Product Description
Flange (Flange), also known as flange flange disc or flange, is a kind of mechanical engineering design commonly used connectors, widely used in industrial production. The following is a detailed description of the flange:
1. Definition and Function
Definition: Flange is a part that connects between the shaft and the shaft. It is used for the connection between the pipe ends. It is also used for the flange on the import and export of the equipment for the connection between the two equipment, such as the reducer flange.
Function: Flange connection or flange joint refers to the detachable connection which is connected by flange, gasket and bolt as a group of combined sealing structure. It can combine two non-communicating pipes into a whole, fix the pipes or install valves, and connect pipes of different diameters or lengths.
2. classification
Flanges can be divided into many types according to their use, structure and connection methods, including but not limited to the following:
According to the connection mode:
Flange
WELDING FLANGE
Clip flange
According to chemical industry (HG) standards, it is divided into integral flange (IF), threaded flange (Th), plate flat welding flange (PL), neck butt welding flange (WN), neck flat welding flange (SO), socket welding flange (SW), butt welding ring loose sleeve flange (PJ/SE), flat welding ring loose sleeve flange (PJ/RJ), etc.
Other categories: including butt-welding ring plate loose sleeve flange, flanging ring plate loose sleeve flange, flange cover, etc.
3. material
Flanges are made of various materials, including carbon steel, low alloy steel, stainless steel, etc. The choice of specific materials depends on the use environment and requirements. For example, stainless steel flanges are widely used in chemical, food and other industries because of their good corrosion resistance.
4. manufacturing process
The manufacturing process of flanges includes heat treatment, machining, surface treatment, inspection and packaging. Machining is through lathes, milling machines, drilling machines and other machine tools for precise processing of flanges to ensure the dimensional accuracy and surface quality of flanges; surface treatment is through rust prevention, painting and other ways to improve the corrosion resistance and aesthetics of flanges.
5. Application Areas
The application field of flange is very wide, especially in petroleum, chemical, pharmaceutical, light industry, electric power, ship and construction and other important fields. For example, in the petroleum industry, oil pipes, gas pipes, valves, wellheads and other equipment need to use flange connection; in ships and water conservancy projects, flange connection also plays an indispensable role; in the construction site of water pumps, pipelines, air conditioning and other equipment, can also be used in flange connection.
