A pipe dismantling joint is a unique type of pipe fitting designed to facilitate the removal and replacement of pipes without the need for extensive disruption to the surrounding infrastructure. It acts as a connection point between two sections of a pipeline while incorporating features that allow for quick disassembly. Typically, these joints allow for axial movement, enabling technicians to withdraw one pipe section from another safely and efficiently.

Other manhole shapes can be found, usually squares or rectangles. For example, in the United Kingdom nearly all manhole covers are square or rectangular and very occasionally triangular, but almost never circular. Nashua, New Hampshire, is unusual for having triangular manhole covers that point in the direction of the underlying flow. In 2011, the city began gradually phasing out the triangles,^[9] which were made by a local foundry, because they were not large enough to meet modern safety standards and a manufacturer for larger triangles could not be found.^[10] Some manhole covers in Hamilton, Bermuda, are triangular, and hinged. Some triangular water-main covers also exist in San Francisco.^[11]

Remember, beneath the surface lies a fascinating world waiting to be explored. So, the next time you see a manhole cover, don’t just walk by — give it a silent nod of gratitude for the vital role it plays in keeping our urban world humming along.
