Strainer/Filter Definition and Purpose

Strainers are used normally for the protection of pipeline and petroleum process equipment installed downstream of the strainer. The equipment protected by our strainers is generally more expensive than the total installation cost of a strainer. Also this equipment is critical to the pipeline or process operation.

Strainers use perforated and/or wire mesh media for straining purposes. These materials are “two dimensional”, meaning they do not have a “Depth” or “Dirt Holding” capacity. This means that when a debris particle is caught in the straining media the opening is blocked or plugged. This results in reduced available opening for flow. Strainer sizing and selection are critical to insure your cleaning cycle time, particle size retention and pressure drop requirements are achieved.
