Flange is abbreviated as flange, which is just a general term. It usually means that several fixing holes are made around the periphery of a disk-like metal body for connecting other things. This thing is widely used mechanically, so it looks strange, as long as it is called a flange, its name is derived from the English language.
Flange is also called flange or flange. The parts connecting the pipe and the pipe are connected to the pipe end. There are holes in the flange, and the bolts tightly connect the two flanges. The flanges are sealed with gaskets. Flange is a disc-shaped part, the most common in pipeline engineering, flanges are used in pairs. In pipeline engineering, flanges are mainly used for connection of pipelines. At the end of the two pipes that need to be connected, install a flange each. Low-pressure pipes can use wire flanges, and welding flanges for pressures above 4 kg. Add a gasket between the two flanges, and then tighten with bolts.
Different pressure flanges have different thicknesses and use different bolts.
When the water pump and valve are connected to the pipeline, some parts of these equipments are also made into corresponding flange shapes, also called flange connection.
Any connecting parts that are bolted on both sides and closed at the same time are generally called "flanges". For example, the connection of ventilation pipes, this type of parts can be called "flange parts".
Threaded flange is a kind of flange. The connection structure of the threaded flange is a combination, which is composed of a pair of flanges, a number of bolts, nuts and a gasket.
