CNC Knowledge: Why is flange called flange?

The reason Flange is called “Flange” is because its name comes from the transliteration of the English word “flange”. It was first proposed by an Englishman named Elchart in 1809, and at the same time the flange casting method was proposed. Although flanges were not widely used in the early 20th century, as the demand for mechanical equipment and pipe fittings increased, flanges began to be widely used in these fields. Additionally, flange is also called flanged convex disc or convex disc. It is a disc-shaped part, usually used in pairs, mainly used between pipes and valves, between pipes and pipes, and between pipes and equipment. The connection plays a sealing role. role. Therefore, the name Flange comes directly from its original English word “flange” and was introduced into Chinese through transliteration.

The main functions of the flange include:

Connection: The primary function of the flange is to serve as a connection for pipes or equipment, holding them tightly together with bolts and nuts.

Sealing: During the connection process, a gasket (such as rubber gasket, metal gasket, etc.) is usually placed between the two flanges to achieve a sealing effect and prevent fluid leakage.

Support: Flanges can also provide some support and fixation for pipes or equipment.

Convenient repair: Since flange fittings are relatively easy to disassemble, this makes maintenance and repair of piping systems more convenient.

Adaptability: Flanges are available in a variety of sizes, pressure levels and materials, which can be selected according to different technical needs.

Flanges can be divided into several types according to their structure and use, such as:

Flat Face Flange

Raised Face Flange

Male and female flanges

Threaded flange

Weld flange

Slip-on strap

etc. Each type of flange has its specific application scenarios and advantages. As an important connection component, flange is widely used in industrial fields.
