Johnson Type screens

Product description

Johnson Type Screen mostly refers to V - Wire Water Well Screen.

Johnson Type screen is manufactured with V-shaped profile wire which is spirally wound 

around a cage of longitudinal support rods. 

Each intersecting point of these wires is fusion welded. The pitch of winding gives different spacing between two adjacent turns of wire. 

This spacing gives passage for water to enter. 

The entire process is completed on fully computerized machines.

Material 

Low Carbon Galvanized Steel ( LCG ) and Stainless Steel ( SS-304 )

Advantages

 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.
