Dec 06, 2017

Flange also known as flange flange or flange. The flange is a connection between the shaft and the shaft for the connection between the pipe end; also used in the equipment on the import and export of the flange, for the connection between the two devices, such as reducer flange. Flange connection or flange joint, refers to the flange, gasket and bolts connected to each other as a combination of a group of sealed structure of the detachable connection. Pipeline flange refers to the pipe fittings in the pipeline with the flange, used in equipment refers to the equipment import and export flange. There are holes on the flange, the bolts make the two flanges tight. The flange is sealed with a gasket. Flange thread connection (thread connection) flange, welding flange and clip flange.

Flanges are used in pairs, low-pressure pipes can use the wire flange, four kilograms above the pressure of the use of welding flange. Add a gasket between the two flanges and fasten it with bolts. Different pressure flange thickness is different, they use different bolts. Pumps and valves, in connection with the pipeline, these equipment and equipment of the local, also made the corresponding flange shape, also known as the flange connection. Any connection parts that are bolted at the same time in both sides are generally referred to as "flanges", such as ventilation ducts, which can be called "flanged parts". But this connection is only a part of the equipment, such as the connection of the flange and the pump, it is not good to the pump called "flange parts." Relatively small, such as valves, etc., can be called "flange parts".

As an iron plate welding flange, many customers are questioned is the quality of iron plate welding flange is better than forging welding flange. In fact, the quality of iron plate welding flange and forged welding flange quality is the same, but the iron plate welding flange in the end what can not be guaranteed it, that is, iron plate welding flange material is not guaranteed, because In the general process, the density of the welded rails of the iron plate is no problem, but during the production process, the blanks of the welded rails of the iron plate are rarely tested, so that, after being produced, Inspection of iron plate welding flange material can not be guaranteed.
