STRAINERS
A. Strainer Definition and Purpose Strainers are used normally for the protection of pipeline and petroleum process equipment installed downstream of the strainer. The equipment protectedby 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 wiremesh 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 thestraining 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 retentionand pressure drop requirements are achieved. B. Straining Media Selection for Basket The following is a general guideline of media normally used in various applications: Liquid Turbine Meters GasTurbine Meters and Regulators P.D. Meters Centrifugal Pumps Service: Crude Oil Refined Products Coke Fines Water Natural Gas Compressors 1/8” dia. perforated support with 40 x 40 mesh liner 1/8” dia.perforated support with 80 x 80 mesh liner 1/8” dia. perforated

1/4” dia. perforated 1/8” dia. perforated 3/4” flattened expanded metal 1/8” dia. to 3/8” dia. perforated Varies by manufacturerrecommendations, 1/8” dia. perforated to 50 microns

C. Strainer Design and Selection WeamcoMetric Fabricated Strainers are manufactured in several styles or types to meet various applications. Strainer typeselection should be based upon your requirements. A general guideline as follows: Application Description or Requirement 1. Pumps, Flow Meters, Compressors & Control Valve Protection, Low PressureDrop, High Capacity, ease of maintenance, several optional features. Pump Suction & Gas Regulator Protection, relative clean product, very adaptable to various piping arrangements. Style Vertical...
