What is a flange fitting used for?

24 Jul,2025

1. Basic Concepts

Flange fittings are a type of connecting device used in pipeline systems. Their main function is to connect two or more pipes to form a complete fluid transportation system. This is achieved through the combination of multiple components such as flange plates, bolts, and gaskets to ensure a stable connection of the pipes.

2. Main Functions

1. Connection Function: The primary function of flange fittings is to connect pipes to equipment or other pipes. In pipeline systems, various equipment such as valves and pumps often need to be installed as required, and these devices need to be connected to the pipes through flange fittings.
2. Support Function: Because flange fittings have a large contact area, they can also serve to support the pipes. This support function is especially important in high-pressure, large-diameter pipeline systems.
3. Facilitate Maintenance and Replacement: Due to the special nature of flange connections, maintenance and replacement of pipelines become relatively easy. When a section of pipe or equipment fails, it can be quickly repaired or replaced by loosening the bolts of the flange connection.

3. Application Fields

Flange fittings are widely used in various fields such as petroleum, chemical, electric power, metallurgy, and construction. In the petroleum and chemical industries, various fluid media need to be transported through pipelines, and flange fittings, as key connecting components, ensure the safe and stable operation of the pipeline system. In the construction field, flange fittings are also commonly used in heating and drainage systems.

4. Types and Selection

According to different usage requirements, flange fittings come in various types, such as slip-on flanges, butt-weld flanges, and plate slip-on flanges. When selecting flange fittings, factors such as pipeline pressure, medium, and temperature need to be considered to ensure the chosen flange fittings meet the usage requirements.

5. Summary

Overall, flange fittings play a crucial role in pipeline systems. They not only achieve the connection between pipes and equipment but also provide support and make maintenance and replacement of pipelines convenient. In various fields of application, flange fittings play an irreplaceable role, ensuring the stable and safe transportation of various fluid media.
