Flange Usage Classification and Rating Choose

Flange (flange), also known as flange or flange. Parts that connect pipe to pipe. Connect to tube end. There are holes in the flange, you can wear bolts, so that the two flanges closely linked. Flange sealed with gasket. Flanged pipe fittings (flanged pipe fittings) refers to the flange (flange or plate) of the pipe. It can be cast (not available), but also by screwing or welding. Flange coupling (flange, joint) by a pair of flanges, a gasket and a number of bolt nut composition. Gasket on the flange between the two flanges, tighten the nut, the gasket surface than the pressure reaches a certain value after deformation, and fill the sealing surface uneven, so that the connection tight leakage. Flange connection is a detachable connection. According to the connected components can be divided into container flange and pipe flange. Divided by the structure type, there is a whole flange, flange and threaded flange flange. Common flange flange welding and flange welding. Welded flat flange less rigid, suitable for pressure p ≤ 4MPa occasions; also known as flange welded flange, more rigid, suitable for high pressure and temperature applications. There are three types of flange sealing surface: flat sealing surface, suitable for low pressure, medium non-toxic occasions; concave and convex sealing surface, suitable for slightly higher pressure occasions; tongue and groove sealing surface, suitable for flammable and explosive , Toxic media and high pressure occasions. Gasket is a ring that produces plastic deformation and has a certain strength of the material. Most of the gaskets are cut from non-metal plates, or made by the professional factory according to the required size. The materials are asbestos rubber plates, asbestos plates, polyethylene plates, etc .; also thin asbestos (white metal, stainless steel) And other non-metallic materials wrapped up made of metal pads; there is a thin strip of steel and asbestos with winding wound gasket. Ordinary rubber gasket for temperatures below 120 ℃ occasions; asbestos rubber gasket for water vapor temperature of less than 450 ℃, the oil temperature is less than 350 ℃, the pressure is less than 5MPa occasions, the general corrosion Medium, the most commonly used acid asbestos board. In high-pressure equipment and piping, the use of copper, aluminum, 10 steel, stainless steel lens or other shapes made of metal gasket. High-pressure gaskets and sealing surface contact width is very narrow (line contact), sealing surface and gasket processing finish higher. Flange sub-threaded connection (silk) flange and welding flange. Low pressure small diameter wire flange, high pressure and low pressure large diameter welding flange are used, the pressure of the flange thickness and connecting bolt diameter and the number is different. Hyupshin Flanges supply all steel flanges forging pipe flanges when you choose and buy flanges contact us, sale@hyupshin.cn.
