The characteristics of flange are introduced

Flange, also called flange or flange plate, is a part that connects the pipe with the pipe and is connected to the end of the pipe. The following are the detailed characteristics of the flange:

First, structural characteristics

Disc structure: Flanges are usually disc or ring shaped mechanical parts with a large contact area to provide stable connection and support.

Connection hole: The flange is provided with holes for threading bolts or nuts. The two flanges are tightly connected by tightening the bolts or nuts.

Sealing surface: the sealing surface of the flange has a variety of forms, such as sudden surface (RF), concave and convex surface (MFM), mortise and groove surface (TG), full plane (FF) and ring connection surface (RJ), etc., to adapt to different sealing requirements and working environment.

Second, functional characteristics

Easy connection: flange connection is an important connection method in pipeline construction, with the characteristics of easy installation, disassembly and maintenance. By tightening the bolt or nut, the pipe can be quickly connected and disconnected.

Good sealing: The flange connection is sealed by sealing gasket or sealing ring, which can ensure that the pipeline system does not leak. The gasket or seal ring is usually made of an elastic material with a certain deformability to adapt to the small deformation and displacement of the piping system.

Strong pressure capacity: flange connection can withstand greater pressure, suitable for high pressure pipeline system. The bearing capacity of the flange is related to its material, thickness and structure, and is usually selected according to the pressure requirements of the piping system.

Wide range of application: flange connection is suitable for various media and temperature conditions of the pipeline system, such as oil, gas, water, steam and so on. At the same time, the flange connection is also suitable for various pipe diameters and wall thicknesses, and has a wide range of applicability.

Third, material and manufacturing characteristics

A variety of materials: flange materials are diverse, including carbon steel, stainless steel, alloy steel and other metal materials, as well as plastic, rubber and other non-metallic materials. Flanges of different materials have different corrosion resistance and high temperature resistance, and are suitable for different working environments.

Various manufacturing processes: the manufacturing process of flange includes casting, forging, welding, etc. Flanges of different manufacturing processes have different properties and uses, and can be selected according to actual needs.

Fourth, other characteristics

Standardization: The manufacturing and connection of flanges follow certain standards and specifications, such as the national standard (GB/T), the Ministry of Machinery standard (JB/T), the American standard (ASME B16.5) and so on. These standards and specifications ensure the interchangeability and versatility of flanges, and facilitate the procurement and use of flanges.

Detachable: The flange connection is a detachable connection that facilitates pipe maintenance and replacement. When the piping system fails or needs repair, the flange can be removed to quickly locate and resolve the problem.

In summary, the flange has the characteristics of compact structure, convenient connection, good sealing, strong pressure bearing capacity, wide application range, diverse materials, diverse manufacturing processes, standardization and disassembly. These characteristics make flanges have wide application value in pipeline system.
