A Startup Strainer is installed into a pipeline system to remove unwanted debris from the pipeline flow. In contrast to other strainers, Startup Strainers are temporary strainers used in pipelines during system startup. Startup Strainers are not designed to be permanent and should be replaced after system startup is completed. Straining of the pipeline flow is accomplished via a perforated or mesh lined screen.
In general, the size of the screen perforation should be slightly smaller than the smallest debris particle to be removed. If the screen perforation is undersized, the screen may require excessive cleaning. Consequently, if the screen perforation is oversized, unwanted debris may be permitted to flow through the pipeline; possibly damaging downstream equipment.
