Stainless Steel Johnson Screen /water well screen used for well drilling


Slot opening for stainless steel water well screens are manufactured by spacing successive turns of the outer wire to produce the desired slot size. All slots should be cleaned 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 non clogging, are narrowest at the outer face and widen inwardly. Johnson screens 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 .

5. Long life: 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 non clogging, are narrowest at the outer face and widen inwardly.

Johnson thread stainless steel water well screens provide more intake area per unit area of screen surface than any other type. For any given slot size, this kind of water well screen has maximum open area.
