The working principle of fluid seamless pipe

Fluid seamless pipe means is a kind of steel pipe with hollow section and no weld from beginning to end; a large number of steel pipes are used for conveying fluids, such as pipelines for conveying oil, natural gas, gas, water and certain solid materials.

Working principle of fluid seamless pipe:

1) Vortex flowmeter

The vortex flowmeter is to place a bluff vortex generator in the fluid, and the speed of the vortex is proportional to the speed of the fluid, so as to calculate the volume flow. Vortex flowmeters are suitable for measuring liquids, gases or steam. It has no moving parts and no dirt issues. Vortex flowmeters are noisy and require high fluid velocity to create vortices.

2) Thermal mass flow meter

Fluid velocity is measured by measuring an increase in the temperature of the fluid or a decrease in the thermal sensor. Thermal mass flow meters have no moving parts or holes and can accurately measure the flow of gas. Thermal mass flow meters are one of the few technologies that can measure mass flow, and are also one of the few technologies used to measure large-bore gas flow.

3) Coriolis flowmeter

This flowmeter uses vibrating 16mn seamless steel tubes to generate deflections corresponding to mass flow for measurement. Coriolis flowmeters can be used to measure the mass flow of liquids, slurries, gases or steam. High accuracy. However, regular maintenance of the pipe wall is required to prevent corrosion.

4) Electromagnetic flowmeter

Measurement principle: Faraday's law of electromagnetic induction states that a conductor moving in a magnetic field will induce an electric potential. Using the principle of electromagnetic measurement, the fluid is a conductor in motion. The induced potential is proportional to the flow rate and is detected by two measuring electrodes, which are then amplified by the transmitter to calculate the flow rate based on the cross-sectional area of ​​the pipe.
