Astm A53 es publicado por la Sociedad Americana para Pruebas y Materiales (Astm), que es una especificación estándar para tubos de acero sin costura y soldados diseñados para una variedad de aplicaciones. Este pasaje es una descripción general de las tuberías de acero sin costura Astm A53, lea para obtener más información.
Grados de la tubería de acero A53:
Las tuberías de acero Astm A53 vienen en diferentes grados, siendo las más comunes:
-Grado A: Este grado está destinado para uso general y no está destinado a aplicaciones de presión o estructurales. Se utiliza a menudo para fontanería de baja presión y sistemas de distribución de aire.
-Grado B: el grado B es el grado más comúnmente utilizado y es adecuado para una gama de aplicaciones, incluidos sistemas de alta presión, agua y otros fluidos, así como aplicaciones estructurales. Es más robusto que el grado A.
Variaciones permisibles para tubería de acero A53:
-Espesor de pared: el espesor mínimo de pared en cualquier punto no debe ser superior al 12,5% por debajo del espesor nominal de pared especificado.
Los pesos por pie son más o menos 10%
-Diámetro exterior: El diámetro exterior en cualquier punto no varía del estándar especificado más de:
|
Nps |
Sobre |
Bajo |
|
1-1/2 y más pequeño |
+ 1/64” |
1/64” |
|
2 y más grande |
+ 1% |
-El 1% |
Aplicaciones de tubería de acero a53:
-Transporte de fluidos: estas tuberías se usan comúnmente para el transporte de agua, petróleo, gas y otros fluidos en sistemas de alta y baja presión.
-Uso estructural: los tubos de acero astm a53 grado b se utilizan en aplicaciones estructurales, como en la construcción de edificios, puentes y otras infraestructuras.
-Aplicaciones mecánicas y de presión: las tuberías de grado b son adecuadas para aplicaciones donde las propiedades mecánicas y la resistencia a la presión son esenciales.
-Protección contra incendios: las tuberías astm a53 se utilizan a menudo para sistemas de rociadores contra incendios.
HVAC (calefacción, ventilación y aire acondicionado): se utilizan en sistemas de HVAC para transportar aire y otros gases.
