V-Shape wire wedge Johnson screens
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 johnson screens have a strong structure and high open area, as well as accurate slot dimension.
5.Ladder-like wire welded johnson screens have the features of easy backwashing, last long, safety and reliability as well as low comprehensive cost.
Construction:
Each slot opening between adjacent wires is V-shaped, from the special shape of wire used to form the Johnson screens surface. The V-shaped openings designed to be nonclogging, are narrowest at the outer face and widen inwardly:
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 johnson 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.
