A flange is a disc-shaped part, also called a flange or flange. It is a mechanical part that is most common in pipeline engineering.
classification
(1) Divided by material, carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, ppc, etc.
(2) It is divided into push, press, forge, and casting by the production method.
(3) According to the manufacturing standards, it can be divided into national standard, electric standard, water standard, American standard, German standard, etc.
(4) Scope of application: construction, light and heavy industry, plumbing, electricity, etc.
(5) Separate the flange and the welded flange by means of connection. Low-pressure small-diameter wire-bonded flanges, high-pressure and low-pressure large diameters are all welded flanges. The thickness of the flanges of different pressures and the diameter and number of connecting bolts are different.
What is a flange connection?
The flange is the part of the shaft and the shaft that is connected to each other for the connection between the ends of the pipe. It is also used for the flange on the inlet and outlet of the device for the connection between two devices, such as the flange of the reducer. A flange connection or a flange joint refers to a detachable connection in which a flange, a gasket and a bolt are connected to each other as a combined sealing structure. Pipe flange refers to the flange used for piping in the pipeline installation. It is used on the equipment to refer to the inlet and outlet flanges of the equipment. There are holes in the flange, and the bolts make the two flanges tightly connected. The flanges are sealed with gaskets. Flange threaded connection (threaded connection) flange, welded flange and clip flange. Flanges are used in pairs. Low-pressure pipes can be used with wire-bonded flanges, and welded flanges are used for pressures above four kilograms. A gasket is placed between the two flanges and then bolted. Different flange thicknesses for different pressures use different bolts. Pumps and valves, when connected to the pipeline, the parts of these equipment are also made into the corresponding flange shape, also known as flange connection. Connection parts that are bolted at the same time around two planes are generally referred to as “flanges”, such as the connection of ventilation ducts. Such parts may be referred to as “flange parts”. However, this connection is only a part of the equipment, such as the connection between the flange and the water pump, it is not good to call the pump “flange parts”. Smaller such as valves, etc., can be called “flange parts”.
