Raised face gasket dimension
Raised face gasket dimension
(OP)
All,
My concern is about the width (OD-ID) of raised face gaskets that will be installed for ASME B16.5 flanges, for each Class of the B16.5 flanges the width of gasket (OD)for the same flange diameter is different (Starting from 6" flange diameter),I think that this width of gasket shall cover the raised face section of the flange, In my project we have flanges with different classes 150,300,600 for the same diameter but they have the same raised face section width, So why the gaskets width is different if the rased face setion has the same width? is it related only to pressure rate ?

what you are talking about is for flat face gaskets not raised face,the bolts should not go through the raised face gasket, I mean there are no holes in the raised face gasket, it is flat with no holes.

What I understand from you is that this extra width of the gasket comparing to riased face width is to facilitate the installation for horizontal piping application and exactly to ensure the centering of the installed gasket, also it's clear now that the difference of width for gaskets having different classes is related to the difference in bolt hole and bolt dimensions. Is that correct ?
