What is a flange?

Flanges are a common connection and are widely used in pipe systems in industrial fields. It acts as a connection, seal and support to ensure the safe operation of piping systems under a variety of pressure, temperature and media conditions. Flange has the advantages of simple structure, easy installation, reliable sealing, easy disassembly and maintenance, so it has been widely used in various industries.

First of all, the main function of the flange is to connect the pipe. It forms a continuous pipe system by aligning the ends of the two pipes with each other and fixing them, and connecting the two flanges together by means of bolts or welding. This connection makes it possible to transfer fluid or gas between pipes and maintain good circulation. The flange connection can be disassembled for easy maintenance and replacement.

Secondly, the flange also plays a sealing role. In piping systems, different media such as liquids, gases or powders are often handled. In order to avoid problems such as oil, gas or powder leakage, the flange is equipped with a sealing gasket or sealing ring, which can form an effective seal at the joint to prevent media leakage. This sealing method is often used in chemical, petroleum, natural gas and other fields with high sealing requirements, to ensure the normal operation of the pipeline system and environmental safety.

In addition, the flange also has the function of supporting the pipe. In some long distance or high temperature conditions, the pipeline will bear large loads and pressures. As a connector, the flange can share the weight of the pipe and enhance the stability and rigidity of the pipe by tightening the connection bolts. This support function plays an important role in many engineering projects, such as the heating system of a building, the pipeline system of an oil refinery, etc.

In summary, flanges are a connector widely used in the industrial field to connect pipes, seal and support the weight of pipes. Flange has the advantages of simple structure, convenient installation, reliable sealing, easy disassembly and maintenance, and is widely used in petrochemical, electric power, shipbuilding, paper making, construction and other industries. With the development of science and technology and the progress of manufacturing process, different types and specifications of flanges continue to emerge, providing more flexible and efficient and reliable pipe connection solutions for all walks of life.
