What is the primary function of couplings?

The primary function of couplings in water treatment systems is to compensate for alignment changes between pipes or components. As systems operate, variations in temperature, pressure, and other external factors can cause pipes to shift slightly out of alignment. Couplings help to connect these components while allowing for some flexibility and movement, ensuring that the system maintains integrity and prevents leaks or stress that could lead to failure.

In addition to their alignment compensation role, couplings also facilitate easy installation and maintenance, allowing for sections of piping to be easily assembled or disassembled. This flexibility is essential for repairs, upgrades, or in cases where a section of the pipeline needs to be removed or replaced.

While other options like assisting in pumping, regulating flow, or reducing friction are important aspects of a water system, they do not directly align with the primary purpose of couplings, which is primarily about maintaining proper alignment and connection between different piping sections.
