Introduction of flange
Flanges are simply called flanges, which is just a general term. Usually it means to open some fixing holes in the periphery of the disc-shaped metal body to connect other objects. This thing is widely used in machinery, so it seems odd that as long as it looks like a flange, it gets its name from the English flangee.

Flange is also called flange or flange. The part that connects the pipe to the pipe is attached to the end of the pipe, there are holes in the flanges, and bolts make the two flanges connect tightly. Flanges are sealed with gaskets, and flanges are disc-shaped parts that are most common in plumbing engineering. Flanges are used in pairs. In pipeline engineering, flanges are mainly used for pipeline connection. At the end of the two pipelines that need to be connected, a flange plate is installed on each pipeline. Wire flanges can be used for low pressure pipelines and welded flanges can be used for pressures above 4 kg. Add a washer between the two flanges, then tighten with bolts.
Flanges with different pressures have different thicknesses and use different bolts.
When the water pump and valve are connected with the pipeline, the parts of these equipment are also made into the corresponding flange shape, also called flange connection.
All connecting parts that are bolted on the periphery of two planes and closed at the same time are often called "flanges", such as the connection of ventilation pipes. Such parts may be referred to as "flange parts".
A threaded flange is a type of flange. The threaded flange connection structure is an assembly which consists of a pair of flanges, several bolts, nuts and washers.
According to different pressure levels, flange gaskets also have different materials, from low pressure asbestos gaskets, high pressure asbestos gaskets to metal gaskets.
1. Divided 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 (oversized)
3. According to the manufacturing standards, it can be divided into national standards (chemical industry standard, petroleum standard, electric power standard, machinery department standard, ship standard), American standard, German standard, Japanese standard, Russian standard, etc.
