Vortex flowmeter flange clamping type and flange pipe type difference

Project Overview

The main differences between the flange clamping type and the flange pipe type (commonly called flange connection type) of vortex flowmeters are in terms of installation method, pressure resistance, cost and applicable occasions:

Method Blue pipe type flange clamping type

In summary, which type to choose? It mainly depends on the specific needs of the actual application, including factors such as pressure rating, pipe size, budget and whether frequent maintenance is required.

1. Installation method:

2. Flange clamp type: This type of flow meter does not have a flange structure itself, but uses Install the two existing flanges on the pipeline. The specific operation is to first place the flow meter between the two flanges, and then secure the flow meter tightly to the pipeline through bolts and nuts. This method is simpler and less laborious. Too much modification to the pipeline is required.

   • Flange pipe type (flange connection type): This type of flow meter has a flange itself, which is directly connected to the method on the pipeline. The flanges are bolted together which means each flow meter has matching flange parts required for installation.Align the flange of the flow meter with the pipe flange and fix it with bolts, which is suitable for a more fixed installation position.

     

3. Pressure resistance and caliber range:

   • Flange clamping type: Due to its structural characteristics, it usually has lower pressure resistance and smaller caliber range. This is due to the limitations of the clamping type fixation method It has the ability to withstand higher pressure and is not suitable for large diameter pipes.

   • Flange pipe type: has higher pressure resistance and wider diameter range. The flange is directly integrated on the flow meter and connected to the pipe flange, which can withstand higher working pressure and is suitable for high-pressure and large-diameter industrial applications.

4. Cost:

   • Flange clamp type: usually lower cost because it does not require its own flange and is easy to install, saving materials and installation time.

   • Flange. Pipe type: Relatively higher cost because additional flange components are included, and the manufacturing and installation process may be more complex.

     

5. Applicable occasions:

   • Flange clamping type: suitable for occasions that are cost-sensitive, have low pressure requirements, and require frequent maintenance and replacement.

   • Flange pipe type: suitable for high pressure and large loads. Flow, industrial environments with high sealing and stability requirements, and fixed installation locations that rarely require disassembly.
