Flange is a disc-shaped part, which is the most common in pipeline engineering. Flanges are used in pairs and with matching flanges on valves. In pipeline engineering, flanges are mainly used for the connection of pipelines. Install a flange at each end of the pipe to be connected. Threaded flanges can be used for low-pressure pipelines, and welded flanges can be used for pipelines with pressures above 4 kg. Add a gasket between the two flanges and fasten them with bolts. Different pressure flanges have different thicknesses and use different numbers of bolts.
When the water pump and valve are connected to the pipeline, the connection parts of these equipment are also made into the corresponding flange shape, also called flange connection. 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, this type of parts can be called “flange parts”.
The gasket is a ring made of a material that can produce plastic deformation and has a certain strength. Most of the gaskets are cut from non-metallic sheets, or made by professional factories according to the specified size, and their materials are asbestos rubber sheets, asbestos sheets, polyethylene sheets, etc.;
There are also metal clad gaskets made by wrapping non-metallic materials such as asbestos with thin metal plates (white iron, stainless steel);
Threaded flanges are usually used in low-pressure small-diameter pipes, and welded flanges are used in high-pressure and low-pressure large-diameter pipes. The thickness of flanges and the diameter and number of connecting bolts are different for different pressures.
