What is a flange connection? We can be seen everywhere on industrial sites. After consulting the dictionary, the editor found that, to put it bluntly, in industry, two pipes, fittings, or equipment are first fixed to a flange, which becomes stuck. Then, a pad is added between the two flanges, and bolts are used to fasten them together, completing the connection.

What is a flange plate? Is it important?

Many people are afraid of industrial sites because there are many equipment, and some people have inspected and found that in today's industrial sites, some pipe fittings and equipment used to come with their own flanges. What is a flange? We also refer to it as flange joint.

2. The flange plate is required for rigidity. No matter what kind of pipeline you are, as long as it is a pipeline, you need a connector, which is why flanges are important. For example, in gas or water pipelines, the importance of flanges is second only to the connection of pipelines in pipeline engineering. In the pipeline where the requirements are connected, various devices have a flange plate.

3. What about high-pressure pipelines?

What about high-pressure pipelines? We can use threaded flanges. A threaded flange, also known as a threaded flange, is used for pipe fittings with a diameter less than 100mm.

4. What about pipelines with high pressure?

Assuming a pressure of over 4 kilograms, we need to use welded flanges. Welding flange is a component that connects pipes to each other and connects to the pipe end. There are holes on the welding flange, bolts make the two flanges tightly connected, and a gasket is used to seal between them.

5. Will the flange be corroded and rotted?

Some people are concerned about the effects of corrosion, pitting, rusting, or wear, and flange plates will not have these problems. Many experts claim that flange plates are one of the high-strength materials in construction metal materials. Due to its excellent corrosion resistance, stainless steel can maintain the integrity of engineering design.

6. How to regularly inspect and repair flanges?

The flange is not a preservative and cannot be temporarily stored. It should be understood that it should be checked regularly and repeatedly, just like taking care of fur and leather bags. Daily liquidation and maintenance obligations are necessary. For example, we need to regularly clean the exposed machined surface of the flange and store it neatly in the center of an indoor ventilated area. Stacking or outdoor storage is strictly prohibited. When using flanged valves, especially gate valves, they are only fully open or fully closed in order to prevent erosion of the sealing surface and prevent object wear.
