Application practice of octagonal ring orifice plate in orifice plate flowmeter

　　With the continuous progress of technology, the types of orifice plate flowmeter is also increasingly rich, in which the octagonal ring orifice plate as a special type of orifice plate, because of its unique structure and superior performance, in Shanghai Dazhuan and other enterprises in the application of the practice shows a significant advantage.

　　The basic principle of the orifice plate flowmeter is to install an orifice plate in the pipeline, so that the fluid flows through the orifice plate to produce a pressure difference, so as to calculate the flow rate. Octagonal ring orifice plate as a kind of orifice plate flowmeter, its structure is characterised by the shape of the orifice plate for the octagonal ring, this design not only increases the strength of the orifice plate, but also improves the accuracy and stability of the measurement. When the fluid flows through the octagonal ring orifice plate, it will form a high-pressure area in the upstream of the orifice plate, and a low-pressure area in the downstream, according to the law of hydrostatics, the pressure in the high-pressure area is greater than the pressure in the low-pressure area, so a certain pressure difference will be formed. Orifice plate flowmeter through the measurement of this pressure difference, combined with the density of the fluid, viscosity and other parameters, the use of specific formulas, you can derive the flow rate of the fluid.

　　In the petrochemical industry, octagonal ring orifice plates are widely used for flow measurement of various liquids and gases. For example, in an oil refinery, octagonal ring orifice plates are used to measure the flow of crude oil. By analysing the measured data, the refinery optimised the production process and improved product quality and yield. In addition, octagonal ring orifice plates are also used to measure the flow of gases such as natural gas, providing reliable data to support production in the petrochemical industry.

　　Power Industry Applications

　　Octagonal ring orifice plates are also widely used in the power industry. For example, in thermal power plants, octagonal ring orifice plates are used to measure the flow of steam. By monitoring and controlling the steam flow in real time, the thermal power plant achieves precise control of the steam flow and improves energy efficiency. In addition, the octagonal ring orifice plate is also used to measure the flow of water and other media, providing a strong guarantee for the production of the power industry.

　　Metallurgical Industry

　　In the metallurgical industry, the octagonal ring orifice plate also plays an important role. For example, in steel mills, octagonal ring plates are used to measure the flow of gas. By monitoring and analysing the gas flow in real time, the plant optimises the combustion process and reduces energy consumption and environmental pollution. In addition, the octagonal ring orifice plate is also used to measure the flow of oxygen, nitrogen and other gases, providing reliable data support for the production of the metallurgical industry.

　　Other Industry Applications

　　In addition to petrochemical, electric power and metallurgical industries, octagonal ring orifice plates are also widely used in other industries. For example, in the gas transmission pipeline, the octagonal ring orifice plate is used to measure the flow size and pressure change of gas. In industrial combustion furnaces, the Octagonal Orifice Plate is used to measure gas flow and pressure variations and to optimise the combustion effect by controlling the gas flow. In addition, the octagonal ring orifice plate is also used to measure the flow of various liquids and gases, providing reliable data support for the production of various industries.

　　In summary, Shanghai Dazhuan orifice plate flowmeter in the octagonal ring orifice plate application practice shows that in the petrochemical, electric power, metallurgy and other industries have been widely used and achieved remarkable results. It is believed that with the continuous progress of technology and application practice in-depth development, octagonal ring orifice plate will play an important role in more fields and provide more reliable data support for the production of various industries.
