When installing glass piping, how should the ends be joined if one end is field cut?

When installing glass piping, joining the ends correctly is critical to ensure a proper seal and maintain the integrity of the system. When one end is field cut, it often leaves a plain, unfinished edge. To create a secure joint, it is necessary to combine this plain edge with a bead, which is a rounded, finished edge that is often found on the other segment of the piping.

Joining bead to plain ensures that the bead can effectively mate with the plain end, facilitating a better fit and a tighter connection. The bead helps to create a strong seal, which is essential in preventing leaks and providing structural support. The smooth surface of the bead can also help in distributing the stress and pressure that may occur during operation, making it a more reliable choice compared to other joining methods.

Using a method such as plain to plain would not leverage the additional sealing benefits provided by the bead, potentially leading to a weaker connection. In applications requiring high precision, like those often involving glass piping, this attention to detail in joining methods is crucial for overall performance and safety.
