Orifice/Reducing Flange

Designed for flow metering systems. Two of these flanges with bolts and jack screws are called an “orifice flange union” and are used in conjunction with an “orifice plate.” The orifice plate is a separate commodity and is not sold as a part of the flange assembly. Each flange is provided with a pair of pressure taps for measurement of pressure drop in the flow through the orifice plate. The taps are precisely located with respect to the orifice plate. Orifice flanges may be provided in one of three types of flanges: Welding Neck, Slip-On and Threaded.

Tongkang Flange provides Orifice flanges,Reducing flanges in all material grades, specifications and sizes.
