ORIFICE FLANGE
Orifice plate flange is used with orifice meter for for measuring the flow rate of either liquids or gases in the respective pipeline. Pressure pairs “tapings”, mostly on 2 sides, directly opposite each other, are machined into the orifice flange. This makes unconnected orifice carriers or tapings in the pipe wall unnecessary.
It come with either raise face or RTJ facing, which go through rigorous purpose. And it is similar to weld neck flange and slip on flange with extra machining done on it.
Weldneck orifice flanges is use in low maintenance flow measurement. This measurement device is economical choice for an orifice fitting. It has simple process to remove and conduct plate inspection by spreading the flange with single equipment.
What are the applications of jack screw flange?
The main reason of an orifice flange is to be utilize in flow metering of piping systems
It is used for all intensive purpose, likewise slip on and weld neck flanges with extra machining
It is useful for the industries such as petrochemicals, power generation, sewage treatment, oil production and refining, nuclear, water treatment and distribution
Orifice Flanges Advantages
It is used for measuring fluid flow rate in the pipe.
It eradicate drilling and making bores on the pipes for inserting instrumentation examine.
It is a cost saving device to measure flow rate compare to other expensive methods.
It provide accurate readings of flow rate and very worthy.
Orifice plate flange features
It come with either face or ring type joint facing
It has modification of radial tapped hole in flange ring for meter connection
There are orifice plate carrier in these flange due to the reason of fitting meter connections
Additional bolts available serve as a jack to allow the separation of two flanges to change the orifice plate or for other applicable services like inspection
What is the purpose of jack screw flange?
These are used to measure flow rate of product through the piping system. It is easy to recognize because it has hole drill through flange face which is perpendicular to pipe. It also has additional bolt set which is called as jack screws.
