Water well 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.

Wedge wire specification and Supports rods specification:
Johnson Screen V-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:

The open area calculation:
To calculate the open area of a certain screen, use the simple formula provided:
Open Area (%)= Slot Size *100/(Slot Size +Wire Width)
Advantages:
1.A continuous slot opening which significantly increases the available open area, thus providing greater access to the water bearing zone
2.A V-shaped profile wire which avoids clogging and ensures an uninterrupted flow.
3.A uniform and efficient well development due to the continuous slot opening.
4.Ladder-like wire welded screens have a strong structure and high open area, as well as accurate slot dimension.
