Water Well Screens Introduction
water well screens are manufactured by a v or wedge shaped wire around an internal
array of longitudinal support rods. Each intersecting point of these wire is fusion welded.
The v or wedge shaped profile wire wraps around the support rods over the full length of the screen creating
a continuous slot opening, hence the screen allows water (oil) to enter your well freely in ample quantities,
while at the same time keeps the majority of sand and gravel out of the well.
Specifications of Water Well Screens
1. Slot size(mm): 0.1~3mm
2. Open area: up to 60%
3. Material: low carbon, low carbon galvanized steel (LCG) steel treated with anticorrosion coating, stainless steel (304, 316L etc)
4. Unit Length up to 6 meters
5. Diameter: ranging from 25 to 800mm
6. End connection: plain beveled ends for butt welding or threaded coupling or flange
Advantage of Water Well Screens
1. Non-clogging construction: The V-shape section plane of wedge wire screens (Johnson type screens) creates the continuous slot, which can avoid blockage and make sure of the unimpeded water.
2. Large Filtering Area: The consecutive slot of wedge wire screens (Johnson type screens) have wider open area,
and it can reduce the speed of the water entering to avoid the sand entering the screen under the great pressure, so it can control sand better,
which can increase the water yield and prolong service time of the well.
3.Long service life Wire and support rods are all-welded, which makes wedge wire screens (Johnson types screens) more robust and longer life.
4.Excellent construction strength: The longitudinal support rods and the continuous slot make the wedge wire screens(Johnson type screens) have more excellent pressure-resistant performance.
5.Specifications and end connections of wedge wire screens(Johnson screens) can me fabricated according to customers’ requirements.
