What is the name of one end of a cast iron pipe, which is called a bell?

The end of a cast iron pipe referred to as a "bell" is called a spigot. In piping terminology, the "bell" end of a pipe is designed to connect with the "spigot" end of another pipe. The spigot is the projecting end of the pipe that fits into the bell of another pipe, facilitating a secure and leak-proof connection between the two sections. This design is commonly used in various types of piping systems, including wastewater, stormwater, and drainage applications, to ensure proper alignment and support the weight and flow of materials within the pipes. Understanding the relationship between the bell and spigot is essential for proper installation and maintenance of piping systems in mechanical technology.
