Johnson screens consist of V-shape profile wire and the longitudinal support rods. each intersecting point of these wires is fusion welded. So it has sturdy constriction and good mechanical property. The V-shape section plane can avoid blockage, and make sure of the unimpeded water. Theconsecutive slot have more 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 filter sand better. Meanwhile ,the slot can change according to the real condition of the earth.

Advantage

1.A continuous slot opening which significantly increases the available open area, thus providing greater access to the water bearing zone.

2.A V-shaped profile wire which avoids clogging and ensures an uninterrupted flow.

3.A uniform and efficient well development due to the continuous slot opening. 4.Ladder-like wire welded screens have a strong structure and high open area, as well as accurate slot dimension.

5.Ladder-like wire welded screens have the features of easy backwashing, last long, safety and reliability as well as low comprehensive cost.

Slot opening for continuous-slot screens are manufactured by spacing successive turns of the outer wire to produce the desired slot size. All slots should be clean and free of burrs and cuttings.

Each slot opening between adjacent wires is V-shaped, from the special shape of wire used to form the screen surface. The V-shaped openings designed to be nonclogging, are narrowest at the outer face and widen inwardly; they allow

1. Production process continuity: V-shaped profile wires creating slots which enlarge inwardly and therefore avoid clogging and minimize downtime.

2. Low maintenance costs: Separation at the screen surface which can easily cleaned by scraping or back washing.

3. Maximum process output: Precise and continuous slot openings resulting in accurate separation without loss off media.

4. Low operational costs: Large open area with an effective flow, high yield and a low pressure drop (dP)

5. Long live: Welded at each intersection creating a strong and durable screen.

6. Reduced installation costs: supporting constructions eliminating costly support media and enabling a maximum flexibility in the design of components.

7. Chemical and thermal resistant: A variety of corrosion resistant stainless steel materials and many exotic alloys suitable for high temperatures and pressures.

Each slot opening between adjacent wires is V-shaped, resulting from the special shape of the wire used to form the screen surface. The V-shaped opening, designed to be nonclogging, are narrowest at the outer face and widen inwardly.

Continuous-slot screens provide more intake area per unit area of screen surface than any other type. For any given slot size, this type of screen has maximum open area.
