Abstract

A pipe line strainer has a strainer body having an inner body wall surface and defining a flow passageway, and further defining a strainer inlet in communication with the flow passageway and a strainer outlet spaced from the strainer inlet along the flow passageway in a direction for fluid flow, and a strainer basket disposed within the flow passageway between the strainer inlet and the strainer outlet. The strainer basket has a strainer basket wall defining a plurality of through apertures of predetermined cross dimension for flow of fluid from the strainer inlet toward the strainer outlet, the strainer basket wall dividing the flow passageway into a first region of flow upstream of the strainer basket wall and a second region of flow downstream of the strainer basket wall. At least one of the first region of flow and the second region of flow has an unequal distribution of flow due to change in incremental flow cross sectional area in the direction for fluid flow, with the larger cross-sectional area coinciding with an area of higher flow.
