What is a flange

The part where the pipe segment is connected to the valve is the flange; its advantage is that flanges are also used for connecting high-pressure pipes. Have you just joined the chemical industry?

A flange is a pipe fitting used for connecting and sealing pipes and equipment.

Flange is a loanword. A protruding rim, edge, rib, or collar, as on a wheel or a pipe shaft, used to strengthen an object, hold it in place, or attach it to another object

Flange is the transliteration of \"flange\", which refers to a flange, a protruding edge, or a disc with a protruding edge. The pipe flanges used in equipment are a typical example of this structure; similar structures such as the bent edges of angle steel or channel steel can also be called flanges.

The above-mentioned individuals have already described the uses of flanges; you can visit the website http://www.hbxfgj.com/product.htm to take a look, as it might be useful to you.

A flange is a type of pipe fitting used to connect pipes with each other, as well as pipes with valves and equipment. There are various types such as pipe flanges and equipment flanges, and they come in high, medium, and low pressure versions as well as in different materials. The choice should be made in accordance with the relevant flange specifications and standards.

Search on Baidu; the explanation needs to be more detailed

Flanges should belong to pipe and valve fittings; currently, there are national standards, standards set by the Ministry of Machinery, and standards set by the Ministry of Chemical Industry.

A flange is a disc-shaped component that is most commonly used in piping systems, and flanges are always used in pairs. In pipeline engineering, flanges are mainly used for connecting pipelines. A flange is installed at each end of the pipe that needs to be connected; threaded flanges can be used for low-pressure pipes, while welded flanges are used for pipes under a pressure of 4 kilograms or more. A seal is added between the two flanges, which are then tightened with bolts. Flanges under different pressures have different thicknesses and use different bolts. When water pumps and valves are connected to pipes, the corresponding parts of these devices are also made in the shape of flanges, a connection method known as flange coupling. Any connecting component that uses bolts to join two planes together at their perimeters and thereby seals them is generally referred to as a \"flange\"; for example, in the connection of ventilation ducts, such components can be called \"flange-type components\". However, such a connection is only a local part of a device; for example, the connection between a flange and a pump doesn’t allow the pump to be called a \"flange-type component\". Smaller items such as valves can be referred to as \"flange components\".

1. Flange connection: The flange connection is an important method for piping construction. Flange connection involves first fixing two pipes, fittings, or components to separate flanges, placing a flange gasket between the two flanges, and then fastening them together with bolts to complete the connection. Some fittings and equipment already come with flanges, and they also utilize flange connections. Flanges are divided into threaded flanges and welded flanges. For low-pressure applications with small diameter threaded flanges, welded flanges are used for high-pressure and low-pressure applications with large diameter flanges. The thickness of the flanges, as well as the diameter and quantity of the connecting bolts, vary depending on the pressure level. Depending on the different pressure levels, flange gaskets are made from various materials, ranging from low-pressure asbestos gaskets and high-pressure asbestos gaskets to metal gaskets. Flange connections are easy to use and can withstand high pressures. Flange connections are widely used in industrial pipelines. Within the household, the pipe diameter is small and the pressure is low; flange connections are not visible. In a boiler room or production facility, there are pipes and equipment connected by flanges everywhere. It is also known as a flange or rim. Parts that connect pipes to each other. Connected to the tube end. The flanges have holes through which bolts can be passed to tightly connect the two flanges. The flanges are sealed with gaskets. Flanged pipe fittings refer to pipe fittings that have flanges (flanges or joints). It can be cast (figure not available), or it can be constructed by threaded connection or welding. A flange joint consists of a pair of flanges, a gasket, and several bolts and nuts. The gasket is placed between the sealing surfaces of the two flanges; once the nuts are tightened, the compressive stress on the surface of the gasket reaches a certain level, causing it to deform and fill in any irregularities on the sealing surfaces, thereby ensuring a tight seal with no leaks. Flange connection is a detachable type of connection. Based on the connected components, they can be divided into vessel flanges and pipe flanges. Classified by structure type, there are integral flanges, slip-on flanges, and threaded flanges. Common integral flanges include flat welding flanges and butt welding flanges. Flat welding flanges have poor rigidity and are suitable for applications with a pressure of p≤4MPa ； Butt weld flanges, also known as high-neck flanges, have high rigidity and are suitable for applications with high pressure and temperature. There are three types of flange sealing surfaces: the flat-type sealing surface, which is suitable for applications with low pressure and non-toxic media ； Roughened sealing surface, suitable for applications with slightly higher pressure ； Tenon-and-socket sealing surface, suitable for flammable, explosive, toxic media and high-pressure applications. A gasket is a ring made of a material that can undergo plastic deformation and possesses certain strength. Most gaskets are cut from non-metallic sheets, or manufactured by specialized factories to specified dimensions; their materials include asbestos rubber sheets, asbestos sheets, polyethylene sheets, etc ； There are also metal gaskets made by wrapping non-metallic materials such as asbestos with thin metal sheets (galvanized steel, stainless steel) ； There is also a type of wound gasket made by winding thin steel strips together with asbestos strips. Ordinary rubber gaskets are suitable for applications with temperatures below 120°C ； Asbestos rubber gaskets are suitable for applications where the temperature of water vapor is below 450°C, the temperature of oils is below 350°C, and the pressure is below 5 MPa. For general corrosive media, acid-resistant asbestos sheets are the most commonly used. In high-pressure equipment and pipelines, lens-shaped or other shaped metal gaskets made of copper, aluminum, grade 10 steel, and stainless steel are used. The contact width between the high-pressure gasket and the sealing surface is very narrow (line contact), and both the sealing surface and the gasket have a high level of surface finish. 2. Flange: Flam, now known as “Phalam”. A city in western Myanmar, the capital of Chin State. To the east it borders the Manipur River, a tributary on the right bank of the Chindun River; to the west it is adjacent to Ram Kalan Mountain. There are roads leading east to Mandalay, north into India to Imphal, and south via the newly built Haka-Gango road to various parts of southern Myanmar.
