Flanges are the parts that connect pipes and pipes to each other. They are used for connecting pipe ends.
Also used in connection between two equipment, such as reducer flange.
Flanged connection or flanged joint refers to the detachable connection of flanged, gaskets and bolts as a group of combined sealing structures.
Pipe flanges refer to the flanges used in pipe fittings and used in equipment to refer to the inlet and outlet flanges of equipment.
There are holes in the flange, and bolts tie the two flanges together.
The flanges are gasketed.
Flange split-threaded (threaded) connection flange, welded flange and clamped flange.
Flanges are used in pairs, the low pressure pipe can use wire flange, more than four kilograms of pressure used welding flange.
A gasket is placed between the two flanges and bolted.
The flange thickness of different pressure is different, they use different bolts.
Water pumps and valves, when connected to pipes, are part of the equipment, also made into the corresponding flange shape, also known as flange connection.
Around where there are two surfaces using bolt connection closed connection parts at the same time, generally known as the "flange", such as ventilation pipe connections, this kind of parts can be called "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 easy to call the water pump "flange parts".
Smaller ones, such as valves, can be called "flanged parts".

Reducer flange for motor and reducer connection, as well as between reducer and other equipment connection.
