"Flange" is a transliteration of Flange, also known as a flange or flange, originally referred to as a protruding edge on a structural or mechanical part that is perpendicular to the axis of the part. People often call it a flange. According to the standard, it is a "flange" and the word "disk" can be removed. A flange is a component that connects a pipe to a pipe, a valve fitting, and the like. Flange threaded connection (wire connection) flange and welded flange and ferrule flange are the important connection methods for pipeline construction.

Flange connection refers to the detachable sealing structure of the sealing structure which is composed of flange, gasket and bolt. It is called flange joint. In the pipeline installation project, it is called flange connection.

Flange connection is to fix two sections of pipe, pipe fittings or pipe fittings to one flange first. The gasket is placed between the sealing faces of the two flanges. There are bolt holes on the flange (different pressures, different diameters) The bolt hole diameter and the number of bolts are different. Insert the bolt into the bolt hole of the flange. After the nut is tightened, the specific pressure on the surface of the gasket reaches a certain value and then deforms, and fills the micro unevenness on the sealing surface. So that the two flanges are tightly connected. Some equipment or piping accessories have their own flanges, called integral flanges, and flanges are also required for piping.

The flange connection is a detachable connection that is easy to use and can withstand large pressures. In industrial piping, flange connections are widely used.
