Orifice Flange Definition:
Orifice flange is used to measure the flow rate of the liquids in a piping system,it could be water,gas or other liquids.The orifice flanges are usually used with the orifice plates or meters in the pipe joints.
Form of the Orifice Flange:
There are two tappings are machined into the two orifice flanges, and the position of the two tappings is opposite, commonly the tappings are sealed by a plug or a bolt. When the orifice flange is installed, the two tappings are used to put the flow rate meter. And commonly there are also one or two jack screw is machined on the orifice flanges, it is used to facilitate separating the flanges joint when inspection or replacement, the jack screw could prevent the damaging of flange sealing faces .
Type of Orifice Flanges:
The Orifice flange could be in many different types, welding neck orifice flanges, slip on orifice flanges or threaded orifice flanges. The sealing face of the orifice flange could be Raised Face(RF) or Ring Type Joing (RTJ)
