What is a "flange" and an introduction to typical materials

2021年12月31日

Flange means "flange": the protruding edge of a structure or mechanical component whose axis is perpendicular to it, and this term comes from a British dictionary. This article will also introduce what flanges are and materials.


Then someone will ask, what is the flange part? The flange part is connected to each other between the connecting shafts between the shaft and the pipe end; Outlet devices are also used on flanges for connections between two devices, such as gear flanges. In a flange or flange joint, the combination of three interconnected sealing structures is detachably connected through flanges, washers, and bolts. The conduit device is located in the pipe flange device, and the flange is used for the pipeline. The device refers to the outlet flange device of the object. There are flange holes on the flange, and the two flange bolts are adjacent. Seal the gasket between two flanges. Partially screw in the flange (threaded) flange, weld and clamp the flange.


The flanges used in low-pressure pipelines can be connected through metal flanges, and the welding flange pressure used exceeds 4 kg. The flange is usually installed with a gasket between two flanges and then fixed with bolts. Different flange thicknesses use different bolts under different pressures. Pumps, valves, and connecting pipes are also used for flanges, also known as flange connections. The use of closed components connected simultaneously, as long as any two bolts are commonly referred to as "flanges", such as the connection of ventilation pipes, can be referred to as the "flange part" of this type of component. But this is only a part of the connection, such as connecting the flange to the pump, which is called the "flange part". Relatively small components such as valves can be referred to as "flange parts". What is flange material? Usually there are carbon steel, low-temperature carbon steel, nickel steel, as well as chromium, molybdenum steel, Mo, stainless steel, steel, alloy, nickel alloy, chromium nickel iron alloy, etc. The mechanical structure of the edge flange can be connected through bolted flanges (such as pipelines), and if flange bolts can be used to connect the interface cover flange, the edge of the cover is. If there is a boiler room or production site, flange materials can be seen everywhere.
