Product Description

                                     Johnson Water Well Filter Screen

Definition and Structure
 
- Definition:Also known as wedge wire screen or continuous slot screen, Johnson screen is divided into screen tube and screen plate .
- Structure:It consists of wedge-shape profile wire and the longitudinal support rods. The wedge wire has a triangular cross-section, and is welded to the support rods with a "V"-shaped surface and a "groove"-shaped interior .
 
Characteristics

 - High Strength:The V-shaped wire and support rods are welded together, forming a solid structure that can withstand high pressure and impact.
- High Open Area:The narrow width of the wedge wire and the precise control of the slot size allow for a high open area, increasing filtration efficiency.
- Anti-Clogging:The unique V-shaped design and continuous slot ensure that solids are less likely to get stuck, reducing the risk of clogging.
- Precise Filtration:The slot size can be accurately controlled, enabling the filtration of fine particles with high precision.
 
Materials and Manufacturing
 
- Materials:Common materials include stainless steel, carbon steel, copper, nickel, aluminum, and resin. Stainless steel 304, 316, and 316L are often used for their excellent corrosion resistance.
- Manufacturing:It is usually made by welding the wedge wire to the support rods using specialized resistance welding machines. The outer protective sleeve can be spiral welded.
 
Applications
 
- Water Treatment:Used in groundwater filtration, seawater desalination, sewage treatment plants, and water intake screens to remove impurities and suspended solids.
- Oil and Gas Industry:Screen tubes are applied for sand control and as linings in oil wells to prevent sand from entering the wellbore and damaging the equipment.
- Mining Industry:Employed in grading screening and dewatering operations to separate minerals from the ore and remove excess water.
- Food and Beverage Industry:Utilized for filtering syrups, liquid medicines, and other fluids with high sanitation requirements, ensuring product quality and safety.
- Chemical Industry:Used for filtering and separating corrosive media, providing reliable filtration solutions in harsh chemical environments.

Product Advantage:

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
Product Application:
Johnson screens are widely used in water treatment, environmental protection, seawater conversion,the petroleum industry, and other scenarios
