Abstract

Aislamiento perfeccionado para tubos metálicos tendidos en la tierra, que se caracteriza por el hecho de que entre una primera capa protectora contra la corrosión adyacente a la superficie externa del tubo y una segunda capa que sirve para la limitación de impulsión está dispuesta una capa intermedia con un elevado contenido de material de carga o relleno.
