The 6 5/8" pipe base wire wrapped screen has two sets of openings, the outer continuous slot and the holes drilled in the pipe base.
The open area of the pipe base generally is less than that of the outer screen open area, and the inner pipe has a maximum open area of 10%.
Hydraulic performance of the assembly depends on the open area in the pipe base, which usually is made of steel and has an outer screen made of stainless steel.
