What is a flange? What is the function of a flange?

A flange is also called a flange plate or a rim. It is a part used to connect pipes to each other, attached to the pipe ends. The flange has holes, and bolts fasten the two flanges tightly. A gasket is used for sealing between the flanges. A flange is a disc-shaped part, most commonly used in pipeline engineering, and flanges are always used in pairs. So what is a flange plate? What is the function of a flange plate?

I. What is a Flange Plate?

A flange plate, referred to as a flange for short, is a general term. It usually refers to a disc-shaped metal body with several fixing holes around it for connecting other components.

II. What are the Functions of a Flange Plate?

1. Flange plate connection is easy to use and can withstand high pressure.

2. The main function of a flange plate is sealing, which requires no additional parts. There are many holes around the flange plate for connecting with other flanges—some are directly welded to pipes. Most commonly used flange plates have holes around them for easy assembly and reusability, making maintenance convenient.

3. Flange plates can be installed on the external threads of pipe ends to seal the pipeline as plugs. They have dustproof, waterproof, and corrosion-resistant properties.

4. In industrial pipelines, flange connections are widely used. In households, pipelines are small in diameter and low in pressure, so flange connections are not visible. However, in boiler rooms or production sites, flange-connected pipelines and equipment are everywhere.

5. Flange covers are mainly used for equipment testing, pressure testing, etc.
