Flange connection:
Flange introduction:
Flange (Flange) is also called Flange or Flange. Flanges are parts that connect pipes to pipes and valves, connected to pipe ends, and also used in equipment inlet and outlet flanges, used for the connection between two equipment. There are holes on the flange, the two flanges are connected with bolts, and the flange is sealed with gaskets. Flanges are threaded connection flanges, welded flanges and sleeve flanges. Flange connection or flange joint refers to a detachable connection made of flange, gasket and bolt which are connected to each other as a group of assembled sealing structures.
Features: suitable for large pipe diameter, high sealing requirements of pipe connection, such as vacuum tube, etc. Also suitable for glass, plastic, valve parts and pipe or equipment connection. For the connection of cast iron pipe and lined pipe, flange connection is usually used. For the flange connection of special pipe, there is no standard flange pipe fitting, and the specification and size are determined by the manufacturer.
High strength, good sealing performance.
Larger pipe diameter, higher pressure is suitable for occasions.
Equipment and pipeline can be used, so the application is more common; Processing complex, high cost.
The gasket is placed between the two flange connecting surfaces. After tightening the nut, the specific pressure on the surface of the gasket is deformed after reaching a certain value, and the uneven sealing surface is filled, so that the connection is tight and not leaked.
According to the connected parts can be divided into container flange and pipe flange.
According to the structure, there are integral flanges, looping flanges and threaded flanges.
