The flange connection is to fix the two pipes, fittings or equipment, respectively, on a flange plate. Between the two flange plates, flange gaskets are used to fasten the bolts together to complete the connection. Some fittings and fixtures have their own flanges and they also belong to flanges. Flange connection is an important connection method for pipeline construction.
According to the connection method, the flange connection types can be divided into plate flat welding flanges, neck welding flanges, neck welding flanges, socket welding flanges, threaded flanges, flange covers, and neck welding rings. Loose flange, flat welded ring loose flange, ring groove flange and flange cover, large-diameter flat flange, large-diameter high-neck flange, eight-character blind plate, butt-welded ring loose flange and so on.
It is not known to human flanges, but it must have been heard for pipe connectors. The flange is a general title for pipeline connection equipment.
What are the advantages of the use of a flange? After the flange is used, simply speaking, it is more convenient for the latter repair to be repaired by simply opening the flange.
There are also many raw materials for flanges, stainless steel flanges, galvanized flanges, etc. The raw material requirements for the flanges will differ depending on the site used and the environment.
Flange coupling means that two pipes, fittings or equipment are first fixed on a flange, then a flange gasket is added between the two flanges, and the two flanges are tightened by bolts later. A detachable joint that makes it tightly integrated.
This connection is mainly used for the connection of cast iron pipe, lining rubber pipe, non-ferrous metal pipe and flange valve, etc. The connection of process equipment and flange is also selected for flange connection.
