What is a Orifice Flanges?
Orifice flanges are used as a supernumerary of the typical pipe flanges when stream nozzle or orifice plate is used. The prime purpose of an orifice flange is to offer an entree to a pipe line for metering of gases or liquids. These flanges are supplied in the course of suitable test certificates of standard raw materials and finished products. An orifice plate is crammed together in the middle of a team of flanges when it is being connected in a pipe line and the whole consultation is mentioned to as an orifice flange amalgamation. Our orifice flanges can further be customized in terms of thicknesses, sizes and specifications as per the specific requirements of our clients.
Orifice flanges used?
When two orifice flanges are used together it is described in the industry as an orifice flange union. Each individual orifice flange comes with two pipe taps which are used for measuring the pressure drop of the flow through the orifice plate. Orifice plates donâ€™t actually come with flanges and they are sized depending on the process requirements. It is necessary to use two jack screws to spread the flanges apart so that the orifice plate can be changed.
An Orifice plate is a thin plate with a hole in the middle and it is placed in a pipe in which liquid flows. When the fluid reaches the orifice plate, the fluid goes through the small hole and the velocity and the pressure of the liquid changes. The liquid expands and the velocity and pressure changes again. If you measure the difference in liquid pressure between the normal pipe section and where it flows through the plate, the cliometric and mass flow rates can be calculated.Orifice flanges tend to be installed in a straight run of pipe so that turbulence can be avoided at the plate.
When you are installing the orifice plate flange the pressure taps need to be at the same height to each other. When making the calculation for the orifice plate, the static head of the tubes should be the same on both sides of the orifice plate. It is advised that pressure taps should not be installed facing down because the taps could potentially become plugged with debris in the line.

Benefit of Orifice Flanges
- Measures the fluid flow rate in the pipe.
- Gives highly accurate flow rate readings and is extremely reliable.
- Gives you a cost effective ways of measuring flow rate compared to other methods.
- There is no need to drill and make bores on pipes for inserting instrumentation probes.
Application of Orifice Flanges
- Orifices are relatively inexpensive
- Orifice offers very less drop of pressure
- Orifices are suitable for most of liquids and gases
- Design and construction of orifice will be very simple
- Orifices are small plates and easy to install and uninstall
- Orifices are capable to determine a wide range of flow rates
- Orifices are capable to determine a wide range of flow rates
- Maintenance of orifice is quite easy and hence they are easy to maintain
- Change of price of orifice will not be changed dramatically with change in size of orifice
