1.Johnson Water well Screen consist of V-shape profile wire and the longitudinal support rods.
Each intersecting point of these wires is fusion welded of water well screen.
2.So it has sturdy constriction and good mechanical property.
3.the V-shape section plane can avoid blockage and make sure of the unimpeded water. the consecutive
slot have more open area, and water well screen can reduce the speed of the water entering to avoid
the sand entering the screen under the great pressure
4.so it can filter sand better. meanwhile ,the slot can change according to the real condition of the earth.
