What Is ASME B16.36?
ASME B16.36 is often abbreviated and referred to as an ORFF. This threaded orifice flange e for metering the volumetric flow rate of liquids and gasses through a pipe. Two orifice flanges together are known as orifice flange union. Each 150# orifice flange comes with two pipe taps, which are meant for measuring the drop in pressure of the flow through an orifice plate. Typically, orifice plates are not available with the weld neck orifice flange and the size of the plates are based on the requirements of the process or the application for which it has to be used. Two jack screws can be used to spread the orifice flange apart in order to change the rtj orifice plate. These flanges are normally available and produced in our factory in the form of weld neck, slip-on, and threaded flanges. These 600# orifice flange dimensions have a raised face.

Why Are Regular Orifice Flanges Installed In A Pipe?
Carbon steel orifice flange is always installed in a straight run of the pipe. The installation has been fashioned in a straight manner in order to avoid turbulence at the plate. As a rule of thumb, an ansi b16.36 orifice flange dimensions has ten diameters of straight pipe upstream as well as five diameters of pipe downstream. Orifice flanges manufacturers in India note that these alloy grades have important properties such as enhanced resistance to corrosion, higher tensile strength, good weldability as well as good formability.
What Is Use Of Orifice Flange?
For instance, alloy grade 316 Stainless Steel Orifice Flanges, which has superior resistance to alloy grade 304 and is referred to as a marine grade metal because of its enhanced resistance to seawater, brine and marine environments with chlorine ions. Besides alloy grade 316 carbon steel orifice flanges tend to offer higher resistance to pitting as well as crevice corrosion in chloride environments.
