What are flange joints known for in water distribution systems?

Flange joints are known for their ability to provide a rigid connection between pipes, which is why they are often regarded as inflexible. This characteristic is particularly important in water distribution systems, where creating a secure and tight seal is essential to prevent leaks and maintain system integrity under various pressure conditions.

The rigidity of flange joints allows them to support high-pressure applications, ensuring that the joints do not flex or bend under strain, which could lead to failures or leaks. In contrast, flexible joints are designed to accommodate movements or adjustments in the piping system that can occur due to thermal expansion or ground movement. Therefore, the inelastic nature of flange joints makes them a reliable choice in applications requiring strong, permanent connections.

Other options, such as high flexibility, simple installation, and low cost, do not accurately represent the primary attributes of flange joints. While they may facilitate robust connections, the installation process can be more complex compared to other joint types, and flange joints tend to be more expensive due to the materials and components involved. Understanding the reasons why flanged connections are typically seen as inflexible helps to appreciate their role in ensuring the reliability of water distribution systems.
