The low-pressure pipes can be connected with wire flange. Welding flange is used for the pressure of more than 4kg.Place a gasket between the two flanges and bolt them down.
Flanges of different pressure have different thickness and use different bolts.
Pumps and valves, when connected to the pipe, the parts of these equipment are also made into the corresponding flange shape, also known as the flange connection.
General in two planes at the periphery of the use of bolts and closed connection parts, are generally called "flange", such as the ventilation pipe connection, this kind of parts can be called "flange part".
