water well screen are very effective in wells of this type since they can be manufactured with very small slot size and yet still maintain the necessary open area to minimize friction head loss. Most continuous wire wrap screen is manufactured from stainless steel rather than carbon steel in order to avoid problems which often leads to accelerated corrosion. 

Application of water well screen 

Used for Johnson pipe V wire wrap screen tube wedge wire screen:
The stainless steel johnson water well screen pipe is used throughout the world for water, oil, and gas wells, and for environmental well completions. It is the dominant screen type used in the water well industry.

Characteristics of water well screen 

1.They consist of V-shape or wedge shape profile wire and the longitudinal support rods.
2.The consecutive 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 it can filter sand better.
3.Each intersecting point of these wires is fusion welded, so it has sturdy construction and good mechanical property.

Feature of water well screen 

High corrosion resistance
Very accurate slot opening
Minimum risk cementing up
Uncomplicated installation
