CWEA Maintenance Technologist 1 (MT1) Practice Test

A pipe union is primarily designed to connect two segments of piping together. This type of fitting allows for easy assembly and disassembly of pipe sections, which is crucial for maintenance and repairs. The union's unique design facilitates pipe connection without requiring extensive effort in terms of alignment or the use of specialized tools, making it a practical choice in various installation scenarios.

In addition to its primary function of connecting pipes, unions also allow for the easy replacement of sections without needing to cut the pipe or dismantle larger portions of the system. This feature is especially beneficial in situations where maintenance access is limited, as it minimizes downtime and effort.

While sealing pipe joints, supporting heavy pipes, and diverting flow are important tasks in plumbing and piping systems, they are not the primary purpose of a pipe union, which is specifically focused on making connections.
