production (water well screen /water well sand filter)

v-wire wrapped screen is  a revolution in technology for the water well industry. The continuous slot screen provided more open area per square foot of screen, allowing more water into the well. the all welded continuous slot wire wrapped well screen was the innovator in screening TECHNOLOGY. Today, Johnson Screens has expanded into many diversified industries such as: - Water Well - Surface Water - Water Treatment - Mineral Processing - Refining and Petrochemical - Food and Beverage - Pulp and Paper - Architecture and Construction - Polyurethane Casting In addition, each of our screening products is backed by our expert field service and technical expertise.

The continuous-slot well screen is widely used throughout the world for water, oil, and gas wells, and is the dominant screen type used in the water well industry  

 advantages(  water well screen/water well sand filter )

1)MAXIMIZING FLOW RATES       water well screen with high open area.(water well sand filter)

2)NON-CLOGGING SLOT      water well screen have V-shaped openings that narrowest at the outer face and widen inwardly. thus, oversized particles are retained outside the screen and particles passing through the narrow outside opening can enter the screen. (water well sand filter)

3)REDUCTIONS IN OPERATING COSTS  

Lower through-slot velocities mean that pressure drops are minimized, therefore;Drawdowns are reduced.Less energy is needed for pumping.Flow rates are increased.

Less sand in the water reduces wear on the pumps(water well screen/water well sand filter)

Features:

1) Vee wedge wire well screens are considered the standard of the industry, combining proven performance with durability
2) Low-carbon, galvanized or stainless steel construction
3) Provide optimum well development and access to the aquifer
4) Large open area This allows more water/ oil to enter at much lesser frictional head loss and the efficiency of well is improoved appreciably.
5) Wate/ oilr enters at lower velocity, reducing screen surface erosion and encrustation
6) Designed and constructed to operate under different depth conditions, with the optimum strength / open area ratio
7) Other installation depth designs available upon requests
8) Non clogging: “ V” shaped profile wire, avoids clogging, is self-cleaning and ensures an uninterrupted flow. Sand grains make only two point contact and don’ t wedge in the screen’ s inwardly enlarging slot.
