water well screen pipe, approved by API certificates, high quality and low price, enjoying good reputations.

glavanized water well screen in the all welded continues slot wedge wire to support rod. The dimension of the screen 8 5/8 O.D, 6m length for each pipe, slotted opening 0.75 mm, and the rod. Base screen is medium strength construction, A screen of the all welded wedge wire construction will not plug due to screen is v. shape pattern and will only have two point 

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
