Stainless Steel Johnson Water Well Screens

Product intro

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

Advantages

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.

Technical patameter

The V-shaped wire can be made in different height and width to address various strength application, meanwhile, the spacing of individual slots can be varied during fabrication if geologic conditions require these variations in a screen's construction.
