Johnson wire screens(Johnson Type Water Well Screens) are manufactured by VEE or the wedge shaped wire around an internal array of longitudinal support rods. The word advanced all-weld technology is used with the each intersecting point of these wire fusion welded, which creates robust construction and excellent mechanical performance. The VEE or wedge shaped profile wire wraps around support rods over 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. The slots can be changed according to different strata.
Diameters:10-3/4", Also can make 4-1/2", 6-5/8", 8-5/8", 12-3/4", 14", 16" etc.
Slot size (mm):0.25mm 0.5mm 0.63mm, 0.75mm, 1.0mm, 1.5mm,also achieved upon customer request.
Open area up to 60%.
Material : Low Carbon ,Low Carbon Galvanized steel (LCG),Stainless Steel( 304,etc.)
Length: up to 6 meters. We suggest 2.9m and 5.8m to fit 20GP, and 3m/ 6m to fit 40HC container.
End Connection:Plain beveled ends for butt welding, male/female threaded,Flange etc.

1. Non-clogging construction: The Hot-selling and high-quality water well screens made in China creates the continuous slot, which can avoid blockage and make sure of the unimpeded water
2.Large filtering area: The Hot-selling and high-quality water well screens made in China 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: The Hot-selling and high-quality water well screens made in China have longer and more robust service time
4.Excellent construction strength: The Hot-selling and high-quality water well screens made in China have more excellent pressure-resistant performance
5.Note: Specifications and end connections of wedge wire screens (Johnson type screens) can be fabricated according to customers’ requirements.
