What type of connection provides a removable joint in plumbing applications?

The correct answer highlights flanged connections as a form of plumbing joint that allows for removal. In plumbing applications, flanged connections consist of two flanges that are bolted together, creating a secure yet detachable joint. This design makes it easy to disassemble components for repair, inspection, or replacement without the need for cutting pipes or extensive disassembly of the plumbing system.

Flanged connections are especially beneficial in situations where regular access to the piping system is necessary, such as in high-pressure applications or where significant maintenance is required. Their ability to maintain integrity under pressure while still providing easy access is a key reason why they are widely utilized in various plumbing and industrial settings.

In contrast, other types of connections, like welded connections, create permanent joints that cannot be easily disassembled without cutting. Screwed connections, while nominally removable, may require threading processes and are subject to wear and tear that can complicate disassembly. Push-fit connections offer a quick-install option but are typically designed for permanent installation rather than ease of disassembly. Flanged connections stand out due to their specific design focused on both secure attachment and easy removal.
