIOR DE LAS PAREDES DE LA SECCION INICIAL SE MANTIENE A UNA TEMPERATURA MAYOR QUE EL EXTERIOR DE LAS PAREDES, AL MENOS DURANTE LA DEFORMACION DE LA SECCION INICIAL. LA TEMPERATURA DEL INTERIOR DE LA PARED SE MANTIENE PREFERIBLEMENTE MAS BAJA QUE LA TEMPERATURA DE FUSION CRISTALINA DEL MATERIAL PLASTICO.
