Flange (Flange) and called the flange and flange. Flange to pipe and pipe interconnected parts, connected to the pipe end. There are holes on the flange, so that the two flange bolts tight. The flange gasket seal. Sub-threaded flange connection (wire connected flange and welding flanges).

A discoid flange parts, in the pipeline engineering are the most common, flange are used in pairs. In the pipeline project, mainly used for pipeline flange connection. The need to connect the pipe, flange mounted with a low pressure pipeline, can use the wire connected flange, the use of more than 4 kilograms of pressure welding flange. Between the two flange and gasket, and then tighten the bolts. Different pressure flange with different thickness and the use of different bolt.

Flange (flange also called the flange and flange. Tube and pipe parts connected to each other. Connected to the pipe end. There are holes on the flange bolts, can wear, the two flange. The flange gasket seal. Flanged fittings (flanged pipe fittings) refers to a flange (flanged or disc) pipe. It can be formed by casting and, may also be threaded or welded. Flange connection (flange, joint) consists of a pair of flanges, a gasket and a plurality 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, so that does not leak tight connection. Some fittings and equipment have built-flange, also belongs to the flange connection. Flange connection is an important connection pipeline construction.

Flange easy to use, able to withstand greater pressure. In the industrial pipeline flange connection, use is very extensive. Within the family, the pipe diameter is small, but is low, can not see the flange connection. If a boiler room or a production site, everywhere is the flange connection of pipes and equipment.

Generally speaking, the flange is the role of the pipe connection is fixed and sealed.
