What is Flange?

What is Flange?

Flange, also known as flange flange or flange. A flange is a component that connects shafts and is used for connecting pipe ends; Also useful is a flange on the inlet and outlet of the equipment, used for connecting between two devices, such as a gearbox flange. There are holes on the flange, and bolts make the two flanges tightly connected. Seal the flanges with gaskets. The flange is divided into threaded connection (threaded connection) flange, welding flange, and clamp flange. Flanges are used in pairs, and threaded flanges can be used for low-pressure pipelines. Welding flanges can be used for pressures of over four kilograms. Add a sealing gasket between the two flange plates and tighten them with bolts. The thickness of flanges under different pressures varies, and the bolts used are also different. Any connecting part that is closed and bolted around two planes is generally referred to as a "flange", such as the connection of a ventilation duct. This type of part can be referred to as a "flange type part".

Standard system

There are two main international pipe flange standards, namely the European pipe flange system represented by German DIN (including the former Soviet Union) and the American pipe flange system represented by American ANSI pipe flanges. In addition, there are also Japanese JIS pipe flanges, which are generally only used for public works in petrochemical plants and have a relatively small international impact. The following is a brief introduction to pipe flanges in various countries:
1. European system pipe flanges represented by Germany and the former Soviet Union
2. American system pipe flange standards, represented by ANSI B16.5 and ANSI B 16.47
3. British and French pipe flange standards, each with two casing flange standards.
In summary, the internationally recognized pipe flange standards can be summarized as two different and non interchangeable pipe flange systems: one is the European pipe flange system represented by Germany; The other is the American pipe flange system represented by the United States.
IOS7005-1 is a standard issued by the International Organization for Standardization in 1992, which is actually a pipe flange standard that combines two sets of pipe flanges from the United States and Germany.
