Characteristic:
Well Screen.Johnson screen is manufactured with V-shaped profile
wire which is spirally wound around a cage of longitudinal support
rods. Each intersecting point of these wires is fusion welded. The
pitch of winding gives different spacing between two adjacent turns
of wire. This spacing gives passage for water to enter. The entire
process is completed on fully computerized machines.
Advantages:
Not easy to jam
the special V shaped wire, make the hole of screen outside face is
smaller than inside, so the hole is not easy to jam.
Slot even
The CNC machine tools strictly control the gap between the wire, so
that the gap is even.
Strong corrosion resistance
Stainless steel 304 have the high corrosion resistance
Industry:
Johnson Screens specific continuous-slot construction aims to
optimize flow rates, minimize clogging and help develop the
water-bearing geological formations faster. It is best applied in
the following situations:
Geological formations comprised of small, fine particles
Water wells where gravel packs will be installed
Thin aquifers, where maximum open area is required
Large- and small-diameter deep wells
