A flange is a component that connects shafts to each other and is used for connecting pipe ends. Also used for flanges on equipment import and export. Used for connecting two devices, such as gearbox flanges.
Flange connection or flange joint refers to a detachable connection in which a flange, gasket, and bolt are connected to each other as a combined sealing structure. Pipeline flange refers to the flange used for piping in pipeline installations, and when used on equipment, it refers to the inlet and outlet flanges of the equipment.
There are holes on the flange, and bolts tightly connect the two flanges. Seal the flanges with gaskets. Flanges are divided into threaded connections (threaded connections), welded flanges, and clamp flanges.
Flanges are used in pairs, with threaded flanges for low-pressure pipelines and welded flanges for pressures above 9LB. Add a sealing gasket between the two flanges and tighten them with bolts. The thickness of flanges under different pressures varies, and the bolts used are also different.
When connecting water pumps and valves to pipelines, the corresponding flange shapes are also made for the parts of these equipment, also known as flange connections.

The main advantages of flanges include the following aspects:
1) High connection reliability: The flange connection tightly connects two flanges through bolts and is used in conjunction with a sealing gasket to effectively prevent leakage and ensure the sealing and reliability of the connection.
2) Wide applicability: Flanges are widely used in construction, light and heavy industries, plumbing, electricity and other fields, suitable for connecting various pipelines and equipment, and have high universality and flexibility.
3) Material diversity: Flanges can be made of materials such as carbon steel, low-alloy steel, stainless steel, etc., and suitable materials can be selected according to different usage environments and needs to improve their applicability and durability.
4) Standardized production: Flanges are classified and produced according to standards such as HG, SH, JB, and GB, ensuring their quality and interchangeability, and facilitating installation and maintenance.
5) Advantages of special materials: Ceramic flanges have high hardness, wear resistance, high temperature resistance, corrosion resistance, and good insulation properties, making them suitable for extreme working environments and significantly extending the service life of equipment.
