An overview of standard flanges

A standard flange is a standard fitting used to connect pipes, valves, equipment, etc. It has two types: fixed and removable, common welding flange, threaded flange, clamping flange, etc.

A standard flange usually consists of two flanges that fit with each other, which are bolted together to form a sealed connection. There are a certain number of screw holes on the flange, which can be matched with the corresponding bolts to ensure the firmness of the connection.

Standard flanges have the following characteristics:

1. Disassembly: Standard flanges can be easily installed and disassembled, making the maintenance and repair of the pipeline system more convenient.

2. Good sealing: the standard flange is tightly combined with the connecting parts through sealing devices such as gaskets and sealing rings to ensure the tightness of the connection.

3. Pressure resistance: Standard flanges are usually able to withstand a certain pressure, so they are suitable for various piping systems.

4. Versatility: The standard flange adopts a unified specification and size standard, so it can be used with various brands and models of pipes, valves, etc.

5. Wide applicability: standard flanges are suitable for a variety of media, including gases, liquids and solids.

The specifications and dimensions of standard flanges usually meet international standards, such as the ANSI standard of the United States, the EN standard of Europe and the GB standard of China, etc., which specify the material, size, number of bolts and aperture of the flange and other parameters to ensure that the flange manufactured by different manufacturers can be used interchangeably.
