Flange is a disk-like part, in the pipeline engineering is the most common, flanges are used in pairs.
In piping engineering, flanges are mainly used for connection of steel pipes. In the need to connect the pipeline, a variety of installation flange, low pressure pipe can use wire flange, more than 4 kilograms of pressure on the use of welding flanges. Attach the sealing points between the two flanges and tighten them with bolts.
The different pressure of the carbon steel flange has different thicknesses and uses different bolts. Pumps and valves, in connection with the pipe, the parts of these equipment, also made of the corresponding flange shape, also known as the flange connection.
In all two planes in the vicinity of the use of bolts connected with the closure of the connecting parts, generally known as “flange”, such as the connection of ventilation ducts, this kind of parts can be called “Flange type parts.” But this kind of connection is only a part of the device, such as the flange and water pump connection, it is not good to call the pump “flange type parts.” Compared to small valves such as valve, can be called “Flange type parts.”
In industrial pipelines, flange connections are widely used. In the family, the pipe diameter is small, and is low pressure, flange connection is not visible. If you are in a boiler room or at a production site, there is a flange-connected pipe and equipment.
