Orifice Flange

What is an orifice flange?

Orifice flanges are used with orifice meters for the purpose of measuring the flow rate of either liquids or gases in the respective pipeline.There are three types orifice flanges according to their connecting type:welding neck orifice flange,slip on orifice flange and threaded orifice flange.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.

Description

They are similar almost in every aspect to each respective flanges,Cangzhou wilson pipeline  sales@wilsonpipeline.com  the only difference is that orifice flanges have holes in each side of the flange perpendicular to the bolt holes.These holes act as instrumentation outlets for such things as pressure gauges,flow speedometers ect,and that can be threaded or socket in a variety of sizes.Another smaller holes is made among the bolt hole pattern to accommodate a jack screw to assist in separating the flanges after installation or for other inspection services.
