ORIFICE FLANGES
Orifice Flanges Manufacture
What is an Orifice Flange?
An Orifice flange is a disc-shaped flange, engineered with either a Raised Face or a Ring Type Joint facing. The traditional orifice flange assembly consists of a pair of flanges, orifice plate, bolts, nuts, gaskets, jacking screws and plugs. Jacking screws ensure the easy removal of the primary flow element.
How does an orifice flange work?
The function of the orifice flange is to measure the rate of the flow of the commodity through the piping system. Orifice flanges are easy to recognize because they have a hole drilled through the face of the flange perpendicular to the pipe. They also have an additional set of bolts called jack screws.
S Nomi is one of the reliable & prominent manufacture of Orifice Flanges in Kolkata, West Bengal, Bihar, Odisha, and Jharkhand. Orifice Flanges are used as a supernumerary of the typical pipe flanges when a stream nozzle or orifice plate is used.
The prime purpose of an orifice flange is to offer an entrée to a pipeline for the metering of gases or liquids.
Our Orifice Flanges manufacture are 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 pipeline and the whole consultation is mentioned as an orifice flange amalgamation.
ORIFICE FLANGES are widely used in conjunction with orifice meters for measuring the rate of flow of liquids and gases.
They are basically the same as standard welding neck and slip-on flanges except for the provision of radial, tapped holes in the flange ring for meter connections and additional bolts to act as jack screws to facilitate separating the flanges for inspection or replacement of the orifice plate.
In choosing the type of orifice flange, the considerations affecting the choice of welding neck and slip-on standard flanges apply with equal force.
