ASTM A182 F51 F53 F55 Duplex Stainless Steel Flange Weld Neck Pipe Flanges ASME B16.36

 

1.ASME/ANSI B16.36 Orifice Flanges have orifice pressure differential connections. Federal can custom engineer your Orifice Flange in a range hole configurations—and any hole, bolt or circle diameter. And when you choose Federal, you’ll know your product will be a quality piece of work, exactly to your specification—and delivered ASAP.

 

These flanges and associated components are often used in conjunction with equipment that helps meter or measure the flow of liquids or gases in a pipeline. Federal can construct Orifice Flanges from any number of construction materials including stainless steel, alloy, carbon steel or any other suitable material of choice.

 

2. Check out available dimensions, grades, tolerances and other specs for the following Federal products:

.Welding Neck Flanges

.Threaded Orifice Flanges

.Slip-On Flanges

 

3. FLANGE - ORIFICE, WELD NECK, ANSI CLASS 300, B16.36 (IN)

Dimensions to ASME B16.36 - Orifice Flanges

Bolt circle diameters are 1/8 inch larger than bolt diameter.

All dimensions except "Thickness of Flange C sizes 1" are the same as a Weld Neck.

Approximate weight is based on a orifice flange union which is a set of flanges, plate not included.
