2021-05-20
A flange is also known as a flange plate or chemical flange. It is the part that connects a pipe to another pipe at the end of the pipe, with holes on the flange that allow bolts to tightly connect the two flanges. The flange is sealed with a gasket and is a disc-shaped component commonly found in piping engineering. Flanges are used in pairs; in piping engineering, chemical flanges are mainly used for connecting pipes, with a flange plate installed at the end of each pipe that needs to be connected. Threaded flanges can be used for low-pressure pipes, while welded flanges are suitable for pressures above 4 kg. A gasket is added between the two flanges and then tightened with bolts.

Chemical flanges with different pressures have different thicknesses and use different bolts. When pumps and valves are connected to pipelines, the parts of these devices are also made into corresponding flange shapes, also known as flange connections. All connecting components that are connected by bolts and simultaneously closed at the periphery of two planes are generally referred to as "flanges", such as the connection of ventilation ducts. These parts can be referred to as "flange parts".
Threaded flange is a type of chemical flange. The threaded flange connection structure is a component consisting of a pair of flanges, several bolts, nuts, and gaskets.
According to different pressure levels, flange gaskets also have different materials, ranging from low-pressure asbestos gaskets, high-pressure asbestos gaskets to metal gaskets.
1. Classified by material: carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon immersion, PPR, etc.
2. According to the production method, it can be divided into forged flanges, cast flanges, spliced flanges, cut flanges, and rolled flanges (super large).
3. According to manufacturing standards, it can be divided into national standards (Ministry of Chemical Industry standards, petroleum standards, electric power standards, Ministry of Machinery standards, ship standards), American standards, German standards, Japanese standards, Russian standards, etc.
