Pipeline strainers are utilized in various industrial applications to provide protection for downstream equipment from contaminants that
may be present in the pipeline. Based on the specific application there are numerous specifications that need to be followed to ensure the
strainers are fabricated to effectively meet the process requirements. Strainers are sometimes compared with filtration but at a coarser
level of separation.
A filter is a medium that is designed to remove particles of a designated micron size while a strainer utilizes a perforated plate or a
mesh screen to remove larger particles from a process stream. Most filters use a disposable medium while strainers are designed to remove
larger visible particles down as low as .001inch in diameter and the strainer can be reused after cleaning.
Strainers may be a simplex design where the flow has to stopped or diverted during cleaning of the screen or they may be a duplex configuration that allows for continuous flow when one strainer is being serviced and the flow switched to the other side. Either way it is very important to ensure the strainer has effective surface area to be practical for the specific application to reduce operational maintenance and cleaning.

Fabricated pipeline strainers are pressure vessels with a removable basket screen or plate internal of a specific size and perforation that collects unwanted materials or sometimes wanted materials that need to be recovered for other processes. In simplistic terms pipeline strainers can be considered a protective mechanism that protects sensitive downstream equipment from damage and premature fouling.

Some examples would be downstream equipment such as meters, pumps, compressors, traps, valves and even filters themselves. Pipeline strainers are used in a variety of industries such as petrochemical, water treatment, petroleum, industrial, etc., and depending on the application the configuration and design may vary from a vertical or horizontal orientation. There are also options for flanged bolted covers or a quick opening style for faster and easier access for maintenance and cleaning of the internal plate or screen.
