Johnson type water well screen pipe consists of V-wire and the longitudinal support rods.
Each intersecting point of these wires is fusion welded, so it has study constriction and good mechanical property.
The V-shape section plane can avoid blockage, and make sure of the unimpeded water.
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 Johnson type well screen can filter sand better.
The continuous-slot well screen is widely used throughout the world for water, oil, and gas wells, and is the dominant screen type used in the water well industry.
