Ma\u00eetriser les dimensions des brides ASME B16.5<\/h2>\n

Un tableau des dimensions des brides garantit un ajustement correct, l'alignement des boulons et l'assise des joints. Une mauvaise lecture des tableaux entra\u00eene des erreurs co\u00fbteuses.<\/p>\n

Erreurs courantes<\/h2>\n
    \n
  1. Confusion entre le NPS et les dimensions r\u00e9elles<\/li>\n
  2. M\u00e9lange des classes de pression (150 ne se boulonne pas \u00e0 300)<\/li>\n
  3. Ignorer le type de parement (RF vs RTJ)<\/li>\n<\/ol>\n
