Stainless Steel Pipe Flanges
Flange is also called flange or flange. Flanges are parts that connect the pipe to the pipe, connected to the end of the pipe. There are holes in the flange and the bolt fastens the two flanges. The flanges are sealed with gaskets. Flange split thread connection (wire joint) flange and welding flange.
Flange is a kind of disklike part, most commonly used in pipeline engineering, flanges are used in pairs and matching flanges on valves. In pipeline engineering, flange is mainly used for pipe connection. A flange can be installed in all pipes to be connected, low pressure pipe can use wire flange, use welding flange with pressure of 4 kg or more. Seal the flange between the two flanges and bolt it. Flanges with different pressures have different thickness and use different bolts.
Pumps and valves, when connected to pipes, are part of the equipment, also made of corresponding flange shapes, also known as flange connections. The connecting parts which use bolt connection and close simultaneously in two planes are generally called "flanges", such as the connection of ventilation ducts, this kind of parts can be called "flange parts". But this connection is only part of a device, such as flange and pump connection, the pump is not called "flange parts." Relatively small such as valves, can be called "flange parts."
Gasket is a kind of ring which can produce plastic deformation and have a certain strength of material. Most gaskets are cut from non-metallic panels or manufactured by professional factories in accordance with the required size of asbestos rubber sheets, stone sheets, polyethylene panels, etc. A metal wrap gasket made by wrapping nonmetallic materials such as asbestos with thin metal plates (white iron, stainless steel).
There is also a winding gasket made of thin steel strip and asbestos tape. The ordinary rubber gasket is suitable for the situation where the temperature is lower than 120 ℃. Asbestos rubber gasket is suitable for water vapor temperature lower than 450 ℃, oil temperature lower than 350 ℃, pressure lower than 5MPa. For general corrosive medium, acid-resistant cotton board is the most commonly used. Metal gasket of lens or other shape made of copper, aluminum, 10 # steel and stainless steel in high pressure equipment and piping. The contact width between high pressure gasket and sealing surface is very narrow (line contact). Low pressure small diameter wire joint flange, high pressure and low pressure large diameter are used welding flange, different pressure flange thickness and connection bolt diameter and number are different.
