Astm A53 est publié par l'American Society for Testing and Materials (Astm), qui est une spécification standard pour les tuyaux en acier sans soudure et soudés conçus pour une variété d'applications. Ce passage est un aperçu des tuyaux en acier sans soudure Astm A53, lisez la suite pour en savoir plus.
Grades de tuyau d'acier A53:
Les tuyaux d'acier d'Astm A53 viennent dans différentes catégories, avec les plus communs étant:
-Grade A: Ce grade est destiné à un usage général et n'est pas destiné à des applications sous pression ou structurelles. Il est souvent utilisé pour les systèmes de plomberie et de distribution d'air à basse pression.
Grade B: Grade B est la catégorie la plus couramment utilisée et convient à une gamme d'applications, y compris les systèmes à haute pression, l'eau et autres fluides, ainsi que les applications structurelles. Il est plus robuste que le grade A.
Variations permises pour le tuyau d'acier A53:
-Épaisseur de paroi: L'épaisseur minimale de paroi en tout point ne doit pas dépasser 12,5% sous l'épaisseur nominale de paroi spécifiée.
Les poids par pied sont plus ou moins 10%
-Diamètre extérieur: Le diamètre extérieur en tout point ne variera pas de la norme spécifiée Plus que:

Applications de tuyau d'acier a53:
-Transport de fluide: ces tuyaux sont couramment utilisés pour le transport d'eau, de pétrole, de gaz et d'autres fluides dans les systèmes à haute et à basse pression.
-Utilisation structurelle: les tuyaux en acier astm a53 de grade b sont utilisés dans des applications structurelles, telles que la construction de bâtiments, de ponts et d'autres infrastructures.
-Applications mécaniques et de pression: les tuyaux de la catégorie b conviennent aux applications où les propriétés mécaniques et la résistance à la pression sont essentielles.
-Protection incendie: les tuyaux astm a53 sont souvent utilisés pour les systèmes de gicleurs d'incendie.
-Cvc (chauffage, ventilation et climatisation): ils sont utilisés dans les systèmes de cvc pour transporter l'air et d'autres gaz.
