Application Analysis of Flange in Mechanical Design

Flange is a disc-shaped part, and flanges are used in pairs, which are the most common in pipeline engineering. In pipeline engineering, flanges are mainly used for the connection of pipelines. In the pipelines that need to be connected, various flanges are installed. Wire flanges can be used for low-pressure pipelines, and welded flanges can be used for pressures above 4 kg.

When pumps and valves are connected to pipelines, parts of these equipment are also made into corresponding flange shapes, also known as flange connections. Any connecting parts that are bolted at the periphery of two planes and closed at the same time are generally called "flanges", such as the connection of ventilation ducts, such parts can be called "flange parts". But this connection is only a part of the equipment, such as the connection between the flange and the water pump, it is not easy to call the water pump "flange parts". Smaller ones, such as valves, can be called "flange parts".

In pipeline engineering, flanges are mainly used for the connection of pipelines. In the pipelines that need to be connected, various flanges are installed. Wire flanges can be used for low-pressure pipelines, and welded flanges can be used for pressures above 4 kg. Add a sealing point between the two flanges and fasten them with bolts. Different pressure flanges have different thicknesses and use different bolts.
