ABSTRACT:
A strainer is provided for removing debris from the gas flow in a pipeline. The strainer is designed with a view to minimizing the pressure drop across it. More particularly, the strainer comprises a spherical shell having inlet and outlet means which are connectable into the pipeline. A circular, concave, perforated plate is mounted within the shell and extends transversely across the path of the gas flow. The plate functions to retain debris in the flow. The combination of the spherical shell and the concave provides a relatively large "trapping" area having a relatively large number of perforations. As a result, the pressure drop across the plate is small compared to prior art strainers. In addition, the inlet means is tubular and conical in configuration, so that the entering flow assumes a divergent pattern. This arrangement results in a reduced pressure drop at the inlet and across the plate.
