ASME B16.36 Standard-Orifice Flanges, Welding Neck, Threaded, Slip On

ASME B16.36 standard covers pressure-temperature ratings, materials, dimensions, tolerances, testing,and making of flanges (similar to those covered in ASME B16.5) that have orifice pressure differential connections.Coverage is limited to the following:
(a)welding neck flanges Classes 300, 600, 900, 1500, and 2500.
(b)slip-on and threaded Class 300.
(c)welding neck flanges Class 400 in U.S.Customary units in Mandatory Appendix II.

ASME B16.36 defines the dimensions of the orifice flange assembly, including:

• Flange thickness
• Bolt circle diameter
• Bore sizes
• Tap hole size and locations for pressure measurement

These dimensions are essential for ensuring compatibility with piping systems and orifice plates.

Specifications of 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.
