There are many kinds of flanges. Many different looks. How can they be called flanges?
Flange is the abbreviation of flange, usually refers to a similar plate shaped parts of the plate around the opening of several fixed holes used to connect other parts. Flanges are used in pairs. Is widely used in machinery, so it is all sorts of strange things, as long as the call or call the flange flange.The flange is the most common in the pipeline project, in pipeline engineering, mainly used for pipeline flange connection.
My car is now used in flange, excavator, the picture below belongs to the common flange, flange and the round pick threads.
The flange connection (flange, joint) consists of a pair of flanges, a gasket, and a number of bolts and nuts. Gasket on the flange sealing surface between the two, tighten the nut, the gasket on the surface pressure reaches a certain value after the deformation, and fill uneven sealing surface, the tight connection. A flange connection is a detachable connection. The connecting parts can be divided into containers, flanges and tubes; in accordance with the structural type, there are integral flanges, looper flanges and threaded flanges. There is a common integral flange flange and butt welding flange. Less rigid flange, suitable for pressure P is less than or equal to 4MPa occasion; also called high neck flange welding flange, large rigidity, suitable for high temperature pressure. Flange sealing surface of the three types: planar sealing surface for the pressure is not high, medium non-toxic occasions; uneven sealing surface, suitable for higher pressure situations; the sealing surface of the tenon, suitable for flammable and explosive, toxic medium and high pressure situations.
