Orifis flanges are used in combination with air meters to measure the flow rate of oil, gas and other liquids transported by the pipeline. Transparent flanges are produced in ASME B16.36 in different sizes and quantities of materials. An orifice flange is used to measure the flow of fluid transferred by the pipe through the flow nozzle located in the flange itself. The pressure-coupling pair is machined on the diaphragm flange, and the detachment tube wall becomes unnecessary. The Orifice flange is a disc-shaped flange, made with either a raised face or a ring-type ring.
The traditional narrow flange assembly consists of a pair of flanges, aperture plate, bolts, nuts, washers, jack bolts and plugs. Jack screws ensure easy removal of the mains element.What is Oriflate Plate? Transparent flanges in all forged grades of ASTM (ASTM A105, ASTM A350, ASTM A694, ASTM 182 for carbon, alloy and stainless steel flanges, respectively), dimensions (combination of nominal size and pressure rating) and welding Socket, thread or neck shape (WN is most used).
The purpose of the Orifice flange
- They are widely used with pressure difference flowmeters to measure the flow of liquid or gases in a pipe. 2. The orifice plate, a device that measures the flow of fluid or internal gas, is located between two flanges that are connected to a pipe. The orificeplate contains a small hole. There are two holes in each flange that help measure the pressure in the pipe. 4- A “jack” screw, which is installed between two flanges, can separate the flanges during inspection or replacement.
These orifices are used in the following industries: Heavy and light chemicals Nuclear paper Petrochemical Wastewater treatment Wastewater treatment and distribution Electricity generation and refining Oil processing and gas transmission
