Flange is a mechanical part used to connect pipes, valves, pumps and other equipment.
It usually consists of a pair of flange plates, gaskets and bolt nuts. There are bolt holes on the flange plate. The two flange plates are tightly connected together by bolts. The gasket is placed between the flange plates to play a sealing role.
Main types
1. According to the connection method, it can be divided into threaded flange, welded flange and coupling flange, etc.
• Threaded flanges are connected by threads, which is relatively convenient to install, but can bear relatively small pressure.
• Welded flanges are firmly connected and can withstand greater pressure and temperature changes.
• Clamp flanges are suitable for some temporary connections or occasions that need to be disassembled frequently.
2. According to the material, it can be divided into carbon steel flange, stainless steel flange, alloy steel flange, etc. Flanges of different materials are suitable for different working environments and media.
Functions
1. Connection function: Connect different pipes or equipment together to form a complete system.
2. Sealing function: Through the compression deformation of the gasket, ensure the tightness of the connection part and prevent medium leakage.
3. Easy for maintenance and replacement: When there is a fault in the pipeline or equipment, the flange can be easily disassembled for maintenance or replacement of parts.
Application fields
It is widely used in pipeline systems in industries such as petroleum, chemical, electric power, metallurgy, and shipbuilding.
