Orifice Flanges
Meriam raised face orifice flange unions are designed
to provide a convenient, accurate method for installing
orifice plates. They incorporate accurately positioned
pressure taps for connecting the flow measuring
instruments. This eliminates the requirement of
locating pressure taps in the field. Improper location
of these taps will result in poor accuracy of the flow
measuring system. These built-in taps also reduce field
installation labor necessary for welding, drilling and/
or tapping pressure taps on the flow line itself. Meriam
orifice flanges are provided complete with nuts, bolts,
gaskets and plugs for installation with no other parts
required.
