ASTM 159*3mm SS profile wire warpped screen/Johnson strainer/water fliter pipe(ISO certification):
Water Well Screens consist of V-shape profile wire and the longitudinal support rods. Each intersecting point of these wires is fusion welded, so Water Well Screens has sturdy 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 Water Well Screens under the great pressure, so it can filter sand better. Meanwhile, the slot of Water Well Screens can change according to the real condition of the earth.

Advantage of Johnson strainer/water fliter pipe :
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.
5. Ladder-like wire welded screens have the features of easy backwashing, last long, safety and reliability as well as low comprehensive cost.
