What type of connection allows for temporary repositioning of piping without disconnecting?

1. Swing connection

2. Fixed connection

3. Permanent connection

4. Flexible connection

The correct answer is: Swing connection

A swing connection is specifically designed for applications that require the ability to reposition piping temporarily without the need to fully disconnect it. This type of connection typically incorporates a hinged mechanism, allowing one part of the piping system to swing or pivot, thereby facilitating maintenance or alterations within the system. The versatility of swing connections is important in various plumbing and industrial applications, as it ensures that system modifications can be made easily without compromising the integrity of the plumbing infrastructure. This is especially useful in situations where space is limited or where frequent access to certain components of the piping system is necessary. In contrast, fixed connections do not permit movement or repositioning without separation. A permanent connection is designed for long-lasting, unchanging configurations, making it unsuitable for applications requiring frequent adjustments. A flexible connection allows for some movement but is not designed solely for temporary repositioning as the swing connection is. It serves different purposes, such as absorbing vibrations or thermal expansion, rather than providing ease of access during maintenance or modifications.
