Screwed strainers
Flanged strainers How to use:
Fig 4
For a given flowrate extend a horizontal line until it intersects with the diagonal that represents the strainer size and material. Drop a vertical line from this point until it reaches the pressure drop axis. This figure indicates the pressure drop in bar, e.g. 50 000 kg / h of water passing through a DN100 Fig 34 with standard screen would have a pressure drop of 0.1 bar.
