Dimensiones de tuberías de acero

Dimensiones de referencia del diámetro exterior, espesor de pared y diámetro interior de tuberías de acero.

steelpipesdimensions

Resumen

Las dimensiones de las tuberías de acero están estandarizadas por ASME/ANSI B36.10 (acero forjado soldado y sin costura) y ASME/ANSI B36.19 (acero inoxidable). Independientemente del número de cédula, todas las tuberías de un tamaño nominal dado comparten el mismo diámetro exterior. A medida que aumenta el número de cédula, el espesor de la pared aumenta y el diámetro interno disminuye.

Se utilizan tres designaciones de peso tradicionales:

STD (Estándar) — el espesor de pared base para un tamaño dado.
XS (Extra Fuerte) — pared más pesada, a veces llamada XH (Extra Pesado).
XXS (Doble Extra Fuerte) — la pared más pesada, a veces llamada XXH.

Fórmulas Clave

Área de Sección Transversal

$A = \frac{\pi}{4}\left(D_o^2 - D_i^2\right)$

Diámetro Interior a partir del Espesor de Pared

$D_i = D_o - 2t$

Peso por Unidad de Longitud

$W = \rho_{steel} \cdot A_{metal}$

donde la densidad del acero es aproximadamente 490 lb/ft³ (7850 kg/m³).

Notas de Ingeniería

Tolerancias de fabricación en el diámetro externo son pequeñas pero no cero; los valores listados son nominales según ASME/ANSI B36.10/19.
Tuberías de acero inoxidable (B36.19) usan los mismos diámetros externos que el acero al carbono pero tienen paredes más delgadas para algunos calendarios (por ejemplo, 5S, 10S) que no existen en B36.10.
Calendario 160 y XXS proporcionan paredes significativamente más gruesas para servicio de alta presión. Las paredes XXS son más gruesas que Sch 160 para tamaños de 1/2 in a 6 in.
El peso de la tubería depende de la densidad del material; las tablas asumen acero al carbono a 490 lb/ft³. Ajuste proporcionalmente para otras aleaciones.
El peso del agua asume el diámetro completo y una densidad de 62.4 lb/ft³.
Para equivalentes métricos: 1 in = 25.4 mm; 1 lb/ft = 1.488 kg/m.
