What mesh size is appropriate for the filter screen used to filter welding slag?

DN100 carbon steel pipe :) My knowledge is limited, so there are many problems!
I’ve never heard of such a filter; it’s probably used as a pre-processing step before driving to prevent welding slag from entering the pump and other equipment. It depends on the precision of your equipment and pumps. During the pre-driving process treatment, we use a filter screen that is attached directly to the flange; I can’t remember the exact mesh size, but it’s roughly similar to that of window screens. The pump is a twin-screw pump, and it’s quite effective
A Y-type filter was selected to remove impurities such as weld slag
30-mesh; filters of this type are designed primarily for use in the petrochemical industry, and they can be found on the samples from many manufacturing plants
It is best to choose 60-mesh. We have encountered situations where slag passed through several filters and eventually made its way into the control valve; it took several days to figure out the cause of this
It is used for temporary filtration before production; mesh sizes ranging from 10 to 40 are suitable. The larger the pipe diameter, the smaller the mesh size that should be chosen, as a too fine mesh can easily be sucked away.
10-40 is sufficient; too high a value can cause blockages, and it’s quite troublesome to clean them on a Y-type filter!
