¿Se ha preguntado alguna vez cómo se clasifican y dimensionan los tubos de acero? En este artículo exploraremos las dimensiones y especificaciones de los tubos de acero, desde los tamaños más pequeños a los más grandes. Aprenderá cómo se estandarizan estas medidas y qué significan para las distintas aplicaciones. Prepárese para descubrir el fascinante mundo de las dimensiones y especificaciones de los tubos de acero.
Una pulgada se divide en ocho partes iguales: 1/8, 1/4, 3/8, 1/2, 5/8, 3/4, 7/8 de pulgada.
Corresponden a lo que comúnmente se denomina tamaños de tubo de 1/8 a 7/8.
Las dimensiones más pequeñas se representan con 1/16, 1/32, 1/64, siendo la unidad pulgadas. Si el denominador y el numerador pueden reducirse (por ejemplo, cuando el numerador es 2, 4, 8, 16, 32), así debe hacerse.
La representación de una pulgada se marca con dos símbolos primos en la esquina superior derecha, como 1/2″.
Por ejemplo, una tubería de agua DN25 (25 mm e igual por debajo) equivale a una tubería de agua imperial de 1″, que también es la antigua tubería de agua de 8 partes. Una tubería de agua DN15 equivale a una tubería de agua imperial de 1/2″, que también es la antigua tubería de agua de 4 partes. Una tubería de agua DN20 equivale a una tubería de agua imperial de 3/4″, que también es la antigua tubería de agua de 6 partes.
Dimensiones: DN15 (tubo de 4 partes), DN20 (tubo de 6 partes), DN25 (tubo de 1 pulgada), DN32 (tubo de 1 y 2 pulgadas), DN40 (tubo de 1 pulgada y media), DN50 (tubo de 2 pulgadas), DN65 (tubo de 2 pulgadas y media), DN80 (tubo de 3 pulgadas), DN100 (tubo de 4 pulgadas), DN125 (tubo de 5 pulgadas), DN150 (tubo de 6 pulgadas), DN200 (tubo de 8 pulgadas), DN250 (tubo de 10 pulgadas), etc.
Las especificaciones de los tubos de acero tienen normas imperiales e internacionales.
