Certification
All materials are strictly inspected at every stage of the production process from procurement
to product shipment. Visually inspect them for compliance with ASTM, ASME, MSS, DIN,
EN and JIS codes and standards. Support officially certified inspection agencies to witness product
material reporting,
dimensional and quality compliance.
Factory inspections are also supported.Product Description
An Orifice Flange is used in combination with orifice meters to measure the flow rate of oil, gas and other liquids conveyed by the pipeline. Orifice flanges are manufactured to ASME B16.36 in multiple sizes and, material grades.
WHAT IS AN ORIFICE FLANGE?
An orifice flange is used to measure the flow of the fluid conveyed by the pipeline via a flow nozzle positioned on the flange itself. Pairs of pressure tappings are machined onto the orifice flange, making separate tappings on the pipe wall unnecessary.
The traditional orifice flange assembly consists of a pair of flanges, orifice plate, bolts, nuts, gaskets, jacking screws and plugs. Jacking screws ensure the easy removal of the primary flow element.
Working principle of orifice plate flange
The working principle of the orifice plate flange is to achieve flow measurement based on the shape and arrangement of the holes on the orifice plate. When the fluid passes through the orifice plate, the shape and arrangement of the holes will cause the fluid flow to be blocked, thereby forming a pressure difference. The differential pressure sensor is used to measure the size of this pressure difference, and the fluid flow rate is calculated according to the corresponding formula. Orifice plate flanges have the advantages of simple structure, easy use, and high measurement accuracy. They are widely used in industrial fields such as petroleum, chemical industry, thermal power, and water conservancy.
Application of orifice plate flange in industrial production
Orifice plate flanges are widely used in industrial production, mainly including the following aspects:
Flow measurement and metering. Orifice plate flanges can be used for the measurement and metering of liquids, gases, steam and other fluids. They have the advantages of wide measurement range, high accuracy and easy use.
Flow control. The orifice plate flange can control and adjust the flow rate by adjusting the hole shape and arrangement of the orifice plate, so that the flow rate reaches the predetermined target value and meets the production requirements.
Fluid handling and pipeline optimization. Orifice flanges can measure the flow in different pipelines, analyze the distribution and change patterns of fluids, optimize the pipeline structure and fluid treatment system, and improve production efficiency and quality.
To sum up, the orifice plate flange is an important flow measurement device and plays an important role in industrial production and fluid treatment processes.
