Johnson screen:
The Johnson Screen consist of V-shape profile wire and the longitudinal support rods. Each intersecting point of these wires is fusion welded. So Johnson screen pipe has sturdy constriction and good mechanical property. The V-shape section plane can avoid blockage, and make sure of the unimpeded water. The continuous slot have more open area, and it can reduce the speed of the water entering to avoid the sand entering the screen under the great pressure, so water well screen pipe can filter sand better. Meanwhile ,the slot size can be changed according to the real condition of the earth.

Johnson Screen Vee-Wire Profile wires range in width from 0.020 inch (0.508mm) to 0.195 inch (4.953mm) and in height range from 0.040 inch (1.016mm) to 0.363 inch(9.220mm) , Other wire shapes is also available:

Advantages:
1.Screens with high open area are more suitable for the construction of high quality water wells ,oil wells ,and gas wells.
2.Low cost operation screens with high open area shall favor groundwater infiltration.Abundant water shall reduce the water level’s down,thus to save energy consumption.
3.Reduce the abrasion of the pump
Under the same condition ,high open area can make the speed of ground water’s entering into the screen much slower than any other filtration apparatus,which will avoid sand’ entering into the screen because of high pressure ,thus reduce the abrasion of the pump.
4.Extend the life span of the wells
Comparatively,groundwater entering into screen with higher open area is much easier than the entering into lower open area screen.the slow water flow shall extend the life span of the wells .




End connection: Plain beveled ends for welding or threaded male &female coupling(spiral).




Application : this Rod base wire wrap screen used for water wel ,oil well , underground well , geothermal well , and so on .
