Abstract

DURANTE LA FABRICACION DEL TUBO, MEDIANTE UNA PRENSA DE EXTRUSION CON CABEZA LATERAL, SE HACE CIRCULAR, A GRAN VELOCIDAD Y CON UN GRAN CAUDAL, UN GAS DE ENFRIAMIENTO CERCA DE LA PARED INTERNA DEL TUBO Y SE ENFRIA ESTE GAS MEDIANTE UN REFRIGERANTE QUE CIRCULA EN SENTIDO OPUESTO. A ESTE EFECTO, EL DISPOSITIVO LLEVA UN CUERPO (8) DE DOBLE PARED, QUE SE EXTIENDE AXIALMENTE EN EL INTERIOR DEL TUBO EN FORMACION (7), PARA CREAR UN ESPACIO ANULAR 812) SITUADO ENTRE LA PARED INTERNA DEL TUBO Y LA SUPERFICIE EXTERIOR DEL CUERPO (8) EN EL QUE SE HACE CIRCULAR EL GAS DE ENFRIAMIENTO. SE PREVEN UNOS MEDIOS PARA HACER CIRCULAR UN REFRIGERANTE EN UN CIRCUITO QUE COMPRENDE UN PASO (17) EN EL INTERIOR DEL CUERPO (8) Y UN PASO (16) EN EL INTERIOR DE LA PARED DOBLE DEL CUERPO (8) EN EL QUE EL REFRIGERANTE CIRCULA EN SENTIDO INVERSO RESPECTO AL GAS DE ENFRIAMIENTO. EL CONJUNTO DEL DISPOSITIVO EN EL INTERIOR DEL TUBO EN FORMACION PUEDE DESPLAZARSE SEGUN UN MOVIMIENTO DE VAIVEN.
