Abstract

Tubo metálico con pernos, perfeccionado, con su correspondiente método de fabricación particularmente adecuado para la realización de cambios de calor para las instalaciones de calentamiento o de refrigeración, provisto, sobre su superficie externa, de una serie de pernos radiales, de sección transversal elíptica, dispuestos en filas situadas a intervalos iguales sobre toda la altura de la superficie del tubo, caracterizado por el hecho de que los ejes mayores de las secciones transversales de los pernos dispuestos sobre cada una de las filas, son paralelos entre sí, estando orientados paralelamente, o con una inclinación de 90º o de 45º respecto del eje del tubo y que cada uno de los pernos de una fila está desviado respecto de los correspondientes pernos de las filas contiguas.
