Stainless Steel Flange 304 Flange Forged Protruded Plate Flange 1.6mpa PN16 (1 Piece) DN100

Flange is a transliteration of Flange, also known as Flange or Flange, which refers to the protruding edge perpendicular to the axis of structural or mechanical parts. People often called flannel, in accordance with the specification of the name, is the "flange", you can remove the "plate" word. Flanges are parts that connect pipes to pipes, valve accessories, etc. Flange threaded connection (wire connection) flange, welding flange and sleeve flange are important connection methods in pipeline construction.

Flange connection refers to the detachable sealing structure composed of flange, gasket and bolt, which is called flange joint. In pipeline installation engineering, it is called flange connection.
Flange connection is to put the two pieces of pipe and pipe fittings or piping accessories, fixed on a flange, a first gasket in between the sealing face of the flange, flange there are bolt holes (different pressure and different size of bolt hole diameter and the number is not the same), insert bolt flange bolt hole, tighten the nuts, gasket on the surface of a pressure deformation after reaching a certain value, And fill the sealing surface of the micro-uneven, so that the two flanges are tightly connected without leakage. Some equipment or pipe accessories have their own flanges, called integral flanges, and pipes also need to use flanges.
Flange connection is a kind of removable connection, easy to use, can withstand large pressure, in the industrial pipeline, flange connection is widely used.
There are four basic types of flange sealing face: plane sealing face flange (including plane, code FF and convex, code RF), suitable for pressure is not high, non-toxic media occasions and nominal pressure is less than 4 OMPa grade; Concave and convex sealing face flange (code FM), suitable for high pressure occasions, can be used for nominal pressure 2.5, 4.0, 6.4MPa grade; Tenon groove sealing flange (code TG), suitable for flammable, explosive, toxic media and high pressure occasions; Ring connection flange (code RJ) is mainly used in high temperature and high pressure conditions.
In the European system flanges and national standard flanges, using PN mark, nominal pressure is PN2.5 ~ PN400, that is, nominal pressure is 2.5 ~ 400bar(bar), i.e. 0.25 ~ 40.OMPa (mpa).
