Flanges are referred to as flanges, just a general term, usually refers to a disk-like metal body on the periphery of a few fixed holes for connecting other things. It is widely used in machinery. Because it looks strange, as long as it looks like it is called flannel.
 

Flange use :

Most common in pipeline engineering, flanges are used in pairs. In pipeline engineering, flanges are mainly used for pipeline connection. At the end of the need to connect two pipes, each flange is installed, low pressure pipes can use wire flange, more than 4 kg of pressure using welded flange. Put a gasket between the two flanges and fasten them with bolts.

A threaded flange is a kind of flange. The threaded flange joint structure is an assembly, which is composed of a pair of flanges, a number of bolts, nuts and a gasket.

Flanges are divided into threaded connection (wire connection) flanges and welded flanges and sleeve flanges. Low pressure small diameter wire flange and sleeve flange, high pressure and low pressure large diameter are welded flange, different pressure flange thickness and connection bolt diameter and number are different.
 

 

Flange structure type: flat welding plate, flat welding ring loose sleeve type, roll loose sleeve type, butt welding roll loose sleeve type, butt welding ring loose sleeve type, butt welding type, with neck thread connection type, integral and flange cover.

The sealing surface of the flange is: plane, concave, concave, mortise and groove surface, rubber ring connection surface, lens surface and diaphragm welding surface.
