Product Overview
Description
Johnson screen profile
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 Screens Vee-Wire Profiles
Johnson Screens Vee-Wire Profile wires range in widths from 0.020in.(0.508mm)to 0.195in.(4.953)and heights ranging from 0.040 in. (1.016 mm) to 0.363 in. (9.220 mm). Other wire shapes (Tri-Wire, Iso-Wire, Iso-Grizzly Wire, Grizzly-Wire, and more) also available.
Common Johnson Screens Shaped Support Rods
Johnson Screens shaped support rods range in widths from 0.029 in. (0.737 mm) to 0.151 in. (3.835 mm) and heights ranging from 0.102 in. (2.591 mm) to 0.120 in. (3.048 mm).
Open area calculations
To calculate the open area of a certain screen, use the simple formula provided
Open Area (%) = Slot Size * 100
Slot size + Wire width

Perfect testing equipment to make sure the quality of our products.
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.
