water well screen,well screen

Johnson screens are manufactured with V-shaped profile wire which is spirally wound around a cage of longitudinal support rods. Each intersecting point of these wire 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.

 

Johnson Screens continuous-slot, Vee-Wire construction of rod based screens is known around the world as the industry`s best well screen. Providing more open area, these non-plugging well screens have a tight slot tolerance, effective sand control and a lower entrance velocity.

 

Our manufacturing capabilities cover the full range from shallow wells to deep wells, where the collapse resistance may be achieved with the use of heavy-duty Vee-Wire.

 

Johnson Screens` specific continuous-slot construction aims to optimize flow rates, minimize clogging and help develop the water-bearing geological formations faster. It is best applied in the following situations:

 

Geological formations comprised of small, fine particles

 

Water wells where gravel packs will be installed

 

Thin aquifers, where maximum open area is required

 

Large- and small-diameter deep wells

 

Available for both small- and large-diameter applications, rod based screens are available in stainless steel, low carbon steel and PVC with slot sizes as small as 0.004 in. / 0.1 mm and lengths up to 40 ft. / 12 m.
