Johnson Wire Screen 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.
Johnson Wire Screen 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
Johnson Wire Screen 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
