ASME B16.36 is a standard published by the American Society of Mechanical Engineers (ASME) that covers flanges for orifice flange assemblies. Orifice flange assemblies are used in piping systems to measure fluid flow rates by means of an orifice plate installed between two flanges.

ASME B16.36 flanges are designed to be used with orifice meters, which are devices used to measure the flow rate of fluids in a pipeline. These flanges are specifically designed to work with orifice plates, which are thin plates with a hole in the center that is installed in the pipeline. As fluid flows through the orifice plate, the pressure differential across the plate is measured to determine the flow rate of the fluid.

The ASME B16.36 standard covers flanges for orifice metering applications in sizes from NPS 1/2 through NPS 24. The flanges are available in three pressure ratings: Class 300, Class 400, and Class 600. The standard also specifies the dimensions, tolerances, materials, marking, and testing requirements for these flanges.

ASME B16.36 flanges are typically made from materials such as carbon steel, stainless steel, or alloy steel. They are available in various types, including weld neck, slip-on, threaded, and lap joint flanges.

Overall, ASME B16.36 flanges are a crucial component in orifice metering applications, and their compliance with the ASME standard ensures their reliability and durability in these critical applications.
