Description

Flange (Flange), is also called flange disk or flange. 
Flanges are parts connected between shafts for connections between pipe ends; flanges are also used for connections between two devices, such as reducer flanges, at the inlet and outlet of the equipment. 
Flange connection or flange joint refers to the detachable connection between flange, gasket and bolt as a group of combined sealing structure. 
Pipe flanges refer to the flanges used in pipe fittings and used in equipment to refer to the inlet and outlet flanges of the equipment. 
The flange is perforated and the bolts fasten the two flanges. 
The flange is sealed with gaskets. 
Flanges split threaded connection (wire buckle connection) flanges, welding flanges and clamping flanges. 
Flanges are used in pairs, low-pressure pipes can be used with wire flanges, and welding flanges can be used for more than four kilograms of pressure. 
Add gaskets between the two flanges and fasten them with bolts. 
The thickness of flanges under different pressures is different, and the bolts they use are also different. 
Pumps and valves, when connected to pipes, parts of these equipment are also made into corresponding flange shapes, also known as flange connections. 
All the connecting parts that are bolted around the two planes and closed at the same time are generally called "flanges", such as the connection of ventilation ducts, which can be called "flange parts". 
But this kind of connection is only a part of a device, such as the connection between flange and water pump, it is not easy to call the pump "flange parts". 
Smaller, such as valves, can be called "flange parts."
