Basic Introduction to Flat Flange

Flat flange, also known as flat welding flange or flat flange, is a universal flange used to connect pipelines, valves, fans, pumps, and other equipment. The main function of a flat flange is to connect pipelines, allowing the pipeline system to operate normally and facilitating maintenance and replacement of equipment.

A flat flange is generally composed of two identical flanges and several bolts and nuts, and the connecting surface of the flanges is flat. During installation, it is usually necessary to add a sealing gasket between the two flanges to ensure that there is no water or air leakage at the connection. Flat flanges are suitable for pipeline systems under normal pressure and temperature.

The materials for flat flanges generally include carbon steel, stainless steel, alloy steel, etc. Choose the appropriate material according to different usage requirements. There are also many specifications for flat flanges, including different diameters, thicknesses, bolt hole numbers, etc., which can be selected according to the specific needs of the pipeline system.

Flat flanges are widely used in pipeline systems in industries such as chemical, petroleum, natural gas, power, and metallurgy. It has the advantages of easy installation, good sealing, and low cost, and is one of the commonly used flange forms in pipeline connections.
