Duplex orifice flanges are easy to install and are available in various sizes, grades and the combination of two orifice flanges are known as orifice flange union. Respective dimensions and specifications are provided which makes it easier to manufacture the services. These high-grade flanges are highly reliable from our inventory, so we offer them in different shapes, sizes, dimensions, standards, grades, etc.
Duplex Flanges: An austenitic-ferritic spotless variation with a higher pressure erosion breaking obstruction in contrast with standard austenitic 304 and 316 impeccable, yet with a lower sturdiness and effect strength. This classification of material incorporates grades 2205, F51, F53, and F60.

What is the main motive of orifice flanges?
The function of the orifice flange is to measure the rate of the flow of the product through the piping system. As Orifice flanges contain a hole drilled through the face of the flange perpendicular to the pipe, they are easy to be familiar. They as well contain an extra set of bolts known as jack screws.
