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 profiles:

Johnson Screens consist of V-shape profile wire and the longitudinal support rods.The wire is welded to the rods and produces a rigid unit that has high strength and minimum weight.

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:

3. The stainless steel products through galvanized form processing protective cover. Appearance clean.

4. May be based on customer needs to prepare packing.

 

Application :

The continuous-slot well screen is widely used for the construction of the building of the hydrologic geology, Coal Geology, chemical, geological, geothermal air conditioning, foundation precipitation, water source development, urban water supply and other walks of life.

 

 

Features of Johnson well Screen :

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 groundwater's entering into the screen much slower than any other filtration apparatus, which will avoid sand's entering into screen because of high pressure, thus reduce the abrasion of the pump.
4. Extend the life span of wells
Comparatively, groundwater's 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 wells.
