What is the function of a strainer in a piping system?

A strainer in a piping system serves an essential function by removing debris from fluids, which protects downstream components such as valves, pumps, and other equipment from damage that could be caused by particulates. By filtering out unwanted material, strainers help maintain the efficiency and longevity of the entire system, ensuring that the fluid flow is unobstructed and that the components operate as designed.

This preventive maintenance role is crucial, as the presence of debris can lead to blockages or wear that compromises the integrity and function of piping system elements. Unlike options relating to increasing pressure or functioning as a backup flow path, the primary purpose of a strainer is centered around filtration. Monitoring fluid temperature does not fall within the responsibilities of a strainer, as this task typically involves separate devices designed specifically for temperature measurement.
