The symbol represented illustrates which type of joint?

The bell-and-spigot joint is a common type of connection used primarily in piping systems. This type of joint features a bell-shaped section on one pipe end, which acts as a female part, and a spigot end on the other pipe, corresponding to a male part that fits into the bell. This design allows for easy alignment and secure assembly, particularly in systems requiring fluid transport, as it reduces the likelihood of leaks.

Bell-and-spigot joints are favored for their ability to accommodate slight dimensional variations or movements, which can occur due to temperature changes or ground settling. Moreover, when properly installed, these joints can create a watertight seal through gravity, which is beneficial in various applications involving water conveyance.

Understanding the characteristics and functions of the bell-and-spigot joint can help identify it in schematic diagrams or technical drawings, as they often highlight the distinctive shape and assembly arrangement of this joint type.
