Pipe Flange

The Orifice Flange is used to measure the flow of product through the piping system. When the Orifice Plate is installed there is a restriction of flow creating a differential pressure and this is used to measure the flow rate of liquids, steam or gases. The Orifice Plate is a thin plate with a center bore that is determined by the desired flow rate.

ORIFICE FLANGE MATERIAL GRADE AND FACINGS

Orifice Flange assemblies are available in all ASTM material Grades and fall under ASME B16.36 and are supplied with either a Raised Face or Ring Type Joint facing. They are not made in 150# rated Flanges because these Flanges are not thick enough to allow for the drilling of the pressure taps, but are supplied in the 300#, 600#, 900#, 1500# and 2500# Classes.
