Flanges

What is flange?

Flange, also called flange flange disc or flange. Flange is a part connected between the shaft and the shaft, used for the connection between the pipe ends; It is also useful in the inlet and outlet of the equipment flange, used for the connection between two equipment, such as reducer flange.

What is a flange connection?

Flange connection or flange joint refers to the detachable connection of flange, gasket and bolt connected with each other as a group of integrated sealing structure. Pumps and valves, when connected with pipes, parts of these equipment are also made into corresponding flange shapes, also known as flange connections. In general, the connection parts closed at the same time using bolt connection around the two planes are generally called “flange”, such as the connection of ventilation duct, this kind of parts can be called “flange parts”. But this connection is only a part of the equipment, such as the connection of the flange and the pump, it is not good to call the pump “flange parts”. Relatively small, such as valves, can be called “flange parts.”

Classification of the flange:

According to the connection flange connection types can be divided into: plate flat welding flange, with flat welding neck flange, butt welding neck flange, socket welding flange, threaded flange, flange cover, with neck butt welding ring flange, ring flat welding flange come loose, ring groove surface flange, flange cover, large diameter plate flange, large diameter high blind flange, butt welding neck flange, eight words ring flange, etc.

Application of flanges and Flange joint:

Flanges are used to connect pipes with each other, to valves, to fittings, and to specialty items such as strainers and pressure vessels. A cover plate can be connected to create a “blind flange”. Flanges are joined by bolting, and sealing is often completed with the use of gaskets or other methods.

Flange joint is a kind of component which is widely used in engineering design and involves a wide range of aspects. It is the piping design, pipe fitting valve essential parts, but also equipment, equipment parts (such as manhole, mirror level gauge, etc.) in the necessary component. In addition, other professional such as industrial furnace, thermal engineering, water supply and drainage, heating and ventilation, automatic control,
