100 es el schedule. En la tabla de schedules se indica el diámetro interior en pulgadas. 100 no son cien pulgadas. No tengo a la mano la tabla de schedules de bore diameters, pero si la consigo se la envío. Por eso indiqué quen USA los diámetros interiores se indican en pulgadas.

Aquí está la referencia de schedules. Es para tuberías pero es igual que para bridas. Puede ser (por ejemplo) schedule 40 o 80, y lo que cambia generalmente es el espesor de la pared (wall thickness), el bore (diametro interno) permanece igual.

neutral  xxxmediamatrix: I would like to agree (and I will, if/when I'm convinced) - but first, can you suggest a context where a flange might be 100 inches (!) larger than some other component?
13 mins

agree  Daniel Grau: Sí, es "nominal bore", pero expresado en milímetros (25 veces más pequeño).
1 hr
  -> Gracias Daniel. Por eso puse pulgadas (USA)

neutral  Walter Blass: Según ANSI B 36.10, por cada dámetro nominal (genéricamente: Nominal Pipe Size= NB), el diámetro exterior es constante. A mayor schedule, corresponde mayor espesor de pared y menor diámetro interior. Check the standards: Sizes, OD's & wallthicknesses

  -> NB: is nominal bore (internal diameter)

nb
Diámetro nominal


Explanation:
Que es la designación en español. Es un valor genérico que define valores de diámetro normalizados. En el caso de tuberías, se definen diámetros exteriores constantes, a los que corresponden interiores variables según espesor de pared (según rango de presiones admisibles).

http://en.wikipedia.org/wiki/Pipe_(material)
• There are two common methods for designating pipe outside diameter (OD). The North American method is called NPS ("Nominal Pipe Size") and is based on inches (also frequently referred to as NB ("Nominal Bore")). The European version is called DN ("Diametre Nominal" / "Nominal Diameter") and is based on millimetres. Designating the outside diameter allows pipes of the same size to be fit together no matter what the wall thickness.
