NRG Global Instruments

“NRG GOBAL INSTRUMENTS” make “ORIFICE FLANGE ASSEMBLIES” are used for measuring flow of various

Liquids, Gases & Steam from 2” to 32” line sizes. It gives an acceptable level of uncertainties

at lowest cost and long life without regular maintenances. Orifice Plates are most commonly

used as primary element for flow measurement in pipelines based upon the principle of

measurement of ‘Differential Pressure’ created when an obstruction is placed in the fluid

flow, due to increase in fluid velocity. The orifice plate dimension is based on BS/ISO- 5167specification.

 

OPERATING PRINCIPAL

When fluids/gas is flowing from main pipeline. Orifice plate restricts the flow and develops the

Differential Pressure which is proportional to the square root of the flow rate.

 

DESIGN

The traditional orifice flange assembly consists of a pair of flanges, orifice plate, bolts, nuts,

gaskets, jacking screws and plugs, (where requested). The flanges are generally weld neck

design, but other options are available, such as Slip-on and threaded.

 

Weld neck Orifice Flange Assemblies:

Weld neck orifice flanges are butt-welded into the pipeline. The inside diameter (or the

schedule) of the pipe should be specified when ordering. Weld neck orifice flanges are

available in classes 150,300 & 600. Raised face (RF) and ring type joint (RTJ) versions can be

supplied.

 

 

 

 

 

 

 

ORIFICE PLATE FLANGE ASSEMBLY COMPONENT:

The orifice – flange assembly consists of a mainline Orifice plate, a set of Orifice Flanges.

This plate is sandwiched between two Orifice Flanges. Tag Plate of orifice plate projects out

from Orifice flanges and it indicates the existence of Orifice plate. Details such as Tag NO

/Orifice ID / Pipe ID / Plate Material are stamped on one side of the tag plate which faces

upstream side of the pipe line.
